The Schneider Electric HMISCU6B5 is a 3.5-inch Harmony SCU color touch controller panel combining a 320 x 240 QVGA display with 8 digital inputs, 8 digital outputs, 4 analogue inputs, and 2 analogue outputs. It runs on 24 V DC, uses an ARM926EJ-S processor, and connects via RS232/RS485, Ethernet TCP/IP, CANopen, and USB for compact machine control.
The HMISCU6B5 packs a full discrete and analogue I/O set, 8 DI, 8 DO, 4 AI, 2 AO, behind a 3.5-inch display, so it functions as a combined HMI-plus-controller on compact machines rather than a display-only panel. Choose the larger HMISCU8A5 (5.7-inch, 16 DI/10 DO) when the application needs more I/O points or a bigger screen on the same SCU architecture. CANopen master and Modbus TCP/IP support let it supervise simple distributed I/O without a separate PLC.
