Selection Suggestions and Precautions
- Selection Suggestions
- Choose the EMERSON KJ4001X1-CK1 for DeltaV systems needing per-port fault isolation and high-density I/O connections.
- Match with DeltaV I/O cards (e.g., KJ3002X1-BA1) and confirm 2A current requirements for sensors/actuators.
- Prioritize for applications with wide temperature swings or dusty environments (IP20 protection).
- Precautions
- Use only DeltaV-compatible keys to avoid damaging the EMERSON KJ4001X1-CK1 or I/O cards during installation.
- Replace fuses with OEM-rated parts to maintain safety and compliance.
- Operate within -40°C to +70°C and avoid exposure to direct water jets (IP20 is not waterproof).
- Ensure proper torque on terminal screws (8-10 Nm) to prevent loose connections and signal degradation.
