HE7 Touch Screen Programming Controller
  1.  All-in-One HMI + Programming Controller PLC with 7-inch Touch Screen and Ethernet IO

The WoMaster HE7 Programming Controller is a compact and powerful all-in-one solution that integrates a 7-inch touch screen HMI with a versatile PLC controller. Designed for industrial automation applications, it supports STEP 7-MicroWIN SMART programming and all S7-200 SMART instructions, offering a familiar development environment for engineers. With its user-friendly interface and seamless integration, the HE7 simplifies system design and reduces wiring and communication complexity. Equipped with Ethernet and RS485 ports, the HE7 supports multiple protocols including S7 TCP, MODBUS TCP/RTU, GET/PUT, and PPI, allowing for flexible connectivity with SCADA systems and other devices. Its opto-isolated I/O, high-speed pulse output, and real-time clock functions ensure reliable and precise control, even in harsh industrial environments.
