The Mercury & Intuitive Range
From Resource Data Management
For Version Mob 1.0
The Mercury Mk2 Mobile controller is intended for use in refrigeration display cabinets with one or two integral compressors with each
compressor having a temperature probe fitted to enable the compressor to be stopped if a set (discharge) temperature is exceeded. The
controller will switch on one or two compressors based on the average of an air on and air off temperature probes and has outputs to
control lights, fans and defrost control. The lighting relay can be set to operate as an alarm relay if required. The controller also has an
inbuilt defrost timer and 7 day lighting control timer which can also be used to switch the cabinet off and on at specific times, this can be a
useful energy saving feature if the cabinet contains non perishable goods (such as drinks) and can be automatically switched off at night.
There is also a DIN rail mounted version, known as the Intuitive Mercury, which is designed to be used in a control panel or electrical
tray. This range has the same features as the Mercury Mk2 controller with additional benefits such as higher rated relays, each protected
by an integral fuse and fuse protection for the incoming power supply. All connections are plug in socket and there are multiple network
interfaces to choose from including Ethernet.
The controller supports PT1000, NTC2K, 470R, 700R, 3K, 5K, 6K, NTC2K25, NTC10K or NTC10K(2) temperature probes (note: probe
types cannot be mixed)
