Technical Specifications Power Supply: Powered via rack backplane Channel Quantity: 16 relay channels Operating Temperature:0℃ ~ +60℃ Mounting: 3500 rack slot mounting Housing: Metal rack card casing
Functional Features 16 independent relay output channels for multi-point interlock demand. Dry contact output controlled by system alarm and trip logic. Built-in channel self-diagnosis to detect relay and wiring fault. Electrical isolation between internal system circuit and external field circuit. Hot swappable design. Independent LED indicator for each relay channel status.
Application Scenarios Multi-channel alarm and trip relay output for Bently 3500 protection rack. Steam turbine and gas turbine multi-point protection interlock system. Power plant large generator set multi-condition alarm output. Petrochemical plant multi-measuring point compressor protection system. Heavy industry large rotating equipment multi-channel hardwired interlock.
Performance Parameters Relay response speed: Fast action for protection trip signal Channel isolation: Isolation between each relay channel Fault diagnosis: Detect relay coil and contact fault
Structural Characteristics Standard rack card metal shielding housing. 16 groups of relay components and drive circuit integrated inside. Backplane connector for power and logic signal transmission. Front panel terminal blocks for external field wiring, with channel LED indicators. Front panel locking mechanism.
Working Principle The module obtains protection logic commands from rack interface module through rack backplane. Internal drive circuit triggers corresponding relay according to configuration logic, changes dry contact state on front terminals. External control system uses these contact signals to trigger alarm, shutdown and interlock action for rotating machinery.
Installation Requirements Insert module into designated slot of 3500 rack and lock front panel. Confirm backplane connector fully connected with rack backplane. Wire external interlock circuit to front relay terminals following schematic. Configure each channel logic through 3500 configuration software. Check all channel status indicators after power on.
