1.3 Wiring
Before connecting any wires, ensure that the power supply is disconnected. Refer to the wiring diagram below for proper connections. This device requires a DC 24V input.
Figure 1: Rear panel of the QM3G-43FH HMI PLC. This image displays the various input/output terminals, communication ports (RS232, RS485, USB), and the DC 24V power input. The model number QM3G-43FH and version mView1.38 are visible on the label.
- Power Input (DC 24V): Connect the 24V DC power supply to the designated terminals. Ensure correct polarity. The OCR indicates 'INPUT:DC24V'.
- Digital Inputs (X00-X13): Connect your digital input signals to the 'X' terminals on the left side.
- Digital Outputs (Y00-Y13): Connect your digital output devices to the 'Y' terminals on the right side.
- Analog Inputs (AD0-AD3): Connect analog sensors or signals to the 'AD' terminals.
- Analog Outputs (DA0-DA1): Connect analog output devices to the 'DA' terminals.
- Communication Ports (COM1/COM2, RS232, RS485): Use the DB9 connector for RS232/RS485 communication. The device supports both RS232 and RS485 protocols.
- USB Host: For connecting USB devices such as flash drives for program transfer or data logging.
- Ethernet Port (LAN): Connect to a network for remote monitoring or programming (if applicable to the specific model variant).
- Grounding (FG): Ensure proper grounding of the unit to prevent electrical interference and ensure safety.
Caution: To prevent electric shock, do not remove the cover. No user serviceable parts are inside. Refer servicing to qualified personnel.
