Allen-Bradley 1203-CN1

The Allen-Bradley 1203-CN1 ControlNet communications module is designed as a vital link between ControlNet networks and SCANport devices, delivering reliable and deterministic I/O control. This module supports redundant media and unscheduled messaging, making it a versatile choice for various applications. Operating on a 24V DC power supply with a current draw of 250 milliamps, it features a standard 8-pin circular mini-DIN SCANport connector for straightforward setup, though it accommodates one SCANport device at a time. The 1203-CN1 includes an RS-232 serial port and a network access port, along with bi-color LEDs that provide real-time status updates. Designed for easy installation, it mounts securely on a DIN Rail and requires users to set a node address using a blunt instrument before initial power-up to avoid potential damage, ensuring both performance and longevity in demanding environments.
