HP 34903A 20 Channel Actuator/GP Switch

[ Summary ][ Features ][ Specifications ][ Key Literature ][ Ordering ][ Assistance ][ Related ]
This general-purpose switch module has 20 independent single-pole, double-throw (SPDT) relays. Use it 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 300V, 1A contacts can handle up to 50W, enough for many power line switching applications.

Module Specifications

Up to three modules, in any
combination, can be inserted into a single mainframe. The HP 34970A's
internal DMM connections are accessible only through the HP
34901A, HP 34902A, and HP 34908A low-frequency multiplexers.
On-module screw terminals accept wire sizes from 16 gage to 22 gage.
20 gage wire is recommended for high channel count applications.
