Information About 1203-GU6
The 1203-GU6 is part of the Allen-Bradley 1203 family of communications modules, developed to provide seamless integration between DeviceNet networks and SCANport-based products. It features a 5-pin or 10-pin DeviceNet connector, an 8-pin mini-DIN SCANport connector, and an RS-232 port for configuration and diagnostics. Supporting peer I/O capabilities, it allows drives and controllers to broadcast or receive I/O data across the DeviceNet network. The unit operates on 24 VDC power with low consumption, while also drawing auxiliary power from SCANport. Compatible devices include Allen-Bradley 1305, 1336, 1394, 1397, and 1557 drives, as well as smart motor protection systems. The module offers configurable DIP switches for node address and baud rate, with factory defaults set at node 63 and 125 kbps. Built with a NEMA 1/IP30 enclosure, it withstands industrial environments with operating temperatures of 0–50 °C and humidity up to 95% non-condensing. Although discontinued, it remains a key component in legacy drive and control applications.
