ABB RLM02 PROFIBUS DP/FMS Redundancy Link Module Brand New

Overview

The ABB RLM02 PROFIBUS DP/FMS Redundancy Link Module is designed to enhance the reliability of PROFIBUS communication by converting a non-redundant PROFIBUS line into two redundant RS485 lines or vice versa. This module supports seamless integration into PROFIBUS networks, allowing for robust and fault-tolerant data communication.

Key Features

• Conversion of PROFIBUS Lines: Transforms a single, non-redundant PROFIBUS line into two mutually redundant lines (A and B) or vice versa.

• Versatile Positioning: Can be installed directly after a master, before a bus segment with multiple slaves, or before an individual slave.

• Interface Support: Each RLM02 PROFIBUS interface supports up to 31 PROFIBUS stations.

• Redundant Couplers Integration: Compatible with PROFIBUS stations equipped with redundant couplers.

• Extendable Network: Allows the use of repeaters and media converters to extend the PROFIBUS line length and increase the number of connected stations.

Specifications

• Use: Applicable for PROFIBUS DP/FMS lines

• Line Conversion: Converts non-redundant line to redundant lines A/B and vice versa

• Automatic Line Selection: Automatically selects between redundant lines

• Transmission Rate: 9.6 kbit/s to 12 Mbit/s

• Communication Monitoring: Monitors communication for errors and status

• Repeater Functionality: Includes repeater capabilities

• Wire Cross Section: 8-pin terminal strip, up to 1.5 mm²

• Power Supply: Redundant, 24 VDC (+20 .. +33 V), typically 120 mA at 24 V

• Operating Temperature: 0 ... 50°C

• Status and Error Display: LED indicators for status and errors

• Power Supply Monitoring: Monitors power supply status

• Potential-Free Signaling Contact: Provides signaling for status and errors

• Mounting: Easy assembly on a DIN rail

Application

• Line Redundancy: Reinforces signal integrity and monitors all lines for activity and faults. Faults are indicated via an LED on the front panel, with diagnostic messages available on the 8-pole terminal strip.

• Combining Redundant Lines: Forwards the first correctly framed data from either line A or line B to connection M. In the case of simultaneous data arrival, one line is selected randomly. If an error is detected in one line, the control logic switches to the other available line.

• Splitting a Non-Redundant Line: Distributes correctly framed data arriving via connection M to lines A and B in parallel. Incorrectly framed data is not output to lines A and B.
