07 KP 90 ABB Communication Module via RCOM protocol

Features

• Versatile Communication: The RCOM protocol supports data exchange between different ABB control systems and within Advant Controller 31 systems. It allows for long-distance communication via various media, such as leased lines, telephone lines, and existing cable paths.
• Adaptable Transmission: Transmission path adaptation can be achieved by selecting different modems (e.g., VF or current loop modems, telephone modems, multidrop modems).
• Network Structure: An RCOM network comprises a master and multiple slaves. It supports master-to-slave data transmission, master reading data from slaves, and event-driven transmission where a slave can store and transfer process events with timestamps to the master upon request.

Technical Data

• Number of Serial Interfaces: 2
• Number of Parallel Interfaces: 1 networking interface for connecting to the Advant Controller 31 basic unit
• Operating and Error Displays: 6 LEDs: RUN, ERR, Supply, RxD, TxD, BLK
• Conductor Cross Section for Removable Terminal Blocks: max. 2.5 mm²

Power Supply for 07 KP 90 R303

• Rated Supply Voltage: 24 V DC
