Highlights

  • 40 2-wire channels
  • 300 V, 1 A switch; 2 A carry current
  • 100 ch/s scanning
  • Mix 2- or 4-wire configurations
  • Built-in thermocouple reference junction
  • 4 current channels
  • Latching armature relays, with relay counter

The Keysight 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 1 A 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.
