Product details

Overview

The HMISTU655S is a Schneider Harmony STU touch panel screen with a 3.5 inch QVGA TFT colour display at 320 x 240 pixels and 65536 colours, driven by an ARM926EJ-S processor. It runs on a 24 VDC external supply drawing 6.5 W, with IP65 sealing on the front panel and a NEMA 4X rating for indoor use, suiting it for washdown or dusty environments.

Integration

Connectivity includes one USB 2.0 type mini B, one USB 2.0 type A, and a COM1 serial link on female RJ45 supporting RS232C/RS485, with protocol support for Modbus TCP/IP and Uni-TE. The panel mounts via Ø 22 mm holes and carries CE, cULus, and Marine certifications, with immunity to microbreaks up to 10 ms.
