Minimux® Analog Input Scanner/Multiplexer/Annunciator

The Minimux® is a microprocessor-based eight channel Analog Input Scanner/Multiplexer and Annunciator that provides low cost automatic switching for multi-point display and alarm systems. Each Minimux® 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 push-buttons allow for easy programming of independent adjustable dwell times as well as rapid 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 an operator's attention. Signal switching is done with reed relays making the Minimux® ideal for switching thermocouples, RTDs, control loops, and AC & DC signals.
