OP4512 Standard Configuration


A. DB37 connectors for digital or analog inputs and outputs.

B. In the standard OP4512 configuration, this section contains a DB9 connector module for RS422 signals typically used to transmit differential encoder inputs and outputs, however, other options are available.

C. Standard computer connectors (from left to right):

D. 1 PCIe free slots are available for optional I/O card. See OP4512 PCIe optional I/O cards below.

OP4512 I/O Expansion Options 

The OP4512 comes with an RS-422 Connector Kit (OP5969-1) factory installed by default.

The optional Fiber-Optic Connector Kit (OP5969-2) can also be installed. It will replace the default connector kit, since only ONE of these connector kits can be installed in an OP4512 at a time.

The optional connector kit must be selected at the time of purchase and factory-installed.

If the OP3811 or the OP3812 GPS Synchronization Connectors PCIe I/O cards are ordered, none of the following expansion options can be installed because the I/O cards also require a connector plate to be installed in the same location.

(OP5969-1)

OP4510 V2-1 RS422 Connectors

DEFAULT connector kit installed
The DB9 connectors for RS422 signals are typically used to transmit differential encoder inputs and outputs. Refer to the OP5969-1 User Manual for specifications and pin assignment.

Fiber-Optic Connector kit
(OP5969-2)

OP4510 V2-2 Fiber Optic Connectors

Optional connector kit
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 the OP5969-2 User Manual for specifications and pin assignment.

OP4512 PCIe Optional I/O cards

There are several PCIe options available for the OP4512.


Only ONE of the I/O cards may be installed in an OP4512 at a time.

The PCIe optional I/O card must be selected at the time of purchase and factory-installed.


OP5451
Copper cable

Passive/active PCIe expansion with standard PCIe iPass x4 connector interface. This option is used to connect the OP4512 to an OPAL-RT expansion I/O chassis. The option comes as a kit, including a copper cable.

OP3411

OP3411

CANbus protocol expansion board with a CANbus standard 25-pin connector interface.

OP3811

PCIe I/O Card

OP3811

Connector plate

OP4510 V2-T GPS Synchronization Connectors

The GPS time synchronization (IEEE 1588) with RJ45 connector interface comes in 2 parts: the PCIe card and the connector plate with an external synchronization input connector and fiber-optic synchronization output.

If this option is selected, none of the I/O Expansion Options (OP5969-1, OP5969-2) could be installed because the connector plate needs to be installed at the same place.



OP3812

PCIe I/O Card

OP3812

Connector plate

OP4510 V2-T GPS Synchronization Connectors

GPS time synchronization (IEEE 1588) with SFP connector interface comes in 2 parts: the PCIe card and the connector plate with an external synchronization input connector and fiber-optic synchronization output.

If this option is purchased, none of the I/O Expansion Options (OP5969-1, OP5969-2) could be installed because the connector plate needs to be installed at the same place.

OP3821

OP3821_Ethernet_Backplate

Dual-port PCIe x1 Gigabit Ethernet interface.
