ABB Bailey INSIM01 Serial Module

This serial interface module connects RS-232 and RS-485 devices to ABB Bailey systems. You will find the ABB Bailey INSIM01 Serial Interface Module managing data exchange with modems, printers, and terminals. Its dual-port design supports simultaneous communication with two independent serial devices.

Technical Specifications

This module contains two fully isolated serial communication channels. You can also locate ten configuration DIP switches for protocol adjustment. The ABB Bailey INSIM01 Serial Interface Module stores no battery energy for configuration retention. Instead, it uses non-volatile EEPROM for all communication settings. Therefore, this module never requires any routine battery replacement.

Communication Details

The ABB Bailey INSIM01 Serial Interface Module draws its operating power from the INFI 90 bus backplane. You can configure each port independently for RS-232 or RS-485 operation. The module buffers incoming characters before forwarding complete messages to the controller. Moreover, the ten DIP switches set baud rate, parity, and protocol without software tools. This design enables fast field commissioning using only a small screwdriver.

Mechanical Integration and Mounting

You must insert the ABB Bailey INSIM01 Serial Interface Module carefully into any standard INFI 90 slot. After full insertion, secure the module using the top and bottom metal retaining clips. The module measures exactly 25.5 centimeters in length and 3.2 centimeters in width. Its total weight reaches approximately 0.44 kilograms for straightforward handling. Furthermore, the four status LEDs indicate transmit and receive activity on both ports.

Environmental and Storage Guidelines

You should store this ABB Bailey INSIM01 Serial Interface Module in an anti-static bag away from moisture. The module operates reliably between 0°C and +60°C ambient temperature. Likewise, keep the unit away from conductive dust or strong electromagnetic fields. Because the module uses solid-state components only, it requires zero regular maintenance over its service life.
