Product Description:
The Keysight 34921A module for the 34980A multifunctional switch/measurement unit is the most versatile multiplexer for general scanning. It has a low thermal bias feature on the end module and a built-in thermocouple reference, which is used in combination with a built-in digital multimeter, making it an ideal temperature measurement tool. This high-density, multifunctional switch offers scan rates of up to 100 channels per second for a wide range of data acquisition applications.
Four additional inputs with fuses (a total of 44 channels) send up to 1A current to the internal digital multimeter, allowing AC and DC current measurements without the use of external shunt resistors. Standard 50-pin Dsub connectors can be used with standard cables, terminal blocks, or high-capacity interconnect solutions.
