Impulse Relays

GFC1-25T series lmpulse relay, the contact switching current can reach 25A. The coil is triggered by apulse signal to change the state of the contact; The product has two stable mechanical positions, andthecontact will open when the next pulse comes. Each received pulse will reverse the position of thecontact.Compared with the common relay, which needs to be continuously energized when the armatureis closed,ithas the characteristics of low power consumption.

Product Description

●Introduction

1. Key Features
● Rated Current: 25A (Inductive Load)
● Coil Voltage: Typically available in 12V/24V DC or 110V/220V AC/DC (varies by model)
● Operation Type: Bistable (Latching) – Maintains state without continuous power
● Switching Mechanism: Pulse-triggered (Single-coil design)
● Mechanical Life: ≥100,000 operations (Industrial-grade durability)
● Contact Configuration: SPDT or DPDT (depending on variant)
2. Working Principle
● Pulse-Driven Activation: A short-duration (≥20ms) voltage pulse toggles the relay state.
● No Holding Current: Remains in last position after pulse removal (energy-efficient).
● Fail-Safe Design: Resistant to power interruptions.
3. Typical Applications
● Motor Control – Forward/Reverse switching
● Energy Meters – Remote load switching
● Automation Systems – State retention in PLC circuits
● Power Distribution – Automatic transfer switching (ATS)
The product can implement the remote control circuit and control the lighting circuit through theconversion of contacts. The composition of the circuit is as follows:
● Incandescent lamp, Halogen lamp, etc.(resistive load)
● Fluorescent lamps, Discharge lamps, etc. (inductive load)
