OMRON NX-TC3405 4-Channel Temperature Control Unit for NX Series

The OMRON NX-TC3405 (NX-TC3405) is a multi-channel temperature control unit engineered for use with OMRON NX-series modular I/O systems and automation controllers. Designed to deliver stable and responsive thermal regulation within distributed machine architectures, this module incorporates four independent thermocouple input channels and four dedicated PNP outputs. By handling closed-loop temperature management directly on the local I/O rack, the unit offloads intensive processing tasks from the primary central controller and reduces communication overhead across industrial networks. Operating as an integral part of the NX platform, the NX-TC3405 links seamlessly with compatible bus couplers and controllers, enabling precise setpoint tracking, fast response times, and straightforward diagnostics. Its thermocouple-compatible inputs accommodate standard sensor arrangements, making the module suitable for packaging machinery, molding equipment, heat treatment systems, and process heating environments requiring compact footprint installations and multi-zone thermal management.
