OP-920 Series Human Machine Interface
OP-920 Series is the Human Machine Interface, which connects PLC directly, extra power supply is not required for OP-920, 2.6" STN single color LCD, gray color LED background light illuminatiin,with 128KB memory, white keyborad panel.Therefore the op
OP-920 Series is the Human Machine Interface, which connects PLC directly, extra power supply is not required for OP-920, 2.6" STN single color LCD, gray color LED background light illuminatiin,with 128KB memory, white keyborad panel.Therefore the opreation of machines and devices is more convenient and easier. 


1. The OP920 are to be mounted on the face of a control or operations panel, and connected to the programming port (CPU port) of a PLC.

2.  Various devices can be monitored and PLC data changed through the screens in the OP920.

3. Using PLC programming software, HC Series PLC user programming can be uploaded, downloaded and monitored via the OP920.

4. The OP920 is driven by 5V DC power supply (from the PLC through a communication cable).

5. The OP920 can be connected to the TX/LX Series PLC, PLC manufactured by another company and micro computer board.

For further details concerning applicable PLCs and connections to the PLC, refer to the OP920 Series Hardware Manual (Connection Diagram) offered as a separate volume.
