Working Principle
The PO400ZG receives analog signals from field devices, converts them into digital signals, and transmits them to the controller via the node bus. Simultaneously, it receives digital commands from the controller and converts them into 4-20mA analog signals to drive field actuators.
Installation Requirements
- Must be correctly connected to the A/B dual channels of the redundant node bus.
- Analog signal wires must use shielded cables and be routed away from power lines.
- Ensure the module power supply voltage is stable within the 12-24 VDC range.
Usage Precautions
- Strictly prohibited to short-circuit the voltage output terminals.
- Ensure input/output ranges match the actual field devices during configuration.
- Regularly check the module’s communication status and indicator lights.
