Description
Description
The Emerson DeltaV KJ3001X1-BC1 is an 8-channel isolated discrete input module designed for the DeltaV Scalable Process System. This module provides reliable sensing for 24 VDC field signals in demanding industrial environments, including oil and gas, chemical processing, and power generation. Its isolated architecture is engineered to provide superior noise immunity and signal integrity, protecting sensitive control logic from field-side electrical disturbances.
Features
- 8 isolated discrete input channels for high-density signal monitoring.
- Designed for direct interface with 24 VDC field devices.
- Integrated hardware keying (B2 position) to prevent incorrect module-to-terminal block insertion.
- Supports hot-swapping in non-hazardous locations or under specific conditions in hazardous areas.
- Robust design compliant with ISA-S71.04-1985 Class G3 for protection against airborne contaminants.
Applications
This module is typically deployed in DeltaV I/O subsystems for monitoring status signals from field devices such as limit switches, proximity sensors, and auxiliary contacts. It is suitable for use in both standard industrial environments and hazardous area applications where Zone 2 compliance is required.

Installation Guidelines
- Ensure the system power is de-energized before installation or removal, unless specifically authorized for hot-swapping in your system configuration.
- Verify the terminal block keying (B2) matches the module before attempting to seat the card.
- Maintain proper grounding practices to ensure the effectiveness of the isolated input circuitry.
- Ensure adequate ventilation in the cabinet to maintain operating temperatures between 0 and 60 deg C.
- For hazardous area installations, ensure all field wiring complies with local electrical codes and the specific certification requirements (e.g., ATEX).
FAQ
Is this module hot-swappable?
Yes, the module supports hot-swapping when used with a compatible system power supply and provided that inductance limits are maintained. However, always ensure that field power is de-energized before maintenance in hazardous atmospheres to prevent ignition risks.
Does this module require field calibration?
No, the KJ3001X1-BC1 is a solid-state digital input module and does not require periodic field calibration. There are no user-serviceable parts inside the unit.
