The new microcontroller based MPRCC is a multistage electronic capacity controller for multicylinder reciprocating compressor or rack systems.
LCD Based unit has easy to use settings, like Set point -Low pressure (LP), Neutral Zone (NZ), Inter-stage differential (ISD) & Interstage timer.
One Analog input ( 4 to 20mA) for pressure transmitter e.g. compressor suction or RTD Pt100
One Digital input (potential free) for Compressor on feedback Four / Six Relay Output for Compressor Capacity Control Solenoid Valves and Compressor trip Adjustable time delay for capacity control solenoid valves Adjustable Neutral Zone, Inter Stage Differential, Calibration
• Optional RS232 / RS485 port for communication
• Optional available Software for PC monitoring
