Material Composition
Housed in a rugged, shielded metal enclosure to provide complete EMI/RFI shielding and environmental protection.
Structural Characteristics
Features front-panel status LEDs for channel diagnostics and rear connectors for field wiring and backplane communication.
Working Principle
Accepts the analog signal from seismic sensors, conditions it through internal amplification and filtering, and digitizes it for processing by the 3400 system.
Installation Requirements
Install in an available slot in the 3400 rack. Ensure proper backplane connection and configure the module using the 3400 Configuration Software.
Usage Precautions
Verify that the connected sensors match the module’s input specifications. Perform regular system diagnostics to ensure proper operation.
