OP8710 System Description
Page Contents
Description
The OP8710 High Voltage Interface Panel (HVIP) can provide digital signals of up to 250 VDC to external equipment and provides up to 16 such signals.
OPAL-RT's digital outputs control the relay switch located between the +VDC and +LOAD connections.
The HVIP uses 8 Brentek International dual channel solid-state output modules for the 16 output channels.
Each output module can switch up to 250 mA at 250 VAC/VDC.
The module is operated using an active-low signal provided by the OPAL-RT simulator.
The module output contact is closed when 0 volts are applied to the control input.
When the module contact is closed, the relay status LED is ON.
If no connection is made to the control input, then the module contact is open.
The DB37 connector uses the same pinout as the OP5600 and OP5700 families of chassis.
CAUTION: When making connections between the HVIP and the external equipment, ensure that the +VDC voltage supply is turned OFF.
Typical Application Diagram
NOTE that the OP8710 is equipped with a watchdog.
The watchdog receives synchro pulses from the target’s FPGA, which is in turn what drives the relays (with the 24 V power received through the watchdog).
If the watchdog stops receiving the synchro signal for any reason (this indicates that the model has reset, crashed, etc.), it cuts the 24 V at source, and this in turn opens all the relays.
Watch Dog Signal Conversion
The OP8710 watch dog uses an electrical signal from a copper wire. If your target is recent, it may only have fiber-optic synchronization.
In this case, you may use the OP5966 RTSI Signal Converter module between the target and the OP8710 High Voltage Solid State Relay Box to convert the synchro signal from copper to fiber-optic
