Schneider PC0085103 PLC Base Module

Technical Specifications

Physical Construction and Chassis Design

This PC0085103 PLC base module measures 11.4 inches in width. Its height reaches 6.9 inches with a depth of 3.2 inches. The total weight comes to approximately 3.12 pounds. Manufacturers constructed the chassis from painted steel for durability. Six module slots line up in a single horizontal row. Each slot accepts a standard Schneider I/O or CPU module.

Backplane Architecture and Signal Integrity

PC0085103 features a four-layer PCB backplane for clean signal routing. Two internal layers carry power while two handle data lines. Each slot uses a 64-pin DIN connector with gold-plated contacts. The slot pitch measures 1.5 inches from center to center. This spacing allows adequate airflow between installed modules. Consequently, the backplane minimizes cross-talk between adjacent high-speed cards.

Power Distribution and Energy Storage

The PLC base module provides two main power rails across all slots. The 5V DC bus delivers up to 8 amps for logic circuits. A separate 24V DC bus supplies 4 amps for field I/O power. Three 1500µF electrolytic capacitors sit on the input stage. These capacitors provide bulk energy storage for transient loads. Each slot also includes local decoupling capacitors for noise suppression. The PC0085103 distributes power evenly without voltage drops along the backplane.

Mounting Options and System Integration

You can mount this base plate either horizontally or vertically. Four threaded mounting holes secure it to a panel or rack. The PC0085103 operates reliably from 0°C to 60°C ambient. Passive convection cooling keeps the chassis temperature within limits. You will find this base module in Modicon PLC systems. For example, it holds processor cards, communication modules, and I/O adapters. Therefore, this unit provides a flexible foundation for factory automation controls.
