3 878 Distributed Input/Output Device The Bitronics 878 DIOD is a self-powered, distributed I/O device that provides combinations of digital inputs, digital outputs, and transducer inputs. All I/O is accessible via IEC or DNP3 protocols for substation equipment monitoring. The 878 DIOD with its substation hardened design and flexible distributed communications capability allows it to be installed virtually anywhere in the substation. Features of the 878 DIOD include: Three chassis sizes A host processor with four serial ports A wide-range universal power supply Accommodates an optional Ethernet module (standard for IEC 61850) as well as three to six I/O modules depending upon the chassis Built from the M871 platform, with over ten years field experience, the 878 DIOD carries the Bitronics tradition of offering unmatched quality and reliability. Key Features Flexibility: Back of panel mounting, three chassis sizes, digital inputs/outputs and transducer inputs, and multiple protocol support. International Appeal: CE marked and supporting IEC with GOOSE messaging. Simplicity: Easy setup of DNP3 via the 70 Series Configurator, (coming in 2013) via the NovaTech Communications Director (NCD). Fast Control: Interfacing with the NovaTech OrionLX enables fast control. Rugged Design: Substation hardened design with proven Bitronics quality and dependability.

5 Application Examples Orion High Speed Control Application Bitronics 878 #1 and #2 send Orion GOOSE messages containing realtime input conditions. Orion performs math and logic on these and sends output to GOOSE message to 878 #3. Total cycle time can be less than one cycle (16ms) IEC GOOSE Messaging 878 #1 878 #2 878 #3 Inputs Inputs Outputs High Speed Logic on 878 DIOD Boolean logic can be set up on the Bitronics 878 DIOD. In this example, if both Inputs #1 and #2 are ON, and analog input #1 is greater than 200, then virtual output #7 turns ON BITRONICS 878 DIOD APPLICATION NOTE l 5

6 Details The Bitronics 878 DIOD provides digital I/O and transducer input points accessible via IEC and DNP3 protocol. Both serial and DNP3 over Ethernet are supported, and IEC GOOSE communication is also supported. The 878 DIOD is built from the M871 Monitoring and Recording IED platform and utilizes the same H12 host, E1 and E3 Ethernet options, V10 Power Supply, P31/P30A Digital I/O, and P40 transducer input modules. The 878 DIOD is available in three rugged aluminum chassis sizes supporting up to six (6) optional I/O modules. A maximum of 56 binary inputs, 24 binary outputs, or 48 transducer inputs are supported (with no Ethernet). The 878 DIOD can accept an IRIG-B time synchronization signal via one of its three configurable serial ports, permitting time stamping of events accurate to one millisecond or better. Configuration is via the 70 Series Configurator as well as the IEC Configurator. The digital outputs are controlled via CONTROL RELAY OUTPUT BLOCK objects and support LATCH-ON, LATCH-OFF, PULSE-ON, and PULSE- OFF commands. The 878 DIOD can report all input changes as DNP3 events. The digital inputs can be assigned to any of the DNP3 classes via the ASSIGN-CLASS function or via the 70 Series Configurator. IEC GOOSE can generally be envisioned as a way to communicate a binary status over an Ethernet medium, exactly analogous to status and control performed by discrete I/O points. GOOSE messages are reliable enough to be used for controlling interlocks and protective relay blocking schemes, and can be propagated even faster than discrete digital contacts because of the time that it takes for moving mechanical parts to operate. Individual SOE reports can be generated within each 878 DIOD. An OrionLX can generate SOE reports by monitoring events from multiple 878 units. The Bitronics 878 DIOD is shown in the wide chassis with standard V10 power supply and H12 host processor with E3 RJ45 plus 100FX Fiber Ethernet port, plus six optional P30A digital I/O modules. The E1 Ethernet option with 10/100 Mbps RJ45 only is also available. 6 l BITRONICS 878 DIOD APPLICATION NOTE

The load might be the trip or close coil of a breaker, a discrete input on a RTU or an annunciator, or just an indicator lamp on a panel. It could be a permissive or blocking contact in a trip circuit. BITRONICS 878 DIOD APPLICATION NOTE l 9

12 Combined Input & Output (Points 1-4 on P30A and P31 DIO Cards) LOAD ~2.5Vdc 125Vdc + 125V 15 = 816μA NO NC Digital Output DO=0 DI=1 Output Note that when the digital output is open, a trickle of current continues to flow through the load because of the parallel digital input circuit. Due to loop-resistance, this trickle is typically less than 1mA, so is insufficient to operate trip/close coils on breakers, but could certainly be enough to energize a solid-state load like an LED indicator lamp. If the trickle current is undesirable, the resistor (circled in red) may be removed either in the field with a pair of cutters, or from the factory by special order and then the DI=0. LOAD 125Vdc + NO NC Digital Output DO=0 DI=0 Output Output jumper configured in NC position. Output functions as normally closed. If external wetting voltage is applied, the input senses logical 0 when output is closed, logical 1 when output operates. In other words, the input reflects the position of the output rather than its inverse. NOTE: Digital outputs may be configured with logic via software settings to operate either when a condition exists or when it does not exist. But only the hardware jumper (circled in red) can control what condition the digital output returns to if power is interrupted or the device resets. This is an important consideration to avoid nuisance tripping. 12 l BITRONICS 878 DIOD APPLICATION NOTE
