Product Description:
The Keysight 34921T is a junction box for the 34921A 40-channel multiplexer and the L4421A 40-channel LXI araxial multiplexer. It provides a built-in thermocouple reference node that helps minimize errors due to thermal bias when measuring thermocouples. The junction box is used for separate wiring. At up to 20 AWG line sizes, it can support less than 100 connections; At 24 AWG line size, it can support 100 or more connections. The 34921T is a detachable threaded connection junction box, which provides a flexible connection method for connecting external cables.
Product Features:
Module design: An optional plug-in module that can be used to build compact data loggers, full-function data acquisition systems or low-cost switching units.
Easy connection: The screw connection design on the module makes wiring easier, and this design does not require additional terminal junction boxes.
Simple maintenance: With a unique relay maintenance function, it can record the closing times of each switch, which is convenient for the expected relay maintenance.
