Overview

The PUA01CD48500V is an 11-pin plug-in monitoring relay designed for high-voltage AC and DC systems. It offers versatile monitoring for both over-voltage and single-phase current, operating on a 24 to 48 VAC/DC supply voltage. The device provides a measurement range from 50 to 500V and includes an 8A SPDT relay output for system protection.

Why Choose This Part

The plug-in housing simplifies maintenance by allowing rapid replacement without rewiring terminal blocks. Its wide 50 to 500V AC/DC measurement range makes it a versatile stock item for various industrial power monitoring requirements.

Applications

High-Voltage Monitoring
Sensing voltage fluctuations in 500V AC or DC power distribution lines to prevent equipment damage.
Industrial Pump Protection
Monitoring single-phase motor current to detect dry-run or locked-rotor conditions.
UPS System Oversight
Verifying battery bank or inverter output voltage levels within 24-48V control environments.
Process Automation
Integrating with PLC systems via SPDT relay contacts to trigger alarms when electrical thresholds are exceeded.

Getting Started

Mount the device using a standard 11-pin circular socket such as the Carlo Gavazzi ZRE11 or similar DIN-rail mount base. Configure the threshold settings and hysteresis using the front-facing potentiometers to match your specific system protection requirements. Ensure the supply voltage is between 24 and 48 VAC/DC and verify the load does not exceed the 8A relay rating.
