LIEBHERR 926320114 RELAY CARD 0002 555 57 00 021 0
LIEBHERR 926320114 is rack plug-in marine deck crane relay output printed circuit board, designed for Liebherr marine deck crane hydraulic automation control system, widely fitted onboard cargo vessels, heavy-lift ships and offshore platforms for emergency circuit switching, interlock signal output and machinery fault relay control. This marine relay card receives control commands from the main crane CPU board, drives potential-free relay contacts to activate emergency stop, limit switch interlock and alarm circuits for deck crane safety protection. The marine relay card integrates multi-channel relay switching circuit, surge protection, watchdog monitoring and contact status feedback, supports fault log storage and emergency cut-off logic for overload and collision protection applications. Its relay switching & hardware diagnostics function continuously monitors 24V DC power supply, field control wiring and backplane bus integrity, detects coil failure, contact burnout and signal loss, transmits relay card fault alerts and crane safety status to vessel AMS alarm console. The relay switching & hardware diagnostics ensures reliable safety circuit switching for Liebherr marine deck crane hydraulic automation control system. It enables reliable marine 926320114 relay card operation under heavy vessel vibration and salt mist marine environments.

This Liebherr 926320114 relay card delivers stable marine deck crane relay output printed circuit board performance installed inside vessel deck crane control cabinet. The relay switching & hardware diagnostics adopts marine-grade PCB substrate with EMC shielding against electromagnetic interference and mechanical shock. Marine crane technicians rely on marine 926320114 relay card operation to test relay switching action, verify contact condition and inspect card status during routine maintenance. It adopts rack edge connector plug-in design for straightforward spare replacement and minimal marine deck crane automation system downtime. Internal circuit boards use conformal coating to protect electronic components against salt mist, condensation and temperature fluctuation. It works cooperatively with crane main control CPU card, hydraulic proportional valve assembly and ship integrated alarm monitoring system. It is widely used as relay interface spare hardware for Liebherr marine deck crane hydraulic automation control system maintenance and retrofit projects.
