Omron NX-TC3406 Temperature Controller

The Omron NX-TC3406 is an advanced 4-loop temperature control unit for NX-series distributed I/O systems, designed to deliver ultra-precise thermal regulation with real-time response and integrated signal isolation. Supporting a wide range of sensor inputs—including thermocouple and Pt100/Pt1000 RTD types—and providing 4 independent PNP digital outputs, this controller is ideal for machine builders and process automation applications that demand tight thermal stability.

Equipped with screwless Push-in Plus terminals for fast wiring and integrated into the NX I/O Bus, the NX-TC3406 ensures seamless EtherCAT-based control and synchronisation in Omron Sysmac environments.
