Module Specifications

Precision Signal Acquisition & Network Performance

The module processes field temperature measurements through high-precision conversion stages without drawing power from the I/O bus supply line. Dynamic channel-to-channel isolation safeguards analog integrity against ground loops, while firmware flash compatibility ensures uniform sensor calibration tables across distribution nodes. Real-time process data is seamlessly transferred across backplane bus communication velocity Licences, maintaining system performance alongside high-density I/O density scaling.

Factory Package Content

• 1 x NX-TS2202 Temperature Input Unit
• 1 x 16-Pin Push-In Screwless Terminal Connector
• 1 x Module Installation Reference Guide Sheet

Field Mounting & Cable Termination

DIN Rail Mounting

• Mount the module vertically onto a standard 35 mm DIN rail until the rear DIN rail hook locks securely.
• Ensure 30 mm of vertical space above and below the module housing to allow natural air circulation.

Field Cable Wiring

• Strip Pt100 RTD leads to the specified insertion length and insert them directly into the push-in clamp terminals.
• Utilize three-wire shielded cables for Pt100 connections to eliminate line resistance offset errors up to 20 ohm max.

Technical Inquiry Resolutions

• What temperature sensor type is supported by the NX-TS2202?

  The unit is engineered exclusively for 3-wire Pt100 resistance temperature detectors (RTDs).

• What is the sampling conversion rate of the analog input circuitry?

  The module executes internal signal conversion at a fixed rate of 10 ms total per Unit.

• How are individual analog channels isolated from each other?

  Individual channels feature galvanic isolation via digital isolators for signals and transformers for power.

• Does the unit consume current from the field I/O power supply?

  No current is drawn from the I/O power supply line as the module operates without I/O power supply terminals.

• What is the maximum resolution provided for temperature readings?

  The unit delivers high-precision temperature measurements with a maximum resolution of 0.01 deg C.

• How long is the recommended warm-up period after powering on?

  A minimum warm-up period of 30 minutes is required to achieve full conversion accuracy.

• What terminal block style is utilized for sensor wiring?

  The module features a detachable 16-point screwless clamping push-in terminal block.

• Can module replacement be performed while backplane power is active?

  Backplane power must be isolated before removing or installing the module to prevent equipment damage.
