Product Description:

The 080G0042 is a programmable controller module produced by Danfoss for the MCX Programmable Controllers series. It forms the logic core of HVAC and refrigeration assemblies by executing control algorithms and sampling field signals. The controller energizes outputs so compressors, evaporator fans, pumps, and valves operate in coordinated sequences that maintain the required process temperature and pressure. This centralized control arrangement allows connected equipment to respond consistently to sensor measurements and operating commands.

Field connectivity includes one RS485 port for networked supervision. The board accepts 10 analog inputs for temperature or pressure transducers and provides 15 digital outputs that switch solenoids, contactors, and indicators. Eighteen 24 V digital inputs capture dry-contact status, while six analog outputs handle proportional valve positioning. Internal power usage remains within 12 W, and the integrated supply provides external devices with 200 mA at 12 V. Apparent power drawn from the AC supply does not exceed 20 VA. This capacity supports the processing core, LED indicators, and input and output conditioning circuits without overloading the control transformer.

Four 230 V AC inputs monitor line-voltage feedback points. Actuation capability includes a 16 A high-inrush relay for motor starting and additional contacts rated at 8 A for fans or heaters. The cumulative switched current must remain below 92 A to protect the output bus. PWM and PPM channels activate at 6.8 V and require a minimum load of 1 kΩ to maintain stable duty cycles. Each analog output can source up to 10 mA, supporting compatible proportional control devices. A 5 V auxiliary rail delivers 210 mA for potentiometers or low-power sensors. The available relay, analog, and pulse outputs allow the module to operate mixed-voltage field hardware while keeping individual loads within their applicable electrical limits.
