Technical Specifications General Manufacturer: Emerson Automation Solutions Model Number: KJ3222X1-EA1 Product Type: Redundant Analog Input Terminal Block System Compatibility: Emerson DeltaV Distributed Control System (DCS) Application: Provides redundant wiring termination for analog input loops to DeltaV analog input I/O cards. Electrical Input Power Rating: 30 V DC @ 200 mA typical (Terminal block itself does not process signals – power is used for internal circuitry such as indicators and redundant interface.) Signal Types Supported: Analog input signals routed through to redundant input cards (field-to-I/O connectivity). Environmental Operating Temperature: −40 °C to +70 °C Shock Resistance: 10 g half-sine, 11 ms Vibration Resistance: 1 mm peak-to-peak (2–13.2 Hz) 0.7 g (13.2–150 Hz) Airborne Contaminants: ISA-S71.04-1985 Class G3 Relative Humidity: 5 % to 95 % non-condensing Certifications & Safety Approvals Certified for use in hazardous areas under ATEX/IECEx and related standards: II 3G Ex ec nC IIC Gc FM18ATEX0076U / IECEx FMG 18.0030U / FM21UKEX0199U Class I Division 2 GP A,B,C,D Class I Zone 2 AEx/Ex ec nC IIC Tc Gc (specific approvals depend on region and configuration) Key Features Redundant design provides dual termination paths for analog input signals, increasing system reliability in critical applications. Industrial-grade construction to withstand harsh process environments. Seamless DeltaV integration with redundant analog I/O cards and carriers. Supports installation in hazardous locations with appropriate safety approvals.
