RDM introduces Mk3 Mercury

Mercury-Mk3UK: Resource Data Management has introduced a Mk3 version of its Mercury controller.

The Mercury controller provides users with both internal and remote display options, an increased number of analogue inputs, two new dedicated digital inputs and a built-in IP network interface.

The Mk3 has flexible I/O – 10 inputs and 5 outputs, made up of 6 resistive temperature probe inputs, 2 dedicated digital inputs and 1 x 0-10v or 1 x 4-20ma analogue inputs, and 5 relay outputs, 6A resistive and 2A inductive. All inputs and outputs have a plug-in socket for ease of installation and the latest microcontroller technology for greater processing power and memory capacity.

Widely used in refrigerated display cabinets and coldrooms, the Mercury can control a PMV valve (LLV or EEV) based on the temperature or pressure input value, as well as being able to control lights, fans, suction valve, trim heaters and defrost.

Optional variable inputs allow for reading a pressure transducer, along with two additional digital inputs over and above the existing switched resistor digital inputs.

Energy saving features including pulsed trim heaters or case off with lights parameter
