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.

FAQ

What thermocouple types are compatible with the Omron NX-TS3104?

The NX-TS3104 supports a wide range of standard industrial thermocouples, including types K, J, T, E, L, U, N, R, S, WRe5-26, and PLII.

Does the NX-TS3104 feature channel-to-channel isolation?

Yes, it provides dual-stage isolation (transformer power and digital signal isolators) both between individual input channels and between the inputs and the internal NX bus.

Why is there a warm-up period specified for this unit?

A warm-up period of 45 minutes is required for the internal reference junction compensation circuits to stabilize and achieve the module's rated temperature measurement accuracy.

What is the maximum measurement resolution of the NX-TS3104?

The module offers a maximum high-precision resolution of 0.001 degC.
