Working Principle: Convert internal bus analogue control signals to standard field analogue signals, provide wiring interface, detect open circuit and short-circuit faults of field cables, and feed fault information back to the main controller.
Material Composition: FR4 printed circuit board, flame-retardant ABS plastic housing, copper alloy terminal connectors, industrial-grade surface-mount electronic components.
Structural Characteristics: Plug-in card structure, matched system rack slot installation; upper terminal wiring area, lower backplane connector; modular split design convenient for maintenance without rewiring.
Application Scenarios: Oil & gas process control, petrochemical SIS safety system, power plant boiler control, refining unit modulating valve control.
Installation Requirements: Install in standard control cabinet rack, vertical mounting; maintain 20mm ventilation gap between adjacent modules; wiring conductor maximum cross-section 1.31mm² (16AWG), wire stripping length 6mm.
Usage Notes: Strictly avoid signal wiring and power cable parallel laying; do not hot plug under load; regularly check terminal fastening torque; conformal coated version applicable for high-corrosion environments.
