Description
Bently 149986-013500 33
Technical Specifications
- Part Number: 149986-01
- Module Type: 3500/33 16-Channel Relay Monitor
- System Compatibility: Bently Nevada 3500 Framework
Key Features
- High-Density Output: Consolidates 16 independent relay outputs into a single module footprint.
- Flexible Logic Programming: Supports AND, OR, and Inhibit voting logic using alarm states from any channel in the rack.
- Real-Time Alarm Display: Capable of displaying real-time alarm information to facilitate timely fault handling.
Application Scenarios
Deployed in critical rotating machinery protection systems requiring numerous discrete trip and alarm signals, such as large steam turbines and multi-stage compressors.
Performance Parameters
- Contact Rating: Standard industrial relay ratings for driving PLC inputs and trip circuits.
- Response Time: Millisecond-level actuation upon alarm trigger.
Material Composition
High-reliability electromechanical relays housed in a ruggedized, flame-retardant industrial enclosure.
Structural Characteristics
Standard full-height 3500 module form factor featuring 16 front-panel status LEDs and rear terminal connections for external wiring.
Working Principle
Continuously polls the 3500 backplane for alarm statuses. An internal microprocessor evaluates the user-defined logic and energizes the corresponding relay coil when the specified conditions are met.
Installation Requirements
Can be placed in any available slot to the right of the Transient Data Interface (TDI) module. Meticulous wire routing and strain relief are mandatory due to the high number of external connections.
Usage Precautions
Carefully map the 16-channel logic in the configuration software to prevent cross-wiring errors. Regularly inspect the terminal block for tightness, as vibration can loosen connections over time.
