• 20 Channel Actuator/GP Switch
• SPDT (Form C) latching relays
• 300 V, 1 A actuation and control

The Keysight 34903A is a general-purpose switch module for the 34970A/34972A Data Acquisition/Switch Unit. 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.

Price and performance beyond compare
Go ahead and compare the Keysight Technologies, Inc. 34970A and 34972A Data Acquisition/Switch Units with other data acquisition systems currently available. You’ll find it hard to come up with a system that offers the powerful measurement performance, flexibility, connectivity
options and ease of use of the 34970A/34972A—even in systems costing three to five times as much. What can you expect from a data
acquisition system that’s this affordable?

Measurements you can trust
We took the measurement engine from our best-selling benchtop DMM and embedded it inside a 3-slot mainframe. You get the benefit of proven Keysight measurement performance, universal inputs with built-in signal conditioning, and modular flexibility, all in a low-cost, compact data
acquisition package. The 34970A/34972A features 6½ digits (22 bits) of resolution, 0.004% basic dcV accuracy, and ultra-low reading noise. Combine that with scan rates of up to 250 channels/sec, and you’ve got the speed and accuracy you need to get the job done right the first time.
