The DPC-4F Duplex/Backup Controller is a multi-functional pump controller designed to operate two pumps. The controller can be configured to operate as duplex backup controller or as a duplex controller. The controller operated using inputs from 1-4 float switches.
Multi-Function
MODE 1: 1-float backup operation with pump run timer
MODE 2: 2-float backup operation
MODE 3: 3- or 4-float backup operation
MODE 4: 3- or 4-float duplex operation
Features
- Green LED indicators for Power On and Pump Call-To-Run
- Red LED indicator for Alarm and Backup Mode
- Amber LED indicators for Float Status
- Float out of sequence detection (Mode 4 only)
- HIGH level relay directly operated by FLOAT 4, independent of microcontroller
- 12 VDC power to float switches Relay Outputs: Pump Call-To-Run (2), Low, High, Horn/Backup
- UL Listed
