Scanner/ Multiplexer and Annunciator

The Minimux is a microprocessor-based eight channel analog input scanner/multiplexer and annunciator that provides automatic switching for multi-point display and alarm systems. Each unit can automatically switch up to eight inputs to another device such as a digital panel meter, controller or PLC. Multiple units can be connected together to scan an unlimited number of points.

Front panel features push-buttons for programming of independent adjustable dwell times as well as channel skipping. External scanning allows an external device such as a PLC or DCS to direct which channel to scan and for how long. The built-in annunciator logic can detect and indicate which input signals are in alarm condition. The built-in horn, alarm relay, and front panel LEDs are
sure to catch the operators attention. Signal switching is done with reed relays making the Minimux ideal for switching thermocouples, RTDs, control loops, and AC & DC signals.
