ABB IMDER02 | Bailey INFI 90 Digital Exchange Repeater Module

Product Description

Overview

The IMDER02 is a digital communication repeater module from ABB, designed for Bailey INFI 90 and Network 90 Distributed Control Systems (DCS). It ensures reliable data transmission over long distances by regenerating and amplifying digital signals. This module is essential for maintaining signal integrity and expanding the reach of industrial communication networks.

Key Features and Advantages

Signal Regeneration and Amplification

• Restores weakened digital pulses to their original strength and timing.

• Ensures accurate data transmission across long cable runs and complex networks.

Network Extension Capabilities

• Supports network segments up to 4,000 meters, depending on cable type and communication protocol.

• Accommodates up to 32 devices per segment, enabling additional I/O modules and field instruments.

Electrical and Optical Isolation

• Provides optical isolation between segments to prevent ground loops and high-voltage surges.

• Shields the network from electromagnetic interference (EMI) in industrial environments.

Reliability and Maintenance

• Hot-swappable design allows replacement without shutting down the DCS.

• Front-panel LED indicators display real-time status and fault conditions.

• Rack-mounted configuration simplifies installation and integrates with standard Bailey cabinets.

Enhanced Remote I/O Features

• Supports multiple protocols, including Modbus TCP and RTU over TCP.

• Ethernet interface with 10/100 Mbps data transfer.

• Surge and reverse polarity protection for stable operation in harsh conditions.

• DIN rail mountable with compact IP30-rated enclosure.

• Galvanic isolation for analog channels and 2 kV isolation for digital inputs.

Technical Specifications

Applications

• Signal extension for INFI 90 or Network 90 DCS networks

• Connection of geographically dispersed I/O modules, sensors, and actuators

• Protection against ground loops and EMI in industrial plants

• Hot-swappable communication module for continuous process operations
