This module contains 20 independent SPDT (Form C) latching relays. Screw terminals on the module provide access to the Normally-Open, Normally-Closed, and Common contacts for each switch. This module does not connect to the internal DMM.
Note: The DAQ application does not support direct control of channel operations on the non-scanning (switching) modules. You can, however, configure alarm conditions on the scanning modules to control operations, such as closing or opening channels, on the non-scanning modules (see Alarm Limits).
Notes:
You can close multiple channels at the same time on this module.
