Data Sheet
Programmable controller, 6 relays
Type MCX061V
Electronic controller suitable for all HVAC/R software application needs.
MCX061V is a standard MCX electronic controller with one integrated electronic expansion valve driver. It is available in the version with graphic LCD display and 110 / 230 V AC or 24 V AC power supply. It holds all the typical functionalities of MCX controllers in the compact size of 8 DIN modules:
• Programmability
• Connection to the CANbus local network
• Modbus RS485 serial communication interface
It is moreover •tted with a slot for memory card SD / MMC and Ethernet connection. The memory card assures SW download and datalogging function; the Ethernet port allows the SW download, monitoring with web pages, datalogging and the alarms warning.
Features:
• 7 analog and 8 digital inputs
• 3 analog and 6 digital outputs
• Power supply 24 V AC and 110 V / 230 V AC
• Drives bipolar and unipolar electronic expansion valves
• SD / MMC card slot for easy software upload and datalogging
• Remote access to data through CANbus connection for additional display and keyboard
• RTC clock for managing weekly time programs and data logging information
• Ethernet / WebServer option
• Modbus RS485 opto-insulated serial interface
• Available with graphic LCD display for showing the desired information
• Dimensions 8 DIN modules
