Description
Bently 149986-02
Technical Specifications
- Part Number: 149986-02
- Module Type: 3500/32M Quad Relay
- Outputs: 4 Independent SPDT Relays
- Logic Support: AND, OR, and Inhibit logic
Key Features
- Flexible Logic Programming: Each relay can be independently configured to trigger based on complex combinations of vibration, displacement, or system alarms.
- High-Capacity Contacts: Industrial-grade relays capable of directly driving PLC inputs or intermediate trip relays.
- Hot-Swappable: Can be replaced without disrupting the monitoring framework.
Application Scenarios
Deployed in critical machinery protection systems to provide the final hardware-level trip and alarm outputs required by API 670 standards and plant safety protocols.
Performance Parameters
- Contact Rating: Typically 3A @ 240 VAC / 30 VDC
- Response Time: Millisecond-level actuation upon alarm trigger
Material Composition
High-reliability electromechanical relays housed in a ruggedized, flame-retardant industrial enclosure.
Structural Characteristics
Full-height module form factor. Features four front-panel status LEDs indicating the energized state of each relay, and rear terminal connections for external wiring.
Working Principle
Continuously monitors the alarm status of designated channels via the backplane. The internal microprocessor evaluates the user-defined logic (e.g., “Vibration High AND Vibration High”) and energizes the corresponding relay coil when the condition is met.
Installation Requirements
Can be installed in any available slot to the right
