Technical Specifications General Manufacturer: Emerson Automation Solutions Model Number: KJ3221X1-EA1 Product Type: Redundant Analog Output Terminal Block System Compatibility: Emerson DeltaV DCS I/O infrastructure Primary Function: Provides redundant field termination points for DeltaV analog output channels (e.g., paired with analog output I/O cards). Electrical Input Power / Field Power Rating: ~30 V DC @ 0.2 A typical terminal block power rating (used to power LED indicators and internal circuitry) Signal Type: Designed for analog output signal loops (4–20 mA with HART protocol) when used with appropriate I/O cards or modules Environmental Operating Temperature: −40 °C to +70 °C Relative Humidity: 5 % to 95 % non-condensing Shock & Vibration: Meets industrial shock & vibration standards for DCS I/O components Shock: 10 g half-sine wave @ 11 ms Vibration: ~1 mm peak-to-peak; ~0.7 g (broadband industrial test profile) Airborne Contaminants: ISA-S71.04 Class G3 (These environmental ratings align with typical DeltaV I/O and terminal block specifications.) Certifications & Safety Certified for use in hazardous atmospheres under ATEX, IECEx, and other industrial safety standards (specific approvals vary by configuration and region) Features Redundant design supports increased system reliability for critical analog loops Industrial ruggedness for harsh plant environments Designed for DeltaV integration with matched I/O cards and carriers Secure screw-type terminal clamping for field wiring termination
