Turck CDN-IOM-22-0012 Bus Stop Junction Box DeviceNet Distributed IO

The Turck CDN-IOM-22-0012 Bus Stop Junction Box is a compact DeviceNet distributed I/O module that collects two digital inputs and drives two digital outputs, enabling decentralized machine control with a central PLC. Designed for machine-mounted use in conveyors, packaging lines, material handling, assembly cells, and broader factory automation, it’s built to minimize field wiring with a compact Bus Stop design and to interface reliably on a DeviceNet network. Electrical specs include 11–25 VDC input at 80 mA per input, with input compatibility for 3-wire PNP, NPN, or dry contact devices; output voltage 18–26 VDC (auxiliary supply required) with two solid-state relay outputs rated at 1 A per output (2 A max per station), and a DeviceNet Bus Interface for network connectivity. The module is IP67 rated for harsh environments and is intended for machine-mounted installations to support distributed digital I/O control and quick replacement or retrofit of DeviceNet networks; common replacements include Turck FDNP-IOM22-0001, TBEN-S2-2DXP, and BLCDN-4M12LT-4XSG-P.
