Physical Characteristics and Installation

This DeviceNet PC board weighs approximately 0.45 kg for secure rack mounting. Its dimensions measure 220 mm x 180 mm x 25 mm for CNC controller cabinets. First, align the A16B-2203-0190/06B with the backplane guides. Then, press firmly until the board seats completely. Finally, secure the board using the top and bottom retaining screws. A conformal coating protects the PCB from moisture and dust.

Communication Specifications

The A16B-2203-0190/06B supports three selectable baud rates for network flexibility. You can choose 125 kbps, 250 kbps, or 500 kbps for your application. The maximum cable length reaches 500 meters at 125 kbps. At 500 kbps, the maximum length reduces to 100 meters. This board supports up to 64 DeviceNet nodes on a single network. 500V DC isolation protects the CNC backplane from network electrical noise.

Power Requirements and Compatibility

This board draws 200 mA from the 5V DC backplane for logic circuits. The DeviceNet transceiver requires an external 24V DC supply drawing 100 mA. The A16B-2203-0190/06B communicates with DeviceNet slaves such as VFDs, I/O blocks, and sensors. Use this board to integrate GE Fanuc CNCs into Rockwell ControlLogix or CompactLogix systems.
