Material Composition & Structural Characteristics:
- Enclosure: Compact, flame-retardant industrial plastic housing.
- Internal Components: High-quality precision resistors and operational amplifiers.
- Connectors: Standardized PCB pin headers or industrial plug-in terminals.
Working Principle:
The board utilizes a precision resistor divider network to step down the high-voltage input to a safe, measurable level. The conditioned signal is then processed and isolated before being output as a standardized analog signal to the main controller for system regulation.
Installation Requirements:
- Must be securely mounted on the designated backplane or DIN rail within the control cabinet.
- High-voltage input wiring must be routed separately from low-voltage signal cables.
- Ensure all grounding connections are properly tightened.
Usage Precautions:
- Never exceed the maximum rated input voltage to prevent permanent damage.
- Always de-energize the system before installing or replacing the board.
- Handle with ESD precautions to protect sensitive internal components.
