RK Series™ Single Phase Duplex 4-20mA Control Panel

Single Phase, Duplex 4-20mA Continuous Level Control System for Pump Control and System Monitoring

rk series single phase duplex 4-20mA control panel diagram

The RK Series™ Single Phase Duplex 4-20 mA continuous level sensing panel is designed to control two 115/230 VAC single phase pumps in water and sewage installations. The protective inner door features panel operating status indicators, LCD display, control buttons and provides access to the pump and control circuit breakers. The controller provides for alternation of the pumps for even usage. Panel is designed for 4-20mA input and 2-float backup control.
