4.3″ PLC HMI Controller – 12 DI / 12 DO Transistor (High-Speed) + Optional I/O

This integrated PLC HMI controller combines control logic, high-speed digital outputs, and operator interface into a single compact unit, making it ideal for modern industrial automation and machine control systems.

The 4.3″ colour touchscreen provides real-time monitoring, control, and parameter adjustment without the need for a separate HMI panel, reducing system complexity and panel space requirements.

With 12 digital inputs (DI) and 12 transistor outputs (DO), this unit is specifically suited to high-speed switching applications where fast response and frequent switching are required. Transistor outputs offer significantly faster switching performance compared to relay-based models, making them ideal for dynamic control tasks.

The controller supports a wide range of analogue input configurations, allowing direct connection of:

• Temperature sensors (PT100, thermocouples, NTC)
• Voltage signals (0–10V)
• Current signals (0–20mA)

Optional analogue outputs provide direct control of external devices such as:

• Variable speed drives (VSDs)
• Control valves
• Process actuators

This makes the unit suitable for both monitoring and closed-loop control applications.
