PHASE LOSS, PHASE REVERSAL, PHASE UNBALANCE, UNDERVOLTAGE & OVERVOLTAGE PC SERIES WITH COMMUNICATION PC Series Three-Phase Monitor Relays protect equipment from voltage faults and communicate via Modbus TCP. This industry-leading technology makes data available for continuous monitoring, real-time alerts and intelligent troubleshooting of voltage systems. Real-time data improves decision making within modern control systems. This affordable IoT solution is advantageous in automation applications requiring protection of valuable three-phase equipment within a “smart” connected control system. Provides real-time status and measurement data via Modbus TCP Protects against phase loss, phase reversal, phase unbalance, undervoltage and overvoltage Compact 60 mm wide enclosure for both DIN-rail or screw mounting with extendable clips Wide voltage ranges to cover more global applications True RMS voltage measurement with full wave monitoring increases accuracy Full fault indication on front face for easy troubleshooting Pluggable terminal blocks simplify initial wiring and replacement 5A SPDT output contacts PC Series relays monitor three-phase system voltages to protect from damage due to phase loss, phase reversal, phase unbalance, undervoltage and overvoltage. These products detect single phasing, high, low and unbalanced voltages regardless of any regenerative voltages. Utilizing an advanced microprocessor-based design allows true RMS voltage measurement with full wave monitoring. This provides a more accurate method to measure the voltages, regardless of load type or wave shape. True RMS voltage measurement ensures accurate sensing in most generator and other applications with non-sinusoidal wave forms, eliminating nuisance tripping. A universal monitored voltage range of 190 to 600V AC covers more global applications. Dials allow adjustment of the undervoltage trip point, trip delay, restart delay, unbalance trip point, and selection of Line-to-Line system voltage. 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 installation and replacement, without having to remove any wires. Operation: When the proper three-phase line voltage is applied to the unit and the phase sequence (rotation) is correct, the relay is energized after the Restart Delay is completed. Any one of five fault conditions will de-energize the relay after the trip delay. As standard, re-energization is automatic upon correction of the fault condition. Manual reset is enabled by installing a momentary N.C. switch connected to terminals 5 & 6. A bi-color status LED indicates normal condition and provides specific fault indication to simplify troubleshooting. PROTECTS AGAINST Better.
