Product Details

MODICON 140ARI03010 is a reliable analog input module built for the Modicon Quantum PLC platform. This analog input collects continuous analog signals from field signal transducers such as temperature transmitters, pressure sensors and flow senders, and converts these analog readings into digital data readable by the Quantum CPU for process monitoring and closed-loop control. It supports multiple configurable signal ranges including voltage and current signals commonly used in industrial instrumentation. The module communicates with the rack controller through the Quantum backplane bus and sends converted digital values for PID regulation, data logging and alarm triggering. Each channel provides overvoltage and overcurrent protection to shield internal circuits from unexpected field surges. LED indicators on the front panel display module status, channel faults and bus activity, allowing technicians to quickly locate abnormal sensors or wiring faults on site. Integrated EMI suppression circuits reduce interference caused by nearby variable frequency drives and contactors, maintaining stable signal sampling in noisy factory environments. Users can set channel type, scaling and filtering parameters via Unity Pro configuration software. As a widely used industrial spare part, it is frequently used for system replacement and upgrade of existing Modicon Quantum control racks. Direct drop-in replacement preserves original sensor wiring, scaling setup and control logic, and effectively cuts system debugging and production downtime.
