Working Principle: The module receives raw signals from seismic sensors or proximity probes and transmits these signals through external terminals to the 3500/42M main module for processing. The main module conditions, filters, and analyzes the signals, comparing measured values against user-programmable alarm setpoints to generate alarms when exceeded. The module simultaneously provides buffered sensor outputs for use by other equipment.
Installation Requirements:
- Install in the rear slot corresponding to the 3500/42M main module
- External terminal blocks connect to the module via dedicated cables
- Sensor cables must use shielded cables with proper grounding
- Ensure terminal blocks are securely installed with reliable connections
- Maintain appropriate spacing from high-voltage power cables
Use Precautions:
- This module must be used with the 3500/42M main module
- External terminal blocks must be ordered separately, selecting correct model for sensor type
- Inspect external connection cables regularly for tightness
- In vibration environments, ensure cables are securely fastened to prevent loosening
- Module replacement does not require disconnecting sensor wiring
