Omron NX-TS2201 NX Series Temperature Input Unit

Description

Designed for precise thermal data acquisition in automated industrial environments, the NX-TS2201 delivers high-resolution temperature monitoring within the Omron Sysmac platform. This high-density temperature input unit supports up to two resistance thermometer (RTD) input points, processing signals from Pt100 and Pt1000 three-wire sensors. Utilizing a fast conversion cycle of 250 ms per unit and achieving a thermal resolution of 0.1 degC, it ensures stable and accurate process variables for critical control loops.

The module is built on the NX-series I/O platform, interfacing directly with NX-series CPU Units or Communication Couplers over EtherCAT or EtherNet/IP networks. To ensure high signal integrity in noisy electrical environments, the unit incorporates comprehensive galvanic isolation between individual inputs and the internal NX bus, alongside channel-to-channel isolation. Connection to field sensors is simplified through a high-reliability, 16-terminal screwless clamping terminal block.

Installation Guidelines

• Mounting: Install on standard 35 mm DIN rail (IEC 60715) alongside other NX-series hardware. Ensure correct interlocking of bus connectors.
• Warm-up Period: Allow at least 10 minutes of active operation after power-up for the internal circuitry to stabilize and achieve rated measurement accuracy.
• Wiring: Use shielded twisted-pair cables for sensor lines. Connect the shield securely to avoid electromagnetic interference from adjacent high-voltage wiring.
• Terminal Tooling: Use the dedicated flat-blade screwdriver or equivalent tool to actuate the screwless clamps when inserting or removing conductor wires.
