Product Overview

The ALLEN-BRADLEY 1336-GM5 is a DeviceNet communication board designed to provide a direct electronic interface between a DeviceNet network and compatible Allen-Bradley SCANport products, primarily the 1336 PLUS series adjustable frequency drives -5-8. Unlike its counterpart, the 1203-GK5 external module, the ALLEN-BRADLEY 1336-GM5 is an embedded board that mounts directly inside the drive enclosure, connecting to the host device’s internal SCANport connector -8-12. This integration eliminates the need for an external mounting rail and interconnecting cables, reducing panel space requirements and installation complexity.

As a DeviceNet adapter, the ALLEN-BRADLEY 1336-GM5 enables seamless integration of the drive into a DeviceNet network, allowing for remote monitoring, control, and configuration. The board supports baud rates of 125, 250, and 500 kbps, with 125 kbps set as the factory-default data rate -1-11. It accepts a supply voltage of 12-25 VDC directly from the DeviceNet network, consuming only 40 mA of current -1-8. The ALLEN-BRADLEY 1336-GM5 is equipped with DIP switches for configuring the node address and communication parameters, as well as dual-color LEDs for diagnostic status indication of both DeviceNet network and SCANport connection health -7-8.

Main Features and Advantages

Embedded design for simplified installation:
The ALLEN-BRADLEY 1336-GM5 is designed as a board that mounts directly inside compatible SCANport products, connecting via an internal 14-pin connector -8-12. This embedded form factor eliminates the need for external mounting, separate DIN rail space, and interconnecting cables required by modular adapters like the 1203-GK5. The board includes four Phillips mounting screws and stand-off nylon headers for secure installation -6.

DIP switch configuration for rapid deployment:
The ALLEN-BRADLEY 1336-GM5 features two banks of DIP switches (SW1 and SW2) for easy configuration without specialized software -11. SW2 switches 1-6 set the node address (default 63), while SW2 switches 7-8 configure the DeviceNet data rate (factory default 125 kbps) -11. SW1 switches provide advanced configuration options including Datalink A-D enable/disable, Zero Data/Hold Last State selection, and Fault on Communication Loss behavior -11.

Comprehensive diagnostic LED indicators:
The ALLEN-BRADLEY 1336-GM5 is equipped with two dual-color LEDs providing clear visual status indication -8. The DeviceNet network LED (near the DeviceNet connector) indicates network status, including powered but offline (off), online with no established connection (flashing green), online and connected (steady green), I/O connection timeout (flashing red), and bus-off or address conflict (steady red) -8. The SCANport status LED indicates the health of the connection to the host drive, covering states from no power (off) to normal communication (steady green) and various fault conditions (flashing red, steady red, or steady orange) -8.

Robust industrial specifications:
The ALLEN-BRADLEY 1336-GM5 is built to withstand demanding industrial environments. It offers 8 kV ESD contact susceptibility, operates over a temperature range of 0°C to 50°C, and can be stored from -40°C to 85°C with up to 95% non-condensing humidity -1.
