Maple Systems has introduced three new models including a 7 in. (HMI5070P), 12.1 in. (HMI5121P) and 15 in. (HMI5150P) TFT touchscreen displays. The touchscreens are housed in a sleek aluminum enclosure that is compact and resistant to corrosion. The microprocessors are specifically designed for efficient graphic animation and heavy data processing. The HMIs connect to a long list of PLCs, drives and motion controllers through two serial ports, a USB port, a CAN bus port and an Ethernet port (including support for BACnet and importing tag data for Rockwell Automation and Siemens PLCs).
