BENTLY NEVADA 3500/32 4 Channel Relay Module PWA 125712-01 L
BENTLY NEVADA 3500/32 is rack plug-in marine 4-channel relay module, designed for Bently Nevada 3500 series machinery protection monitoring system, widely fitted onboard offshore vessels, heavy-lift ships and industrial marine platforms for machinery alarm and trip interlock signal output. This marine relay module provides four independent SPDT potential-free relay contacts, receiving alert and danger status signals from vibration, displacement and speed monitor cards, executing configurable AND/OR voting logic to trigger alarm or equipment trip protection for rotating machinery.

The marine relay module integrates embedded alarm drive logic, epoxy sealed relay contacts, surge suppression circuit and watchdog monitoring function, each channel can be individually configured via 3500 rack configuration software to realize network fault logging and emergency cut-off interlock supervision for marine turbine, pump and compressor equipment. Its relay switching & hardware diagnostics function continuously monitors 24V DC power supply, backplane bus signal and contact integrity, detects coil burnout, contact degradation and communication loss, transmits relay module fault alerts and machinery protection network status to vessel AMS alarm console. The relay switching & hardware diagnostics ensures reliable safety trip circuit control for Bently Nevada 3500 marine machinery protection monitoring system. It enables reliable marine 3500/32 relay module operation under heavy vessel vibration and salt mist marine environments.

This Bently Nevada 3500/32 relay module delivers stable marine machinery protection relay performance inserted into the 3500 monitor rack. The relay switching & hardware diagnostics adopts marine-grade PCB assembly with EMC shielding against electromagnetic interference and mechanical shock. Marine condition monitoring technicians rely on marine 3500/32 module operation to test relay switching action, verify contact performance and check network configuration during routine maintenance. It adopts standard rack plug-in mounting design for straightforward spare replacement and minimal marine machinery protection system downtime. Internal circuit boards use conformal coating to protect electronic components against salt mist, condensation and temperature fluctuation. It works cooperatively with 3500 monitor rack, vibration monitoring cards and ship integrated alarm monitoring system. It is widely used as machinery protection relay spare hardware for Bently Nevada marine vessel rotating machinery vibration monitoring and safety protection control system maintenance and retrofit projects.
