ABB CM672 PROFIBUS DP Communication Module

Description

The ABB CM672 PROFIBUS DP Communication Module is an industrial communication component designed for seamless data exchange in automated systems, with performance aligned with standard PROFIBUS DP specifications. It features a communication rate range of 9.6 kbit/s to 12 Mbit/s, supporting automatic baud rate adaptation to let users select optimal speeds based on on-site conditions; at 9.6 kbit/s, it achieves a maximum transmission distance of 1000 meters with shielded cable, meeting both short-range high-speed and long-range industrial networking needs. Equipped with 1 PROFIBUS DP standard RS485 physical layer interface with a Sub-D 9-pin male connector, it uses shielded twisted pair differential transmission for strong anti-interference capability, and includes short-circuit protection, overvoltage protection, and resistance to ±15kV electrostatic discharge to prevent damage from industrial electromagnetic interference or wiring errors. The module has compact dimensions of 40mm (width) × 125mm (height) × 120mm (depth), weighs approximately 0.35 kg, and features a flame-retardant ABS housing. It mounts directly to standard 35mm DIN rails, suitable for dense cabinet layouts, and supports use cases like workshop equipment interconnection, cross-plant communication, and data transfer between PLCs, drives, and remote I/O devices.
