Keysight / Agilent 34921A 40-Channel Armature MultiplexerRefurbished
The Agilent 34921A module for the 34980A Multifunction Switch/Measure Unit is the most versatile multiplexer for general purpose scanning. It has low thermal offset characteristics and a built-in thermocouple reference on the terminal block, making it ideal for temperature measurements directly to the internal DMM. The dense, multi-function switching with 100 channel/second scan rates addresses a broad spectrum of data acquisition applications.
Four additional fused inputs (44 channels total) route up to 1A of current to the internal DMM, allowing AC and DC current measurements without the need for external shunt resistors. Standard 50-pin Dsub connectors allow for use with standard cables, terminal blocks, or mass interconnect solutions.
The 34921T is a terminal block for the 34921A 40-channel multiplexer and the L4421A 40-Channel LXI armature multiplexer. It offers a built-in thermocouple reference junction that helps minimize errors due to thermal offset when you measure thermocouples. This terminal block is used for discrete wiring. It supports up to 20 AWG wire size typical for <100 connections or 24 AWG for >100 connections. The 34921T is a detachable terminal block with screw-type connections that provides a flexible method for connecting external wiring.
