Information About 1756-DHRIO
The 1756-DHRIO is part of the Allen-Bradley ControlLogix 1756 communication module family, developed to bridge modern Logix platforms with older Allen-Bradley network infrastructures. This module supports two independent communication channels, each configurable for DH+ or RIO operation. In DH+ mode, it enables peer-to-peer communication between PLC-5, SLC 500, and ControlLogix controllers. In RIO mode, it allows the ControlLogix controller to act as a scanner or adapter for legacy remote I/O devices. It features high-speed data transfer, network diagnostics, and LED status indicators for simplified monitoring. Rack-mounted in a ControlLogix chassis, the 1756-DHRIO provides seamless integration of legacy systems into modern control architectures.
Key Features:
- Design: Dual-channel communication module for ControlLogix systems.
- Networks Supported: Data Highway Plus (DH+) and Remote I/O (RIO).
- Channels: Two independent ports configurable for DH+ or RIO.
- Compatibility: Interfaces ControlLogix controllers with PLC-5, SLC 500, and legacy I/O.
- Functionality: Supports peer-to-peer communication and RIO scanner/adapter roles.
- Diagnostics: LED indicators for channel status and network activity.
- Installation: Rack-mounted in 1756 ControlLogix chassis.
- Application Range: Suitable for system integration, legacy migration, and hybrid automation.
The 1756-DHRIO delivers the connectivity and flexibility required for integrating legacy networks with modern ControlLogix systems.
