Overview
The Allen-Bradley 1203-GK5 is a DeviceNet communications adapter designed to provide seamless integration between SCANport products and DeviceNet networks. As a gateway module, it enables programmable controllers and smart industrial devices to communicate over DeviceNet, an open, global industry-standard network that uses a single cable for multi-device connectivity. This used module has been tested for operational integrity and mounts directly to DIN rail for space-efficient installation.
Key Features
- SCANport Integration: Connects up to 6 SCANport peripherals on a single gateway
- DIP Switch Configuration: Easy setup with configurable node address (0–63), data rate (125K, 250K, 500K baud), and datalink settings
- Faulted Node Recovery: Automatic recovery system and dynamic node address remapping capability
- Diagnostic LEDs: Bi-color LED indicators for real-time network and SCANport health monitoring
- Plug-In Connectors: Compatible with 5-pin and 10-pin industrial connectors for flexible deployment
- PCCC Message Support: Firmware v2.001+ enables native PLC message pass-through for legacy system compatibility

Typical Applications
The 1203-GK5 is widely deployed in:
- Industrial drive control systems using 1305, 1336 Plus, and 1336 PlusII drives
- DeviceNet networks integrating multiple sensors, pushbuttons, motor starters, and actuators
- Legacy PLC systems requiring PCCC message compatibility for brownfield upgrades
- Motion control systems that require deterministic, time-critical communication
- Manufacturing and process automation where multi-drop networks reduce wiring complexity
