2.11 Daughter Board

The OME-A-8111 can be connected with many different daughter boards. The function of these daughter boards is described as follows.

2.11.1OME-CA-4002

The OME-CA-4002 is a 37-pin D-Sub male connector. It can directly connect to a 37-pin D-sub connector.

2.11.2OME-DB-16P

The OME-DB-16P is a 16-channel isolated digital input board. The OME-A-8111 provides a 16 channel, non-isolated, TTL-compatible digital inputs from CN2. If connecting to the OME-DB-16P, the OME-A-8111 can provide 16 channels of isolated digital input signals. Isolation can protect the PC if an abnormal input signal is occurs.

2.11.3OME-DB-16R

The OME-DB-16R provides a 16-channel SPDT relay output. The OME-A-8111 provides a 16 channel, TTL-compatible digital output from CN3. If connecting to the OME-DB-16R, the OME-A-8111 can provide a 16-channel relay output to control power devices.

2.11.4OME-DB-37

The OME-DB-37 is a general-purpose screw terminal board. It provides a 37-pin connector. This board directly connects to a 37-pin D-sub connector. It is suitable for easy signal connection and measurement.
