ABB CMA 33 Communication Interface Module

Description

No direct technical specifications are available for the ABB CMA 33 Communication Interface Module, but reference can be made to comparable ABB communication interface modules. For example, the 200-CIE/200-CICN communication module features an RS-485 interface for serial communication, supporting baud rates from 9.6 kbps to 115.2 kbps. Designed exclusively for the ABB AC 500 PLC series, it draws power via the backplane bus, operates in temperatures from 0 degrees Celsius to 60 degrees Celsius, has a storage temperature range of -40 degrees Celsius to 85 degrees Celsius, carries an IP20 protection rating, and has a compact form factor for installation in expansion slots, ideal for industrial automation applications like connecting PLCs to HMIs, sensors, and variable frequency drives. The CI853-1 communication interface module supports multiple protocols including Modbus RTU and TCP/IP, enables high-speed, reliable data transfer via serial or Ethernet interfaces, supports hot-swapping, and is compatible with ABB’s COMLI protocol for controller-to-controller communication, with fiber converters extending cable lengths to several kilometers. The CI930F communication interface module is a compact, universal solution that facilitates secure, reliable communication between ABB products and third-party devices, with easy installation and configuration for seamless system integration.
