Technical Overview

The Omron G3PE-225B DC12-24 is an industrial-strength, single-phase solid-state relay (SSR) designed specifically for highly demanding heater control applications. Operating with a low-voltage DC input (12-24 VDC), it seamlessly switches AC loads up to 25A across a 100-240 VAC operational range. Engineered with a reliable phototriac coupler and zero-crossing capability, this relay drastically limits noise generation, EMI, and transient surges upon switching. It features a factory-integrated heat sink to ensure superb thermal management and consistent performance in ambient temperatures ranging from -30°C to +80°C. Its compact 22.5 mm slim profile maximizes valuable control panel space, permitting high-density mounting on DIN rails or via screw panels, making it an ideal, maintenance-free solution for fast-cycling industrial automation.

Key Features

  • Compact 22.5 mm slim profile design maximizes available panel space.
  • Integrated heat sink provides superior thermal dissipation without external cooling components.
  • Zero-crossing function reduces electrical noise and limits transient surges during switching.
  • Built-in LED status indicator allows for immediate visual monitoring of operation.
  • Improved surge dielectric strength of 2500 VAC for output circuits.
  • Maintenance-free solid-state construction eliminates contact bounce and mechanical wear.
  • Flexible mounting options supporting both DIN track and direct panel screw mounting.
  • RoHS compliant and fully conforms to UL, CSA, and EN (TÜV) international standards.
