ABB 200-CI232 Communication Interface

This communication interface connects ABB AC500 PLCs to serial field devices. It provides a standard RS-232 port for programming and data exchange. Therefore, this component enables communication with barcode readers, drives, and operator panels.

Physical Dimensions and Weight Specifications

The ABB 200-CI232 features a compact housing for DIN rail mounting. Its width measures 45 mm for standard industrial enclosures. The total depth reaches 100 mm including the connector block. Consequently, technicians can install this unit in tight cabinet spaces.

Interface Types and Connection Layout

The ABB 200-CI232 provides a 9-pin D-sub connector for the RS-232 cable. A 10-pin backplane connector links directly to the AC500 bus. The front panel carries two LED indicators for transmit and receive activity. Hence, operators can monitor communication status at a quick glance.

Component Count and Communication Protocol

This communication interface contains one main board with a UART controller. The board holds 8 KB of FIFO buffer memory for data queuing. You will also find ESD protection circuits on the RS-232 port. An onboard oscillator generates the baud rate clock signal.

Energy Storage and Power Consumption

The ABB 200-CI232 draws 60 mA from the 5V backplane supply. It requires no external power supply for communication circuits. A small capacitor filters noise on the RS-232 power lines. This storage ensures clean signal transmission in industrial environments.

Communication Performance and Diagnostics

The interface handles full-duplex communication at all supported baud rates. It includes built-in loopback testing for diagnostic verification. Users can configure protocol parameters via the PLC programming software. This flexibility supports a wide range of serial devices.
