Agilent, 34903A, 20 Channel Actuator General Purpose Switch Keysight Card Module

Detailed Condtion : in very good condition

The Agilent 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.

Modules specifications
The Agilent 34970A accuracy specifications already include the switching offset and reference junction errors shown in the chart. These errors are listed separately for determining system error with external measurement devices. These errors are listed separately for determining system error with external measurement devices.

Up to three modules, in any combination, can be inserted into a single mainframe. The 34970A’s internal DMM connections are accessible only through the 34901A, 34902A, and 34908A low frequency multiplexers.

On-module screw terminals accept wire sizes from 16 gage to 22 gage. Twenty-gage wire is recommended for high channel count applications. The 34905A and 34906A RF Multiplexers use SMB connectors. A standard set of (10) BNC-to-SMB adapter cables is provided with each RF module for convenient BNC connections.
