Omron NX-TS3104 NX Series Temperature Input Unit

Description

Designing precise thermal monitoring loops within modular PLC architectures requires reliable and high-resolution instrumentation, which the Omron NX-TS3104 temperature input unit delivers. This module interfaces directly with the Omron NX-series Sysmac controller or EtherCAT Communication Coupler Units to transmit high-accuracy temperature data across the backplane. Utilizing independent delta-sigma analog-to-digital conversion, it supports up to four thermocouple inputs with a resolution limit of 0.001 degC. Standard Free-Run refreshing matches synchronous system cycle times, while comprehensive channel-to-channel and channel-to-bus galvanic isolation protects internal processing logic from hazardous industrial field voltage spikes.

Features

• Four independent thermocouple input points per module.
• Fast conversion speed of 60 ms per Unit for responsive control loops.
• Exceptional measurement resolution up to 0.001 degC max.
• Broad sensor compatibility, supporting K, J, T, E, L, U, N, R, S, WRe5-26, and PLII thermocouples.
• Dual-stage electrical isolation utilizing integrated power transformers and digital signal isolators between inputs and the internal NX bus, as well as channel-to-channel.
• Toolless wiring via dual 16-point screwless clamping terminal blocks.

Applications

• Plastic extrusion and injection molding temperature control zones.
• Industrial heat treatment furnaces and annealing kilns.
• Packaging machinery sealing-jaw thermal management.
• Food processing, pasteurization, and sanitization loops.
