Schneider 140NOA61100 Module InterBus Communication for Quantum PLCs

The Schneider 140NOA61100 connects Quantum PLCs to InterBus fieldbus networks. You can install this module directly into any standard Quantum rack slot. It bridges the internal backplane with high-speed InterBus communication systems. This module suits factory automation and process control applications.

Technical Specifications and Hardware Layout

The Schneider 140NOA61100 measures 138 mm in height. Its width reaches 54 mm, and the depth equals 145 mm. The Schneider 140NOA61100 weighs approximately 0.34 kilograms. A single internal PCB holds all bus interface and isolation circuits. The module contains no energy storage capacitors or batteries. One 9-pin D-sub connector provides the InterBus interface. A 48-pin edge connector interfaces directly with the Quantum backplane. Four status LEDs indicate power, communication, and error conditions.

Communication Performance and Addressing

The Schneider 140NOA61100 supports InterBus baud rates up to 2 Mbit/s. It handles up to 64 slave devices on a single network segment. This module transfers 64 bytes of input and 64 bytes of output data per scan. Consequently, it supports medium-sized distributed I/O networks effectively. You can set the station address using a DIP switch block. Valid addresses range from 1 to 254 for flexible network integration. Galvanic isolation separates the InterBus side from the backplane logic.

Installation and Diagnostic Features

You must insert the Schneider 140NOA61100 firmly into a standard Quantum rack slot. Transitioning to wiring, use shielded InterBus cables for optimal noise immunity. The module includes built-in termination resistors for end-of-line configuration. Four front LEDs show bus communication status, power, and module health. A watchdog timer resets the communication after 500 ms of inactivity. The operating temperature range spans from 0°C to 60°C reliably.
