Omron G3PC DATASHEET

Solid State Relays with Failure Detection Function

G3PC

Detects failures in SSR used for heater
temperature control and simultaneously
outputs alarm signal. This SSR supports the
safe design of heater control systems, and
contributes to maintenance improvements
by the user.

• Main detection items:
SSR short-circuits and SSR open-circuits

• Alarm output possible to NPN/PNP-input devices.

• The failure-detection function is built-in and power is supplied
from the main circuit power supply making wiring simple.

• Slim design (width: 22.5 mm) incorporating a heat sink.

• In addition to screw mounting, DIN track mounting is also
possible.

• Certified by EC, UL, and CSA.
