TheABB IMDER02is a Digital Exchange Repeater (DER) module within the Infi 90 and Symphony Harmony series. It is specifically designed to extend the physical distance and reliability of the control system's communication bus by regenerating and retiming digital signals, ensuring that data integrity is maintained across long cable runs in sprawling industrial facilities.
Specifications
Signal Type: Processes high-speed digital communication signals for the Infi-Net or Plant Loop.
Input/Output Ports: Dual-channel design for bidirectional signal repetition and amplification.
Transmission Distance: Significantly extends the allowable distance between system nodes beyond standard copper limits.
Propagation Delay: Ultra-low latency design to minimize timing jitter in time-sensitive control loops.
Power Supply: Powered via the standard Infi 90 backplane, typically utilizing +5 VDC logic power.
Isolation: Features high-level galvanic isolation to protect against ground loops and transient voltage spikes.
Mounting: Occupies a single slot in a standard Module Mounting Unit (MMU).
Features
Signal Regeneration: Cleans and reshapes distorted digital pulses to prevent data corruption over long distances.
Network Expansion: Allows for flexible plant topologies by linking remote cabinets to the central control room.
Redundancy Support: Compatible with redundant bus architectures to ensure continuous operation in the event of a cable fault.
Automatic Gain Control: Adjusts signal strength dynamically to compensate for varying cable lengths and qualities.
Diagnostic LEDs: Equipped with front-panel indicators that show traffic flow and signal quality for both channels.
Maintenance-Free Design: Solid-state circuitry with no moving parts, built for 24/7 operation in harsh electrical environments.
