Technical Specifications 24VDC power from carrier. 8 analog output channels. 4-20mA or 0-10V configurable. HART signal support. Galvanic isolation. Operating temperature:0°C ~ +60°C.
Functional Features Field wiring termination for modulating valve loops. HART pass-through for smart valve positioner. Output short-circuit protection. Channel fault detection support.
Application Scenarios Continuous process control loops in chemical, refinery, water treatment for control valve regulation.
Performance Parameters High linearity analog signal transmission, HART digital communication superimposed on analog output loop. Operating temperature:0~+60°C.
Structural Characteristics IOTA PCB board, field screw terminal block, connector to AO IOM module, signal conditioning and HART coupling circuit.
Working Principle Receive analog output signals from AO IOM module and route to field valve positioners. Transfer HART digital commands between DCS and smart valve positioner.
Installation Requirements Mount on Series-C carrier rack. Connect shielded cable to valve positioner. Configure output signal type in DCS engineering software.
Usage Notes Do not short output terminals. Calibrate valve zero and span after wiring.
