PC-3000XC Controller

PC-3000XC Controller

The PC-3000XC controller is designed to operate up to 3 pumps in pump up or pump down applications. The controllers sequence pumps ON and OFF in response to a change in level input. The easy-to-read blue OLED display provides the operating status, featuring fast and intuitive menu navigation and setup. The PC-3000XC provides for advanced communication functionality for integration to open architecture telemetry/SCADA systems.

  • RS-485 terminal connections
  • Modbus RTU protocol
  • Designed to work with Pump Watch™ Express gateway remote monitoring system (default)
