Keysight Technologies DAQM903A

The Keysight DAQM903A is a general-purpose switch module Data Acquisition System. It has 20 independent single-pole, double-throw (SPDT) relays and is used to cycle power to products under test, control indicator and status lights, and to actuate external power relays and solenoids. Combine it with matrix and multiplexer modules to build custom switch systems. Its 300 V, 1 A contacts can handle up to 50 W, enough for many power-line switching applications.
