Emerson KJ3221X1-BK1 12P4704X042 Analog Output Card
The Emerson KJ3221X1-BK1 12P4704X042 is an 8-channel Analog Output (AO) card designed for use with the Emerson DeltaV industrial automation system. It converts digital signals from the DeltaV controller into analog current signals (4-20mA) that can be used to control various industrial equipment like valves, motors, and drives. This allows for precise control of process variables like pressure, flow, and temperature. Features 8 independent analog output channels Supports HART (Highway Addressable Remote Transducer) protocol for advanced diagnostics and communication with intelligent field devices Configurable current range High accuracy and resolution for precise control Isolated outputs to minimize electrical noise and improve signal integrity Compact design for easy installation in control cabinets Technical Specifications Number of Channels: 8 Output Type: Analog Current (4-20mA) Communication Protocol: HART Accuracy: Typically 0.1% of full scale Resolution:
