Current Monitoring Relay

WTAIDQ Current Monitoring Relay integrates a solid-state switching module with SPDT AgCdO contacts and tool-free terminal blocks. This precision device incorporates start-up suppression, adjustable hysteresis calibration, built-in multi-voltage compatibility (24-480V AC/DC), dual-mode operation (auto/manual), and LED status visualization system. Engineered for industrial-grade adaptability, it delivers robust performance in motor control systems, automated production lines, and critical process instrumentation applications.

WTAIDQ Current Monitoring Relay features integrated shunt-based current metering with configurable latching/inhibit thresholds (0.5-30A programmable range), compliant with DIN/EN 60715 rail-mounting standards. This IEC 60664-certified device incorporates a tri-LED diagnostic system (relay state/alarm/power status) and provides proactive relay activation management through adaptive logic control, specifically engineered to prevent unintended relay actuation in industrial power distribution systems and motor control panels.

WTAIDQ Current Monitoring Relay delivers integrated current management via DIN-rail compliant installation, providing continuous single-circuit current surveillance and automated initiation of circuit transfer protocols upon over/undercurrent anomalies, ensuring critical load protection.

Our Current Monitoring Relay has an LED indicator. The green LED will on when power is applied to the input terminals, while the red LED blinks during a time-out and will turn ON when the output is energized.

Applications:

Designed for operational verification of rail switch heating systems, heat trace circuits, and single-phase motor loads with current flow monitoring.
