Product catalog summary
General Information
This document provides technical specifications and operational guidelines for automation components, focusing on electrical and mechanical features, as well as monitoring and sensing relays.

Electrical Features
  • Two potential-free change-over contacts with a rated operating current of 5A at 250V AC.
  • Rated voltage output circuit of 250V AC and surge voltage of 4kV.
  • Control frequency ranges from 48 to 63 Hz.
  • Mechanical life expectancy is 20 million operations, while electrical life is 200,000 operations at 1000 VA resistive load.
  • Equipped with two LED indicators for monitoring voltages across various terminals.

Mechanical Features
  • Operational temperature range from -25°C to +55°C, with storage and transport conditions from -25°C to +70°C.
  • Dimensions: 22.5mm width, housed in self-extinguishing plastic with IP40 protection.
  • DIN rail mounting with shock resistance of 15g for 11ms.
  • Terminal capacity varies based on cable type and size.

Phase Monitoring
  • Phase Sequence Monitoring: Detects changes in phase sequence, switching output relays to off-position if a change is detected.
  • Phase Failure Monitoring: Output relays switch to off-position if one of the three phases fails.

Sensing and Monitoring Relays
  • Includes phase sequence, phase failure, under voltage, window function, asymmetry monitoring, and loss of neutral wire detection.
  • Specific models (GHPMSY20) require additional power modules (TR2) with varying voltages.

Voltage Monitoring
  • Under Voltage Monitoring: Triggers a delay when voltage falls below a set value, switching relays off after the delay.
  • Window Function: Relays switch on when voltage exceeds a minimum set value and off when it exceeds a maximum set value, with delays for both transitions.

Asymmetry Monitoring
  • Monitors phase-to-phase voltage asymmetry, triggering a delay if asymmetry exceeds set values, leading to relay switch-off.
  • Loss of neutral wire is detected as asymmetry, with similar delay and switch-off mechanisms.
