Omron NX-TS2101 NX Series Temperature Input Unit

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.

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.
