Product Overview

This analog input module converts field sensor signals into digital values for Modicon Quantum systems. It accepts standard process signals from pressure, temperature, and flow transmitters. The 140ARI03010C provides eight isolated input channels for reliable analog measurements. Its high-resolution conversion ensures precise process variable monitoring across all channels. This module significantly improves control accuracy in continuous process applications.

Technical Specifications

The 140ARI03010C measures 23.5 cm in height, 9.8 cm in width, and 14.5 cm in depth. It weighs approximately 0.95 kg, including all terminal blocks and mounting hardware. This module draws 360 mA from the +5 VDC backplane supply. It also requires an external 24 VDC supply for loop power, drawing 140 mA typical. The module features eight differential analog input channels with 16-bit resolution. It accepts standard 4-20 mA current signals with a range of 0 to 20 mA nominal. The module also supports 0-10 VDC voltage inputs through the same channel configuration. Its conversion time per channel measures 10 ms for all inputs simultaneously. The unit provides 2500 VAC optical isolation between field wiring and the backplane. Each channel includes a removable screw terminal block for simplified wiring access. The front panel features LED indicators for power and channel activity status.

Input Characteristics and Signal Processing

This module supports both 2-wire and 4-wire transmitter connections for installation flexibility. It applies digital filtering to eliminate high-frequency noise from sensor signals. The 140ARI03010C performs linearization and scaling for each input channel independently. Users can configure input ranges and alarm thresholds through the programming software. The module automatically detects open-wire conditions on each channel.

Physical and Electrical Parameters

Installation and Configuration Steps

Install the 140ARI03010C into any available slot within the Quantum I/O rack. Secure the module using the retaining screws at the top and bottom positions. Wire each field transmitter to its designated input channel with correct polarity. Connect the external 24 VDC supply to the loop power terminals for 2-wire transmitters. The module automatically begins signal conversion after system power-up. Configure input scaling and alarm settings through the programming software interface.

Typical Applications

This module monitors temperature sensors, pressure transmitters, and level transducers. It reads flow meters, pH sensors, and analytical instruments in process plants. The 140ARI03010C serves chemical, pharmaceutical, and food processing industries. Its eight-channel density suits applications requiring multiple analog measurements.
