NX-TC3406 4-Channel Temperature Control Unit TC/Pt100 PNP SSR | Omron

The Original New Omron NX-TC3406 is a 4-channel temperature control unit for the NX series I/O system, designed to provide precise heat or cool control for industrial heating and cooling applications. Each of the 4 isolated inputs supports thermocouple or Pt100 sensors, while 4 PNP voltage outputs drive external SSRs. With a 50 ms conversion time and free-run refreshing, this module delivers reliable temperature regulation for packaging machinery, injection molding, and food processing equipment. The 24 mm wide unit uses screwless Push-in Plus terminals for tool‑free wiring. Part of the NX series for EtherCAT and EtherNet/IP communication coupler systems.
