Schneider Modicon Micro 110CPU31103 Programmable Controller

Description

The 110CPU31103 is a high-performance, all-in-one micro programmable logic controller (PLC) from the Schneider Electric Modicon Micro automation range. This compact, integrated unit combines a central processing unit, a 24 VDC power supply, and a fixed configuration of discrete DC inputs and solid-state DC outputs into a single, ruggedized enclosure. Designed for standalone machinery and localized control loops, the 110CPU31103 provides deterministic execution of ladder logic, ensuring reliable operation in space-constrained industrial environments.

Features

• Integrated CPU, power supply, and I/O in a single compact module.
• 16 discrete 24 VDC inputs and 12 solid-state DC transistor outputs.
• Built-in Modbus serial communication port (RS-232C/RS-485) for HMI or drive integration.
• Non-volatile EEPROM and battery-backed RAM for secure logic and data retention.
• High-speed processing with 0.5 ms per kiloword execution time.
• Front-facing LED matrix for real-time status monitoring of I/O, Run, and Fault states.

Applications

The Modicon Micro 110CPU31103 is suitable for a wide range of industrial automation tasks, including:

• Water pumping and treatment stations.
• Material handling and conveyor control systems.
• Automated packaging machinery.
• Minor power generation and distribution control.
• Distributed machine-level control loops.

Technical Specifications

Installation Guidelines

• Ensure the controller is mounted in a clean, dry, and vibration-free environment.
• Maintain adequate clearance around the unit for ventilation and heat dissipation.
• Always disconnect power before installing or removing wiring to prevent electrical shock or damage to the module.
• Use shielded cables for communication and I/O signals to minimize EMI interference.
• Ensure proper grounding of the module chassis to the control panel backplane.
• Observe correct polarity when connecting the 24 VDC power supply.

Compliance and Certifications

The 110CPU31103 meets international standards for industrial safety and performance, including CE, UL, CSA, and FM Class 1 Division 2 certifications.

FAQ

What is the primary communication protocol for this CPU?

The 110CPU31103 features an integrated Modbus serial port, which supports standard RS-232C or RS-485 communication for connecting HMIs, VFDs, or programming terminals.

Is this module expandable?

No, the 110CPU31103 is designed as a non-expandable, all-in-one micro PLC architecture, providing a fixed I/O count for compact applications.

How is the logic protected during power loss?

The unit utilizes a combination of non-volatile EEPROM and battery-backed RAM to ensure that logic maps, registers, and operational counters are preserved during power outages.
