Allen Bradley 1797-BIC Flex Ex I/O Bus Isolator Module

Product Introduction

The Allen Bradley 1797-BIC Flex EX I/O Bus Isolator Module is a specialized module designed to provide electrical isolation and protection for FLEX EX I/O networks. It ensures reliable communication between distributed I/O devices while safeguarding the system from voltage spikes, ground loops, and other electrical disturbances.

This module operates as a bus isolator, maintaining signal integrity across the network and preventing faults in one segment from affecting the rest of the system. It supports 18–32 VDC power input with a current rating of 150 mA and power consumption of 2.5 W, making it suitable for efficient and stable operation in industrial environments.

With a compact form factor, open-style design, and DIN rail mounting capability, the 1797-BIC can be easily integrated into control panels. It is widely applied in distributed control systems, process automation, and industrial networks requiring robust bus isolation and reliable communication.
