Schneider PC0984385 Modicon PLC Peripheral Module for Quantum Systems

The Schneider PC0984385 provides additional communication ports for Modicon Quantum PLCs. You can install this module directly into any standard Quantum rack slot. It expands the CPU’s connectivity for programming and HMI devices. This module suits multi-device network architectures.

Technical Specifications and Hardware Layout

The Schneider PC0984385 measures 138 mm in height. Its width reaches 54 mm, and the depth equals 145 mm. The Schneider PC0984385 weighs approximately 0.30 kilograms. A single internal PCB holds all interface and isolation circuits. The module contains no energy storage capacitors or batteries. Two 9-pin D-sub connectors provide RS-232 and RS-485 ports. One 48-pin edge connector interfaces directly with the Quantum backplane. Three status LEDs indicate power and port activity.

Communication Specifications and Performance

The Schneider PC0984385 supports baud rates from 300 to 115.2 kbit/s. It works as a Modbus master or slave on both ports simultaneously. This module handles data lengths of 7 or 8 bits with various parity options. Consequently, it connects programming terminals, HMIs, and drives easily. The RS-232 port supports point-to-point connections up to 15 meters. The RS-485 port allows up to 32 devices on a multi-drop network. Galvanic isolation separates the communication ports from the backplane logic.

Installation and Diagnostic Features

You must insert the Schneider PC0984385 firmly into a standard Quantum rack slot. Transitioning to wiring, use shielded serial cables for noise immunity. Three front LEDs show power, transmit, and receive activity clearly. A DIP switch block sets the port parameters for easy configuration. Always power off the PLC before removing or inserting the module. The operating temperature range spans from 0°C to 60°C reliably.
