Overview
The Allen-Bradley 1203-GK5 is a DeviceNet communications module designed to provide gateway functionality between SCANport products and DeviceNet networks. This 1203-GK5 module mounts on standard 35 × 7.5 mm DIN rail systems and connects via SCANport cable to compatible drives. The module enables programmable logic controllers to communicate directly with sensors, drives, motor starters, and other smart devices across a DeviceNet industrial automation network.
Key Features
- DIN Rail Mounting: Mounts on a DIN rail system and connects to SCANport products with the use of a SCANport cable
- Configurable DIP Switches: DIP switches enable the user to configure the module before connecting it to the DeviceNet network
- Faulted Node Recovery: Faulted Node Recovery system, enabling one to change the node address of a device
- Customizable Fault Response: User fault response configuration allows the user to customize the adapter actions to communication errors, and LEDs aid in diagnosing network and SCANport health
- Multi-Rate DeviceNet: Baud rates for the 1203-GK5 are 125, 250, and 500 k BPS

- Baud Rates: 125, 250, and 500 kBPS
- Operating Temperature: 0 to 50 degrees Celsius
- Default Node Address: DeviceNet node address 63
- Default Data Rate: 125K
- Connector Types: 5-pin or 10-pin plug-in connector
- DIN Rail Requirement: 35 x 7.5 mm DIN rail
- Peripheral Support: Connections with SCANport products with up to 6 peripherals
Typical Applications
The DeviceNet network is widely known in the industry as an open, global industry-standard communication network that offers an interface through a single cable. This interface can be developed through a programmable controller directly to smart devices such as sensors, pushbuttons, motor starters, and drives. The 1203-GK5 module is ideal for retrofit and expansion applications in manufacturing, packaging, and process automation environments where legacy SCANport-based drives require modern DeviceNet connectivity.
