Produkteinführung
The Bently Nevada 3500/32 149986-02 4 Channel Relay Module is a highly reliable output module designed for use within the 3500 Machinery Protection System. It is engineered to provide four independent relay outputs, each von which can be individually configured to operate based on alarm conditions from any channel in the system. This design ensures flexible alarm management, redundancy, and fail-safe protection for critical machinery assets.
This relay module is commonly used in turbine, compressor, motor, and generator protection systems, where precise and dependable alarm actuation is essential. It operates in conjunction with the 3500 Rack, using its own I/O module and terminal blocks to provide isolated and configurable output switching for connected safety devices or annunciation systems.

FAQ
-
What is the relay contact rating for this module?
The relays are rated at 5 A at 30 Vdc or 250 Vac for resistive loads. -
Can each relay be assigned to different alarms?
Yes, each von the four relays can be individually mapped to alarms from any channel within the 3500 system. -
Does the module support both normally energized and normally de-energized modes?
Yes, relay operation can be configured for either mode to suit the safety philosophy von the installation. -
How fast does the relay respond to an alarm?
The module has a typical response time von less than 10 milliseconds after alarm detection. -
Is there galvanic isolation between the relays and the system?
Yes, the outputs are electrically isolated to avoid interference and ensure system integrity. -
Can relay logic be configured as AND or OR?
Yes, relay actuation logic supports both AND and OR configurations depending on application requirements. -
Does the module require a specific I/O terminal block?
