MATelec HydroWHIZ FPC-63243-(AA-D)/IOT Mild Steel IP56 Inner Door 3PH 1.6-13A DOL Dual Pump Controller

The MATelec FPC-63243-(AA-D)/IOT combines 400Vac three-phase dual-pump control with IoT connectivity for communication with the Propitect IoT platform. The powder-coated mild steel housing features an inner door that isolates power and control components, a removable gland plate, and a pad-lockable mains power isolator switch. Wear balancing is managed by a duty sharing algorithm that rotates the duty pump based on run hour logs to equalise pump usage.

Designed for a 400Vac supply, the control board governs pump contactors to activate the motors safely. Individual pump protection is provided by standard thermal overloads rated for 1.6-13A, providing thermal overload protection. Low-voltage control circuits operate on a circuit-breaker protected 24Vdc supply, isolating field float switches from high-voltage supply lines.

The module handles distinct pumping types, regulating level empty wet wells, pressure boosting, or temperature control. The control board receives an analogue 4-20mA transducer input alongside up to eight digital inputs for float switches, pressure switches, or thermostats. Multi-pump staging uses a 3-second staggered start delay and a 1-second staggered stop delay to prevent excessive current draw and reduce water surge or water hammer.

The colour touchscreen HMI on the inner door displays real-time system status, logged data, date-stamped historical faults, and analog trend graphs. System faults trigger an integrated visual strobe and a mutable buzzer alarm, with a mute function. An onboard IoT module provides communication with the Propitect IoT platform for remote monitoring. System protective routines integrate transducer failure protection, cycle count limits, high and low level protection, and a 7-day pump anti-seize program.
