Bently Nevada 125720-01 Channel Relay Module 3500/32M

Functional Description

125720-01 is a Relay I/O Module developed by Bently Nevada. It is a part of 4-Channel Relay Module. The system consists of full-size module with four relay outputs. In any of the slots to the right of the Rack Interface Module, any number of 4-Channel Relay Modules can be installed. The outputs can be independently programmed to perform required voting logic. Each relay has Alarm Drive Logic. The Alarm Drive Logic is programmed with AND and OR logic and can accept alarming inputs (alerts and dangers) from any monitor channel or combination of monitor channels in the rack. The 3500 is used in this Alarm Drive Logic programming.

LEDs

• OK LED: Illuminated when module is functioning properly.

• TX/RX LED: Transmit and Receive. Flashes to indicate proper communications between this module and other modules within the rack.

• CH ALARM LED: Illuminated when the Relay Channel is in an alarm state.

Environmental

• Sealing: Epoxy-sealed

• Arc Suppressor: 250 Vrms, installed as standard.

• Contact Life: 100,000 cycles at 5 A, 24 Vdc or 120 Vac.

• Operation: Each channel is switch selectable for Normally De-energized or Normally Energized.

Features

• It serves as an interface between the control system and external electrical loads or devices.

• The module features multiple relay circuits that enable the switching of electrical signals, allowing the control system to activate or deactivate the corresponding electrical loads. It acts as a relay control center, receiving control signals from the control system and providing reliable switching operations based on the specified logic and requirements.

• The module is designed to ensure compatibility and seamless integration with Bently Nevada's system architecture and other components. It may utilize standard communication protocols and interfaces, making it easy to incorporate into existing control systems.

• The module may also feature diagnostic capabilities, allowing for the monitoring of relay status and health. This ensures early detection of any abnormalities or faults in the relay circuits, enabling proactive maintenance and minimizing the risk of system failures.

Functional Features Independent Programming: As a full-height module, it can provide four relay outputs. Each output can be programmed independently to execute the required voting logic, and the actions of the relays can be set flexibly according to different monitoring conditions and requirements. Alarm Drive Logic: Each relay contains "alarm drive logic", which can be programmed using "AND" and "OR" logic, and can utilize the alarm inputs (alarm and danger signals) of any monitor channel or combination of monitor channels in the rack. It can be programmed through the 3500 rack configuration software to meet the needs of specific applications.

Technical Parameters Dimensions and Weight: The dimensions are approximately 2.5 cm × 11.2 cm × 24.2 cm, and the weight is approximately 0.5 kg. Others: The shipping weight is approximately 2 kg, and the brand-new product comes with a 1-year warranty.

Application Areas It is widely applied in industrial fields that require precise monitoring and protection of equipment such as rotating machinery, such as the power, petrochemical, metallurgical, and papermaking industries. It can be used in conjunction with other monitoring modules of the 3500 series to monitor parameters such as the vibration, displacement, and temperature of the equipment. When the monitored parameters exceed the set thresholds, signals are output through the relays to trigger the alarm device or take corresponding protective measures, such as equipment shutdown, etc., to ensure the safe and stable operation of the equipment.
