Overview

The KJ3101X1‑BB1 is a Safe Discrete Input Module for Emerson’s DeltaV SIS safety system. It captures discrete (on/off) signals from field devices such as pushbuttons, limit switches, and emergency stop switches, ensuring that critical shutdown or interlock signals are reliably transmitted to the SIS logic solver.

Engineered for high-integrity safety applications, the module is TÜV‑certified for SIL 3 and designed for intrinsically safe (IS) installations, making it suitable for oil & gas, chemical, and power generation industries.

Technical Specifications

Typical Applications

• Emergency Shutdown Systems (ESD): Captures signals from emergency stop switches and shutdown pushbuttons.

• Fire & Gas Systems: Interfaces with flame detectors, gas sensors, and alarm contacts.

• Process Safety Interlocks: Monitors limit switches and interlocks in chemical and petrochemical plants.

• Oil & Gas Facilities: Provides safe input monitoring for drilling rigs, refineries, and pipelines.

• Power Generation: Ensures reliable input capture for turbine and boiler safety systems.

Example:
In a refinery safety system, the KJ3101X1‑BB1 collects emergency stop and limit switch signals, ensuring the SIS can trigger a safe plant shutdown if hazardous conditions are detected.
