1 LOGIC Component Technology LOGIC & INTERFCE The Defined Logic component is an 8-pin logic and interface device developed as a part of the LOGIC Series by NEXSYS. The Defined Logic component replaces traditional relays and diode (oolean) logic currently used to generate conditional logic applications. Defined Logic can be integrated into a traditional 4-pole switch housing, creating a LOGIC ody (L), or can be inserted into a stand-alone LOGIC Module (LM) for use behind the panel. Defined Logic can also be combined with electromechanical switches and other LOGIC Series components to create a custom configuration that uniquely addresses the designer s specific functional requirements. Defined Logic is designed and tested in accordance with MIL-PRF and DO-160. Defined Logic Replaces power or ground drop out relays oolean ND, OR, NOT (), and Exclusive OR capability 2 and 4 input versions available ble to detect changes from either power or ground Low power Decode up to 4 separate binary or CD inputs High Capacity LOGIC ody as shown contains Defined Logic, single switch pole and 4-pin LOGIC component LOGIC Module as shown contains Defined Logic and 4-pin LOGIC components Overview The LOGIC Series Defined Logic (DL) component provides the ability to generate decision (oolean) logic and provide interface drive capability. This enhanced functionality provides the ability to replace relay and diode logic. How it works: The Defined Logic contains an integrated electrical circuit that is configured to a defined (oolean) logical function. The output will change state to either ground (0) or high impedance (1) when the defined input condition(s) is/are present. See Figures 1.3, 2.3, 3.4 and 4.1 for the available defined conditions. VIVISUN offers 4 distinct variations of the Defined Logic. Each of the variations contains 4 inputs ( D) and 2 outputs (Y and Z). See overview diagram (right). In each of the variations, the designer must also specify the default polarity of inputs and C. The unit is factory configured at time of manufacture to the desired variation and logic level. DL2 (see Figure 1) - Dual (2) independent oolean logic channels, each with 2 inputs and 1 output. This variation has the ability to provide straight oolean logic, an inverter, or a buffer on each independent channel. DL4 (see Figure 2) - 4 discrete inputs and 2 orthogonal outputs DL3 (see Figure 3) - 2 level cascaded logic combining output of 2 logic gates into a third logic gate DL1 (see Figure 4) - oolean Exclusive OR (XOR) logic module, with 2 pairs of tied inputs and 2 orthogonal outputs Data Sheet: DS-DL-13

2 DL2 & DL4 Figure 1: DL2 - Dual (2) Independent Channels, 2 Input and 1 Output Logic The DL2 variant of Defined Logic provides 2 logically independent channels, each of which is capable of delivering one of 10 types of logic functions: ND/OR; outgoing High (1) or Low (0) based on specific conditions existing on the channel inputs (Logic Options 1-8) uffer; output follows one of the input signal s polarity () ; output is the opposite of one of the input signal s polarity (N). uffer () and (N) may be used to replace inverter and buffer relays in the aircraft, including the traditional drop out relay used to activate an indicator upon loss of system power or ground. See pplication Example. Input pins and C must be specified to default as either Pull-up or Pulldown at time of order (See Fig. 1.2), which determines the default input logic level when the pin input signal is Open or floating. Input pins and D are factory configured as Pull-up. See Figure 5 for additional information regarding proper default determination of input pins and C. Figure 1.1 Figure 1.2 Y Output (Channel 1) Logic Options N / / / / + + / / + / + / uffer Y= Y=/ Z Output (Channel 2) Logic Options N C D C D C /D /C D /C /D C + D C + /D /C + D /C + /D uffer Z=C Z=/C Figure 1.3 Figure 2: DL4-4 Discrete Input, 2 Orthagonal Output Logic The DL4 variant of Defined Logic provides the ability to monitor and decode up to 4 discrete inputs and provides 2 orthogonal outputs. Output Y will be normally Ground until a single set of conditions exists on the four ( D) discrete inputs. When the single set of conditions occurs, output Y will go High Impedance. See Fig. 2.3 below. Output Z is the opposite of output Y. Output Z will remain High Impedance until the same set of conditions specified above occurs, at which time it will become Ground. See Fig. 2.3 below. Input pins and C must be specified to default as either Pull-up or Pulldown at time of order (See Fig. 2.2), which determines the default input logic level when the pin input signal is Open or floating. Input pins and D are factory configured as Pull-up. See Figure 5 for additional information regarding proper default determination of input pins and C. DL4 also acts as a 4-bit binary or CD decoder. Examples: DL4/F7/UD would produce a High output on Y and a Ground output on Z when and only when input and D are High simultaneously with inputs and C being Low. In all other cases, output Y will be Ground and output Z will be High Impedance. DL4/G5/DD would produce a High output on Y and a Ground output on Z when and only when input C and D are High simultaneously with inputs and being Low. In all other cases, output Y will be Ground and output Z will be High Impedance.

3 DL3 & DL1 X Figure 3: DL3-2 Level Cascaded Logic The DL3 variant of Defined Logic provides a cascaded result for 2 logically independent channels that are logically combined into a second level 2 input Logic Gate. This reduces the number of Defined Logic units required to implement complex logic functions. Logic Gates 1 and 2 are capable of delivering one of 10 types of logic functions (See Fig. 3.3). uffer () and (N) may be used to replace inverter and buffer relays in the aircraft, including the traditional drop out relay used to activate an indicator upon loss of system power or ground: ND/OR; outgoing High (1) or Low (0) based on specific conditions existing on the channel inputs (Logic Options 1-8) uffer; output follows one of the input signal s polarity () ; output is the opposite of one of the input signal s polarity (N). Output Y (Gate 3) will be normally ground until a single set of conditions exists on the outputs of Gate 1 (T Output) and Gate 2 (S Output), as determined by the selected configuration from Figure 3.4 (N1 N4). Output Z is the opposite of Output Y. Input pins and C must be specified to default as either Pull-up or Pulldown at time of order (See Fig. 3.2), which determines the default input logic level when the pin input signal is Open or floating. Input pins and D are factory configured as Pull-up. See Figure 5 for additional information regarding proper default determination of input pins and C.

DL1 logic will provide a High Impedance signal on output Y when both pairs of input are identical, and will provide a Ground signal when one pair is ground and the other pair is High Impedance. Output Z is the opposite of output Y. See Fig Input pins and C must be externally tied together and must be specified identically to default as either Pull-up or Pull-down at time of order (See Fig. 4.3), which determines the default input logic level when the input signal is Open or floating.

Input pins and C must be specified as either Pull-up or Pull-down at time of order. For the DL1 variant only, input pins and C must be specified identically as either Pull-up or Pull-down since they must be externally tied together. Input pins and D are factory configured as Pull-up. For pins and C: If input signal polarity is normally transitioning between Ground and Open, specify Pull-up (U) such that the input signal will default to High (1) when the input is Open or floating. If input signal polarity is normally transitioning between Open and +28 V, specify Pull-down (D) such that the input signal will default to Low (0) when the input is Open or floating. If input is switching between +28 V and Ground, either Pull-up (U) or Pull-down (D) may be used since no floating condition exists. If an input pin remains unused, its input logic level (0 or 1) is defined by its Pull-up (U) or Pull-down (D) configuration. DL-3

4 PPLICTION EXMPLE pplication Example System Fail Indication performs the function of the traditional drop relay. The unit can turn on the output to drive an indicator or failure signal from either the loss of power or ground. Channel 1 is configured to replace a loss of power (+28 VDC) drop-out relay. When the input to pin transitions from power to high impedance the output Y becomes ground to tum on the indicator. Pin is configured as pull-down so an open (High impedance) on input is recognized as a logic low. Channel 1 logic configuration is a uffer (). Channel 2 is configured to replace a loss of ground drop-out relay. When the input to pin C transitions from ground to high impedance the output Z becomes ground to tum on the indicator. Pin C is configured as pull-up so an open on input C is recognized as a logic high. Channel 2 configuration is (N).
