11 Trusted High Integrity Power Supply System 1. Description 1. Description The Power Supply Assembly consists of a Power Supply Chassis containing up to six Power Supply Modules. The Chassis may be configured to distribute power in various combinations. For example, a Chassis containing six Power Supply Modules may be set up with three Modules providing triplicated power for Regent+Plus Input/Output (I/O) assemblies and three Modules providing field power in a N+1 configuration. Alternatively, the Chassis may be set up to provide separate dual 24 Vdc supplies for both a Trusted System and associated field devices Power Supply Chassis Figure 1 Power Supply Assembly The Power Supply Chassis houses a maximum of six Power Supply Modules. It may be mounted in a 19-inch rack or flush mounted on a panel. Table 1 identifies the available types of Chassis.

The filters attenuate any high frequency common mode and normal mode noise present in the power distribution system. The MOVs clamp high voltage transients. Filter, rectifier, and power factor correction circuits convert primary ac input power to bulk dc voltage. The switching regulator converts bulk dc power to regulated dc output voltage. Sensing, status, control and timing circuits provide for the following: Input power failure - Active low status output. Indicates when the input voltage is below 85 Vac or 18 Vdc. There is a separate signal for each input. Bulk power failure - Active high status output on ac input modules only. Indicates the dc bulk voltage (power factor correction (PFC output)) is outside the specified range. There is a separate signal for each input. High temperature warning alarm - Both an active high and active low status output are provided. Indicates when the module temperature exceeds 75 C. The temperature is sensed near the air inlet (bottom) of the module. High temperature shutdown - Internal signal that will shut down the switching regulator if module temperature is above 85 C. The temperature is sensed near the air inlet (bottom) of the module. Output over-voltage - Internal signal that will shut down the switching regulator if the output voltage exceeds +18 Vdc for the 15 volt module and +28 Vdc for the 24 volt module. Over-voltage protection circuitry activation is a permanent error condition, requiring manual intervention to return module to normal operation. Rockwell Automation Publication PD_T8200 Issue 11 5

14 1. Description Trusted High Integrity Power Supply System dc output fail - Active high status output indicates the dc output voltage has gone out of regulation. The dc output fail threshold is Vdc (±0.25 Vdc) for the 15 volt module, and Vdc (±0.25 Vdc) for the 24 volt module. Output current limiting - Internal signal limits output current in excessive current demand situations. POWER FAIL - Active high status signal that indicates impending loss of output power due to one of the following: o Both inputs have indicated power failure. o Remote off control signal activated. o Thermal shutdown. o Output over-voltage. RESET - Active high status signal that is generated a minimum of 10 ms (ac input module) or 0.5 ms (dc input module) after a POWER FAIL signal. RESET remains asserted for 200 ms (minimum) after module power-up. PFC off - Active low input that turns off the power factor correction of an individual input. This signal provides the capability to test the input circuitry of a module by turning off each input independently while monitoring the module fail signal. Remote off - Active low input that turns off the output power of a module. Note: Bulk Power Fail, PFC Off and Remote Off are accessed through the Monitor Module Connector on the chassis backplane. The Monitor Module Connector allows for a future development of a monitor card that would provide remote control and enhanced monitoring of the Power Supply Chassis. Active low signals are not maintained while RESET is active. All status signals are open collector and require external pull-up resistors. RESET is used in the Regent I/O Transceivers for power system interlocking within the I/O system. A power failure (either input power or module fault) activates RESET and turns off the dc output Front Panel Indicator. The POWER FAIL and RESET signals are required for proper operation of Regent I/O Transceivers and I/O modules during power-up, power down, and loss of power. Refer to Assembly Installation in the associated Regent Product Description for details of connecting these signals to a Regent I/O Chassis. 6 Issue 11 Rockwell Automation Publication PD_T8200

15 Trusted High Integrity Power Supply System 1. Description 1.4. Front Panel Indicators The Front Panel of each I/O Power Supply Module supports three Light Emitting Diode (LED) indicators detailed in the following sub-paragraphs Input Power Voltage Indicator Each green INPUT POWER indicator is lit when the associated input (Input A, Input B) is above the lower input voltage threshold Output Power Display The 10-segment LED indicator bar displays the approximate output current level percentage (0 % %) Output Power Indicator The DC Output indicator is lit when the I/O Power Supply Module's dc output is within tolerance. Out-of-tolerance conditions, loss of input power or brown-out, and module failures turn off this indicator. Rockwell Automation Publication PD_T8200 Issue 11 7

18 2. Installation Trusted High Integrity Power Supply System Mounting flanges can be attached to either the rear or the front of the Chassis. This allows flush mounting the Chassis to a panel or mounting in a 19-inch rack. The Input Crossover Patch is on the T8200 chassis only. Input Crossover Patch configured for no crossover, source 1 and source 2 are connected to input A and input B respectively for all modules slots. Input Crossover Patch configured to swap source 1 and source 2 for modules slots 4 through 6. Source 1 and source 2 are connected to input A and input B respectively for slots 1-3.

21 Trusted High Integrity Power Supply System 3. Configuration 3. Configuration 3.1. Current Sharing The Modules are capable of current sharing by connecting their outputs together in parallel. This can be done external to the Chassis or by using a shorting bar that mounts directly to the output terminals on the Chassis backplane. This allows separate groups of Modules from within a single Chassis to have their outputs configured as Single, Dual or N+1. The Module uses a passive droop method of current sharing and will share to within 25 % of the rated load REGENT Power Supply Load Units When using the Power Supply System with Regent and Regent+Plus, power supply loading is based on the number of I/O Modules in the I/O Chassis and the load imposed by each I/O Module. Load units for each I/O Module are shown in that Module s product description and specification sheet under the Safetybus Power heading. A set of three Power Supply Modules will provide the following load units: Number of I/O Units (Chassis): Load Unit Capacity: Table 6 Available Load Units (for a set of three power supplies) Calculating the number of load units in the system helps determine the number of I/O Power Supplies required by the system. For economic power distribution, and to avoid overloading individual Power Supply Units, calculate power supply loading when configuring systems Regent I/O Triplicated Power Distribution A Chassis can contain two sets of triple-redundant Power supplies for Regent I/O. Each of the triple-redundant I/O Power Supply Modules within the I/O Power Supply Chassis provides power for one leg of the three redundant legs of the I/O Safetybus Transceivers, and provides power to all the I/O Modules within its associated I/O Chassis. Each I/O Module contains a diode OR power-sharing circuit that receives power from all three I/O Power Supply Modules. Should any I/O Power Supply Module fail, only one leg of the transceiver modules loses power: the two remaining legs maintain proper Regent operation. In addition, all the I/O Modules continue to operate properly by drawing their current from the two remaining Power Supplies within the I/O Power supply assembly.

23 Trusted High Integrity Power Supply System 4. Maintenance 4. Maintenance No periodic maintenance or calibration is required for I/O Power Supply Modules. There are no user-replaceable parts.
