3.2 Daughter Board
The OME-A-822PGL/PGH can be connected with many different daughter boards. The
daughter boards are described below:
3.2.1 OME-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.
3.2.2 OME-DB-37
The OME-DB-37 is a general purpose 37-pin screw terminal board. It connects to a
37-pin D-sub connector.
3.2.3
OME-DB-16P
The
OME-DB-16P
OME-A-822PGL/PGH provides 16 channels of non-isolated TTL-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.
3.2.4 OME-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.
