Technical Specifications 24VDC power supply; multi-channel isolated digital input; input surge suppression circuit. Operating temperature: -40℃ ~ +85℃.
Functional Features Field switch status acquisition; input signal isolation; channel fault diagnosis; noise suppression for dry contact signal.
Application Scenarios Turbine, gas engine and genset control cabinets for interlock and status monitoring.
Performance Parameters Fast signal response, high input isolation voltage, reliable signal acquisition in harsh industrial environment.
Structural Characteristics Rack pluggable PCB, onboard terminal blocks for field signal connection.
Working Principle Field dry contact or digital status signals are sent to this board. After isolation and filtering processing, the digital status data is transmitted to the main processor for logic judgment.
Installation Requirements Separate field status wiring and high-power cables to reduce interference.
Usage Notes Check input channel status during unit commissioning; avoid overvoltage applied to input terminals.
