mV input multiplexer module

The YOKOGAWA AMM22M is an mV input multiplexer module for the CENTUM CS 1000 / CS 3000 distributed control systems. It is designed to receive low-level millivolt signals from field sensors, typically thermocouples or shunt-based measurement circuits.

The YOKOGAWA AMM22TJ is a thermocouple/mV input multiplexer module for the CENTUM CS 1000/CS 3000 distributed control system. It receives up to 16 channels of thermocouple or millivolt signals, with channel 16 used for the RJC (Reference Junction Compensation) port on this variant.

The Yokogawa AMM25C is a 15-channel mV input multiplexer module with a dedicated thermocouple interface and Reference Junction Compensation (RJC) input port for the CENTUM CS, CS 3000, and CENTUM VP distributed control systems (DCS). It is optimized for high-accuracy millivolt measurement and direct thermocouple input, making it a key module for temperature-critical process applications.

The Yokogawa AMM22C is a millivolt (mV) input multiplexer module for the CENTUM CS 3000, CENTUM CS 1000, and CENTUM VP distributed control systems (DCS). It provides 16 isolated analog input channels for low-level signals, multiplexing them through a shared conversion path to reduce hardware complexity. The "-C" suffix denotes a connector-type interface (requiring a mating cable) rather than screw terminals.
