What does this module do in a Modicon Quantum PLC system?

It is an analogue input module designed for temperature measurement using RTD sensors. It provides 8 differential input channels and converts RTD signals into digital values for the PLC to read.

Which sensor types are supported?

It supports RTD temperature probes including Pt 100, Pt 200, Pt 500, Pt 1000 and Ni 100, Ni 200, Ni 500, Ni 1000, depending on the selected measurement range and excitation mode.

How many input channels are available and what does 'differential' mean here?

There are 8 analogue input channels, each using differential measurement. Differential inputs measure the voltage difference between two terminals per channel, which helps reduce sensitivity to common-mode noise compared with single-ended measurement.

What measurement resolution can I expect?

The module provides 13-bit analogue input resolution for its RTD measurement functions.

What wiring configurations are supported for RTD sensors?

It supports 2-wire, 3-wire, and 4-wire RTD wiring. The chosen wiring method affects performance and update time.

What is the typical update time for readings?

Update time is 640 ms for 2-wire/4-wire RTD wiring and 1200 ms for 3-wire RTD wiring.

How is this module addressed in the PLC (memory/words)?

It requires 9 input words for addressing within the PLC configuration.

What built-in diagnostics or fault detection does it provide?

It supports fault detection including broken wire and overtracking scale conditions, helping identify wiring issues or out-of-range measurements.

What local indicators are on the front of the module?

It includes LED indication for bus communication (Active), an external fault indicator, and per-channel LEDs showing channel on status and channel fault status (8 green and 8 red for the channels).

What is the bus current requirement and power dissipation?

Bus current requirement is 200 mA, and typical power dissipation is 1 W.

What isolation levels are provided?

Isolation between channels and bus is rated at 1780 V AC (47–63 Hz) for 60 seconds and 2500 V DC for 60 seconds. Isolation between channels is 300 Vrms AC.

What environmental conditions is it designed to operate in?

Operating ambient air temperature is 0–60 °C, storage temperature is -40–85 °C, relative humidity is up to 95% (non-condensing), and operating altitude is up to 5000 m.

Where can it be installed in a Quantum rack?

It can be mounted in any slot in a Modicon Quantum rack, allowing flexible placement alongside other I/O modules.

What terminal block or connector is used for field wiring?

The specified connection type is 140XTS00200, which is the terminal assembly used for wiring RTD inputs to the module.

What are the physical size and weight considerations for panel layout?

The module is a standard-format Quantum module with approximate dimensions of 250.0 mm (height) x 103.9 mm (width) x 40.3 mm (depth). Net weight is approximately 0.3 kg (for reference: Schneider 140ARI03010).
