I/O Module Slots

...

Image Added

Up to 2 I/O modules (or IO boards) can be installed in one of the two slot locations of an OP4810-IO or OP4815-IO FPGA Processor and I/O Expansion unit.

...

• Module models are identified OP48Hxx, where “xx” is a number.

  • See available I/O modules here: OP48H00 I/O Modules Series for OP4800 Line of Devices

• SLOT x can be SLOT 1 or SLOT 2

• Each I/O modules provides four (4) DB37 connectors numbered P1 to P4. Each port is labeled with the type of IO:

  • Digital input (Din)

  • Digital output (Dout)

  • Analog input (Ain)

  • Analog output (Aout)

• The pin assignments for each channel depend on the type of module. They are described in the System Description Document delivered with the unit.

  • See also pin assignments here: OP48H00 I/O Modules Series for OP4800 Line of Devices.

RS422 connector kit (OP5969-1)		It is the default I/O module provided with the OP4810-IO/OP4815-IO. The DB9 connectors for RS422 signals are typically used to transmit differential encoder inputs and outputs. Refer to this page for specifications and pin assignments: OP5969-1 RS422 Digital Inputs and Outputs (DIO).
Fiber-Optic connector kit (OP5969-2)		The default RS422 I/O module above provided with the OP4810-IO/OP4815-IO can be replaced by this fiber-optic module. Fiber-optic connector kit provides 6 RX and 6 TX channels. These channels can be used as 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. Refer to this page for specifications: OP5969-2 Fiber Optic Connector.
