Test & Measurement Equipment - Sales, Service,Rental and Calibrations

The Agilent L4421A is a high-performance 40-channel armature multiplexer that is LXI Class C compliant. With its small size and Ethernet connectivity, this switch can be placed wherever your application needs it.

The L4421A is a versatile multiplexer for general purpose scanning. The low thermal offset characteristics and built-in thermocouple reference on the terminal block, make it ideal for temperature measurements with an external multimeter. The dense, multi-function switching with 100 channel/second scan rates addresses a broad spectrum of data acquisition design verification, and functional test applications.

Four additional fused inputs (44 channels total) route up to 1A of current to an external multimeter, 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.

Also consider the 34980A 8-slot switch/measure unit that allows you to mix and match different modules into an low-cost, compact solution.
