Functional Overview

Redundant Wiring: Two independent terminal blocks operate in parallel. Any single-point failure will not cause system shutdown, meeting SIL 2–3 safety requirements.
Multi-Signal Compatibility: Directly accepts common industrial signals such as 4–20 mA, 0–10 V, and 24 VDC, simplifying integration with field instruments and sensors.
Modular Design: Supports DIN-rail mounting for fast installation, maintenance, and expansion on site.
High Immunity to Interference: Equipped with surge protection and overload protection, suitable for environments with high electromagnetic noise.

Typical Application Scenarios

Power Plant Safety Systems: Redundant monitoring of critical valves, rotors, burners, etc., preventing shutdowns or safety incidents caused by single-point failures.
Chemical / Oil & Gas Processes: Collects pressure, temperature, flow, and other signals under high-temperature and high-pressure conditions to ensure process safety.
Pharmaceutical / Food & Beverage: Supports GMP-compliant process control and data recording, providing reliable signal transmission.

In summary, the EMERSON KJ2201X1-JA1 is a redundant terminal block designed specifically for industrial safety instrumented systems. With high reliability, a wide operating temperature range, and compatibility with various signal types, it is widely used in power, chemical, oil & gas, and other critical process industries for safety control.
