3.2 Daughter Board
The OME-A-822PGL/PGH can be connected with many different daughter boards. The daughter boards are described below:
3.2.1OME-DB-8225
The OME-DB-8225 provides an on-board CJC(Cold Junction Compensation) circuit for thermocouple measurement and a terminal block for easy signal connection. The CJC is connected to A/D channel_0. The OME-A-822PGL/PGH can connect to an OME-DB-8225 through a 37-pin D-sub connector on CN3.
3.2.2OME-DB-37
The OME-DB-37 is a general purpose 37-pin screw terminal board. It connects to a 37-pin D-sub connector.
3.2.3OME-DB-16P
The OME-DB-16P is a 16 channel isolated digital input board. The OME-A-822PGL/PGH provides 16 channels of non-isolatedTTL-compatible digital inputs via the CN1 connector. If used with the OME-DB-16P, the OME-A-822PGL/PGH can provide 16 channels of isolated digital input. Isolation can protect the computer if abnormal or excessive input signals are received.
3.2.4OME-DB-16R
The OME-DB-16R provides 16 SPDT relay outputs. The OME-A-822PGL/PGH provides 16 TTL-compatible digital outputs via CN2. If connecting to the OME-DB-16R, the OME-A-822PGL/PGH can provide 16 relay outputs to control external devices.
