Pro External Controller
A Pro External Controller (PEC) runs a progressive cavity pump from your line's PLC or HMI instead of a front panel. Parameters are set and monitored over RS232C Modbus (ASCII, LRC), shot signals are answered without delay, and speed and channel can change while the line runs. It is a compact 24 V DC box. It works with PCP-005 through PCP-1000. The PEC-1000 adds a mix-ratio mode and a 5 A supply.
Compare models
| Model | Modes | Control | Supply | Pumps |
|---|---|---|---|---|
| PEC-100 | Time, Steady, Metering | PLC (RS232C Modbus) or HMI | 24 V DC, 3 A max | PCP-005 to PCP-1000 |
| PEC-1000 | Time, Steady, Mix Ratio | PLC (RS232C Modbus) or HMI | 24 V DC, 5 A max | PCP-005 to PCP-1000 |
How to choose
- If an operator sets up the pump at the station, a PROCON with its own touch screen is simpler.
- If the line PLC owns every setting and logs every shot, use a PEC.
