The HITECH PWS6600S-S is a 5.7-inch monochrome STN LCD HMI touch panel with 320×240 resolution, 16 shades of blue, and analog resistive touch screen. Powered by a 32-bit RISC CPU with 4MB Flash ROM, 512KB RAM, and battery-backed RTC, it provides dual communication ports (COM1: RS-232/485, COM2: RS-232/422/485) for PLC connectivity. The IP65/NEMA 4 front panel and 24V DC power input make it suitable for industrial environments. Configured via ADP6 software, it supports multiple PLC protocols. Applications include machine operator interfaces, production line monitoring, process visualization, and equipment control panels. Note: This model is End of Life (EOL 2020-11-01); the successor is the Beijer X2 series.
**Q: What is the replacement for the PWS6600S-S?**
A: Beijer Electronics (which acquired HITECH) recommends the X2 series HMI panels as the modern replacement with color TFT displays, Ethernet, and USB support.
**Q: Does the PWS6600S-S support Ethernet communication?**
A: No, the standard "S" version has serial communication only (RS-232/485). Ethernet is available on the PWS6600S-N variant.
**Q: How is the HMI programmed?**
A: The panel is configured using ADP6 software from HITECH/Beijer, which supports ladder logic-style screen design and multi-vendor PLC protocol drivers.
