Industry leading technology to reduce downtime and service cost!

PC Series Three-Phase Monitor Relays protect your equipment from voltage faults and communicate voltage parameters via Modbus TCP.

This new technology from Macromatic makes real-time and historical data available for:

  • Continuous remote monitoring and real time alerts
  • Predictive and preventative maintenance
  • Intelligent troubleshooting

Communication improves decision making within smart network control systems. Protect motors and voltage-sensitive equipment in your smart connected control systems with this affordable IoT solution!

The Macromatic PC Series:

  • Provides real-time status and measurement data via Modbus TCP.
  • Protects equipment from damage due to phase loss, phase reversal, phase unbalance, undervoltage and overvoltage.
  • Detects single phasing, high, low and unbalanced voltages regardless of any regenerative voltages.
  • Provides more accurate sensing with True RMS voltage measurement.

A universal monitored voltage range of 190 to 600V AC covers more global applications. Knobs allow adjustment of the undervoltage trip point, trip delay, restart delay, unbalance trip point, and selection of Line-to-Line system voltage. Full fault indication on front face makes troubleshooting easy.

Dials allow adjustment of the undervoltage trip point, trip delay, restart delay and unbalance trip point. 

A 60 mm wide enclosure meets IEC Standards and mounts on 35 mm DIN-rail or on a panel with two screws inserted through extended clips on the back of the enclosure.

Pluggable terminal blocks on both the input and output side allow for easy initial wiring and replacement without having to remove any wires.
