OP5969-1 RS422 Digital Inputs and Outputs (DIO)
The OP5969-1 is an I/O expansion option available for many OPAL-RT’s simulators and FPGA Processor and I/O Expansion Units.
The I/O Expansion connects to the rear interface of the simulator and provides 4x DB9 connectors containing 6 TX and 6 RX for RS422 signals.
These signals are typically used to transmit differential encoder inputs and outputs.
