G3CN-202PL1 DC5

Omron Automation and Safety
Solid State Photo-Coupled Relay (Photorelay) SPST-NO (1 Form A) 4-SIP
Active

Overview

The G3CN-202PL1 DC5 is a compact solid state relay in a 4-pin SIP package designed for AC load switching. It features photo-coupling for high isolation between the 5VDC logic-level input and the 75V to 264V AC power output. With a 2A load capacity and no moving parts, it provides a reliable, silent alternative to mechanical relays in space-constrained industrial and consumer applications.

Why Choose This Part

This SSR eliminates mechanical wear and contact bounce, significantly increasing the lifecycle of the switching circuit. The slim 4-SIP through-hole package saves PCB real estate while providing an easy interface for standard 5V logic controllers.

Applications

Solenoid and Valve Control
Switching small AC-powered pneumatic or hydraulic valves in industrial automation systems.
Small AC Motor Control
Managing low-power AC motors for fans, dampers, or circulation pumps in HVAC systems.
Home Appliance Logic
Interfacing low-voltage microcontrollers with high-voltage heating elements or pumps in consumer goods.

Getting Started

To use this component, ensure the input current is limited according to the 4 to 6VDC specification and provide adequate PCB copper for heat dissipation at the 2A load limit. Use a snubber circuit or varistor if switching highly inductive loads to protect the internal triac from voltage spikes.
