• Programmable Alarm Logic: 6 independent relays with configurable alert/danger setpoints, latching/non-latching operation, and voting logic for customized protection responses.

• Data Logging & Diagnostics: 200-entry event log (alarms, trips, faults); waveform and trend data storage for predictive maintenance analysis.

• Industrial Communication: Seamless integration with DCS/PLC via Modbus RTU/TCP, Ethernet, or serial interfaces for remote monitoring and control.

Operational Features

• Local Configuration & Display: Front-panel LCD/keypad for on-site setup, parameter adjustment, and real-time data viewing (vibration, temperature, speed, alarm status).

• Sensor Compatibility: Supports all Bently Nevada sensors (proximity, velocity, ICP acceleration) and standard RTD/thermocouple temperature sensors for flexible deployment.

• Isolated I/O: Galvanic isolation between input channels, power, and communication ports to prevent ground loops and electrical noise interference.

• Hot-Swappable Relays: Relay modules can be replaced without powering down the unit, minimizing maintenance downtime.

Product Positioning

• Cooling tower fans, pumps, blowers, and small compressors in power, oil and gas, and petrochemical industries.

• API 670-compliant machinery protection for non-critical but essential rotating equipment.
