Keysight L4421A 40-Channel Armature Multiplexer

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.

The Keysight L4400 Series LXI instruments are high-performance LXI Class C compliant instruments that encompass all benefits of LXI with an Ethernet connection, instrument Web server, standard software drivers and more. With their small size and Ethernet connectivity, these instruments are easily placed anywhere on the network.
