AM25T 25-Channel Solid State Multiplexer
The AM25T sequentially connects up to 25 thermocouples or other low-level voltage output sensors to a common differential channel. The output from this channel is wired to a differential input channel on the datalogger. As the AM25T sequentially changes channels, the datalogger measures the output from each thermocouple in sequence. Type T, E, J, and K thermocouple measurements are standard; other thermocouple types are also supported (depends on datalogger model and operating system).
