PLCs, Power Supplies & Others

Product Overview

This CPU module serves as the central processing unit for Schneider’s compact automation systems. It executes control programs and manages I/O data exchange with high reliability. The PC0984131 provides a cost-effective processing solution for small to medium applications. Its compact housing integrates easily into space-constrained control panels. This processor supports both discrete and analog control tasks effectively.

Technical Specifications

The PC0984131 measures 16.5 cm in width, 12.0 cm in height, and 13.5 cm in depth. It weighs approximately 1.8 kg, including the integrated power supply unit. This module draws 500 mA from the 24 VDC input supply under normal operation. It features 16 discrete inputs and 12 discrete outputs integrated directly on the base unit. The CPU includes one RS485 communication port for programming and monitoring access. Its internal memory stores up to 8,000 instruction words for application programs. A supercapacitor retains program data for approximately 72 hours during power loss. The processor executes basic logic instructions in 2.5 ms for consistent scan times. It supports up to 24 expansion I/O modules for system growth. The front panel provides LED indicators for power, run, and diagnostic status.

Processing Architecture and Expansion

This CPU executes user programs written in ladder logic and instruction list formats. It scans inputs, processes logic, and updates outputs during each program cycle. The PC0984131 accommodates both local and remote I/O through its expansion interface. Users can monitor program execution and modify parameters through the communication port. The processor includes built-in self-diagnostics for fault detection and system protection.

Physical and Electrical Parameters

Installation and Configuration Guidelines

Mount the PC0984131 vertically on a flat panel surface using the four mounting screws. Connect the 24 VDC power source to the designated terminal block positions. Wire field devices to the integrated input and output terminals accordingly. Connect the programming cable to the RS485 port for software access. Download the user application through the programming interface after configuration. The CPU automatically executes the program when you select the RUN operating mode.

Typical Applications

This CPU controls packaging equipment, conveyor systems, and small assembly machines. It manages pumping stations, fan controls, and material handling conveyors effectively. The PC0984131 also serves HVAC systems and building automation applications. Its integrated I/O reduces component costs in basic control installations.
