Description

Designed for high-accuracy temperature monitoring within the Omron Sysmac platform, the NX-TS2101 serves as a 2-channel thermocouple temperature input module. This unit integrates into the NX Series I/O system, enabling precise thermal measurements for applications requiring tight temperature regulation. It supports the direct connection of multiple industrial thermocouple types, converting sensor inputs into digital values for real-time control.

The module features channel-to-channel isolation to prevent electrical interference and ground loops across process zones. Equipped with a high-density 16-point screwless push-in clamping terminal block, it simplifies field wiring and reduces installation times. Communication and synchronization are handled via the backplane, supporting free-run refreshing to maintain consistent signal updates.

Features

Two independent thermocouple input channels.
Broad thermocouple sensor support including K, J, T, E, L, U, N, R, S, B, WRe5-26, and PLII types.
High resolution of 0.1 degC maximum for standard sensors (0.2 degC maximum for R, S, and W types).
Fast conversion speed of 250 ms per unit.
Integrated transformer and photocoupler isolation between input circuits and the NX bus, as well as between individual input channels.
Screwless push-in clamping terminal block containing 16 connection terminals.
TS status indicator for clear operational diagnostics.

Applications

Plastic extrusion and injection molding thermal control systems.
Industrial ovens, kilns, and heat treatment furnaces.
Packaging machinery requiring precise heat sealing profiles.
Chemical processing and reactor thermal monitoring.
Food processing pasteurizers and storage systems.

Connections and Interfaces

Terminal Configuration	Function Description
Thermocouple Channel 1 (TC1)	Positive and negative thermocouple wire connection points
Thermocouple Channel 2 (TC2)	Positive and negative thermocouple wire connection points
Cold Junction Compensation (CJC)	Internal circuit references for cold-junction compensation

Installation Guidelines

Mount the unit on a standard 35 mm DIN rail alongside compatible NX Series CPU or communication coupler units.
Ensure correct thermocouple polarization when inserting leads into the screwless clamping terminals.
To achieve the stated conversion accuracy, allow the module to warm up for at least 30 minutes after power-up.
Route thermocouple extension cables away from high-voltage motor cables and power lines to reduce electromagnetic noise interference.

FAQ

Which thermocouple types does the NX-TS2101 support?

The NX-TS2101 supports K, J, T, E, L, U, N, R, S, B, WRe5-26, and PLII thermocouple types.

What is the measurement resolution of this module?

The module provides a resolution of 0.1 degC max. For R, S, and W sensor types, the resolution is 0.2 degC max.

Does this module require an external I/O power supply?

No, the NX-TS2101 does not consume or require external I/O power. It is powered via the NX bus interface.

Why is there a warm-up period specified for the NX-TS2101?

A 30-minute warm-up period is required to stabilize the internal electronics and the cold junction compensation circuit to guarantee accurate temperature measurements.
