Schneider Electric HMISCU6A5 Harmony SCU 3.5-inch Color Touch Controller Panel 16 DI 10 DO HMI Operator Panel

The Schneider Electric HMISCU6A5 is a Harmony SCU small touch HMI controller combining a 3.5-inch QVGA colour touchscreen with 16 digital inputs and 10 digital outputs on a single 24 V DC-powered unit. Its ARM926EJ-S processor runs CANopen, Modbus, and Modbus TCP/IP, letting it act as both the operator display and the machine's I/O controller.

Selection Notes

Pick the HMISCU6A5 over its 5.7-inch sibling when the machine needs 16 digital inputs and 10 digital outputs on a compact 3.5-inch panel rather than the larger model's mixed analogue/digital I/O set — both run the same ARM926EJ-S controller and CANopen/Modbus stack, so the choice is driven by I/O count and panel footprint, not processing capability. Its single RS-232/RS-485 serial port plus CANopen master bus covers simple machine networks without adding a separate PLC.
