Configured for resistance thermometer measurement loops within industrial backplane architectures, the Omron NX-TS2201 (NX-TS2201 Temperature Input Unit) provides direct physical/electrical execution.

Model Suffix Breakdown & Functional Design

The part number denotes specific structural attributes: "TS" designates a Temperature Input module, "2" indicates 2 input channels, "2" specifies Resistance Thermometer sensor compatibility, and "01" defines a conversion time of 250 ms per unit, a maximum resolution of 0.1 deg C, and Free-Run backplane refreshing.

Hardware Specifications

Backplane Bus & Network Synchronization

Backplane bus communication velocity and I/O density scaling preserve continuous data transfer across local expansion nodes without introducing timing skew. Photocouplers handle signal isolation between inputs and the internal NX bus, while transformers isolate power lines. Firmware flash compatibility ensures long-term operational consistency during controller software upgrades across deterministic networks.

• 1 x Screwless Clamping Terminal Block (16 terminals)

• 1 x Installation Leaflet

Field Installation Guidelines

• Mount the module securely onto a standard 35 mm DIN rail inside a protective industrial control enclosure.

• Terminate three-wire Pt100 or Pt1000 RTD leads directly into the 16-terminal screwless clamping block.

• Keep conductor resistance below 20 ohm to restrict measurement distortion to 0.06 deg C/ohm max.

• Observe a mandatory 10-minute warm-up duration following power-up to stabilize internal reference circuits.
