Technical Specifications 24VDC control power supply; multi-channel discrete digital inputs and relay trip outputs; hardware-based fast trip circuit; on-board non-volatile memory for fault event storage. Operating temperature range: -40℃ ~ +85℃.
Functional Features Multi-condition unit fault detection; hardwired emergency trip relay output; audible and visual alarm signal driving; fault event recording and status latch; channel self-test function for circuit health verification.
Application Scenarios Gas turbine, gas engine and large genset safety control cabinets, used as independent protection subsystem.
Performance Parameters Ultra-fast trip response latency; high contact reliability for safety relay; stable logic operation under strong electromagnetic interference environment.
Structural Characteristics Rack pluggable printed circuit board; built-in metal shielding layer; dedicated onboard terminals for trip signal wiring.
Working Principle The board continuously monitors digital status signals from field safety switches and sensors.
Usage Notes Conduct complete trip logic simulation test before unit commissioning; inspect relay contact condition during regular overhaul; cut off power before removing the board.
