Working Principle:
The KJ3006X1-BA1 receives pulse and analog signals from field devices through its terminal connections. Each channel employs a sigma-delta analog-to-digital converter that continuously samples the input signal. The module averages the digitized values over a configurable integration period, effectively filtering out process noise and power line frequency components. The averaged digital values are then transmitted to the DeltaV controller via the carrier backplane for processing and control algorithm execution.
Installation Requirements:
- Install the card into a compatible DeltaV I/O carrier slot
- Connect the terminal cable (Type 1) between the card and the terminal assembly
- Ensure the 37-pin connector is properly seated at the baseboard end
- Connect field wiring to the terminal assembly using compression-type or ring lug connections
- Verify wire gauge falls within the specified acceptance range (24 to 12 AWG)
Usage Precautions:
- Ensure terminal cable length does not exceed 30 meters
- Use appropriate wire gauge within the specified range for reliable connections
- Verify the terminal block keying matches the I/O card configuration before installation
- Do not disassemble the unit as it contains no user-serviceable parts
- Confirm proper grounding of the carrier and terminal assembly
