40-Channel LXI Armature Multiplexer

Manufacturer's part number :

L4421A

Manufacturer Agilent Technologies

Keysight Technologies

Description :

The L4421A is a versatile and high-performance 40-channel armature 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 when used with an external multimeter. 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.
