Technical Specifications Power Supply: Powered by rack backplane Relay Contact Rating: Rated voltage and current for industrial interlock Operating Temperature:0℃ ~ +60℃ Mounting: 3500 rack slot mounting Housing: Metal rack card casing
Functional Features Multiple independent relay output channels. Relay action controlled by 3500 system alarm and trip logic. Contact status feedback and self-diagnosis function. Isolated relay output to protect system internal circuit. Hot swappable for online maintenance. LED indicators for each relay channel status.
Application Scenarios Alarm and trip relay output for Bently 3500 machinery protection rack. Turbine and compressor safety interlock protection system. Power plant generator set vibration trip signal output. Petrochemical critical rotating equipment alarm interlock circuit. Industrial heavy rotating machinery protection system hardwired trip output.
Performance Parameters Relay action speed: Fast response for trip protection logic Contact isolation: Electrical isolation between system and external circuit Self-diagnosis: Detect relay channel fault
Structural Characteristics Standard rack card metal housing. Internal relay group and drive circuit. Backplane connector for receiving logic signal and power supply. Front panel terminal block for external wiring and channel LED indicators. Front panel locking structure.
Working Principle The module receives alarm and trip logic commands from rack interface module through rack backplane. Internal drive circuit triggers corresponding relay to act, and changes the state of dry contact terminals on front panel. External protection circuit reads contact on/off state to realize sound-light alarm or equipment trip interlock.
Installation Requirements Insert module into assigned slot of 3500 rack and lock front panel. Ensure backplane connector fully engages rack backplane. Connect external interlock wiring to front relay terminals strictly following drawing. Set relay logic via system configuration software. Check channel status indicators after power on.
