The OP5969-1 is an I/O expansion option available for the OP4510, OP4512, and OP4610XG simulators and also for the OP4520 I/O expansion unit.
The I/O Expansion connects to the rear-interface of the simulator and provides 6x fiber optic connector pairs (input and output).
6 fiber optic inputs and 6 fiber optic outputs can be used for digital I/Os or for low-speed communication protocols.
The ORION protocol, developed by OPAL-RT, is compatible with these channels and available in custom bitstreams.
