Ordering Information
Important note for ordering:
Choose normally stocked products whenever possible to ensure availability that matches your schedule. Normally stocked items are
shown as shaded in the Ordering Information tables. Non-stocked items are available but may be subject to longer lead times. For the
most up-to-date information on stock status, contact your Omron representative.
J SINGLE PHASE MODELS
Omron's Power Controllers feature accessible settings and displays to simplify setup and monitoring. The power controller's soft-start
function gradually applies power to maximize the life of the load. All have plug-in replaceable power switching cartridges for fast servicing
so that wiring and settings are not disturbed.

Single-phase Models With continuous load current. All G3PX-jjjEC models incorporate terminals 11 and 12 for the current transformer (CT Unit), 13 and 14 for the external reset switch, and 16 and 17 for relay output as well as power/input terminals 1 through 10. - Page 5 *Impedance Load 2 Note: Two G3PX models can be connected in series to one OMRON Temperature Controller (with an internal impedance of 600 Ω) with a current output. 2. A Temperature Controller with an output of 7 to 20 mA is used with the G3PX to change the duty.
