Omron, G3PF Series

Heater Burnout Detection

• Built-in Current Transformer (CT) helps reduce wiring steps.

• Detects the burnout of any one of a group of heaters.

• Detects the burnout of 3-phase heaters.

• Detects SSR short-circuit failures.

• Error detection level can be easily set with a switch.

• Mounts to a DIN track or with screws.

• Three types of input terminals available: M3 terminals, screwless clamp terminals (detachable), or compact slotted screw terminals (detachable).

• Certified for CSA and EN (TÜV).

• The G3PF-2[][]B-[][][] Series is UL certified.
