Omron NX-TC3408 Unité de contrôle de température série NX

Description

Precision thermal regulation within high-speed industrial environments is achieved using the Omron NX-TC3408, a multi-channel temperature control module designed for the Sysmac automation platform. Operating on the NX-series I/O system backplane, this unit provides 4 independent control loops with integrated thermocouple and resistance thermometer (RTD) inputs. It leverages 4 high-resolution analog outputs (0 to 20 mA or 4 to 20 mA) to deliver smooth, variable manipulated variable (MV) outputs for precise heat or cool control applications.

The unit features a rapid 50 ms conversion time per unit, ensuring fast response times in dynamic thermal systems. To simplify field installation and reduce panel assembly time, the NX-TC3408 is built with screwless Push-in Plus terminal blocks across two detachable connectors. This allows pre-wiring and simple swap-out maintenance, minimizing system downtime.

Features

• Four independent control loops for multi-zone thermal management.
• Universal temperature inputs supporting major thermocouples and Pt100/JPt100 RTDs.
• Four 14-bit analog current outputs configurable for 4 to 20 mA or 0 to 20 mA operation.
• Fast conversion rate of 50 ms per unit for high-speed tracking.
• Dual-zone control capabilities supporting both heating and cooling functions.
• Push-in Plus terminal connections for reliable, tool-free wiring.
• Detachable front I/O connector blocks for fast maintenance and installation.
• Seamless integration into EtherCAT or EtherNet/IP networks via NX-series coupler units.

Applications

• Plastic extrusion and injection molding machine barrel heating zones.
• Packaging machines requiring precise heat sealing bar regulation.
• Industrial ovens, drying chambers, and heat treatment furnaces.
• Semiconductor manufacturing equipment thermal control.
• Food processing and pasteurization temperature monitoring.

Technical Specifications

Connections and Interfaces

The unit features dual-tiered Push-in Plus terminal blocks. Connections are split across two independent, detachable terminal blocks to organize sensory input and control output wiring safely:

Installation Guidelines

• Mount the module securely onto a standard 35 mm DIN rail within a dust-free, dry control cabinet.
• Ensure that power to the NX-series bus coupler or controller is switched off before mounting or removing the module.
• To prevent electromagnetic interference (EMI) on sensitive RTD or thermocouple signals, route temperature sensor lines away from high-voltage motor and drive cabling.
• Maintain a minimum of 10 mm clearance around the module ventilation paths to prevent heat buildup.
