Product Description

The 1756-DHRIOXT module, a key component of the ControlLogix DHRIO series, facilitates high-speed communication between legacy devices and modern automation systems. Equipped with dual-channel support for DH+ and Remote I/O (RIO) protocols, this module provides two independent DH+ communication interfaces, each capable of connecting up to 32 nodes on a DH+ network. Designed for industrial applications like manufacturing, utilities, and process control, it operates at 24V DC with a temperature tolerance of 0°C to 60°C. The module integrates seamlessly with ControlLogix backplanes, supporting cascading connections across multiple chassis. Its standout features include protocol conversion flexibility and backward compatibility with Allen-Bradley legacy systems. However, its dependency on aging DH+ technology limits bandwidth compared to modern Ethernet-based solutions. The compact form factor ensures efficient rack space utilization while maintaining robust performance in demanding environments.
