Product Details:

The BENTLY NEVADA 135489-01 internal barrier I/O module is a special 4-channel monitor board with built-in intrinsic safety barriers for the Bently Nevada 3500 machinery protection rack system. This hazardous area monitor eliminates the requirement for external safety barriers, simplifying wiring layout and reducing overall system installation cost. The 3500 system module can directly connect to proximity probes, velocity sensors and accelerometers installed in explosive hazardous zones, safely transmitting vibration and shaft position signals back to the 3500 rack located in safe control rooms. It maintains high precision signal measurement and stable data transmission, supports configuration of alert and danger alarm thresholds for rotating machinery parameters such as radial vibration, thrust position and differential expansion. The module supports hot swapping without shutting down the whole protection system, and continuous self-diagnosis function detects wiring breaks, short circuits and module faults in real time, feeding fault status to rack configuration software and status LED indicators. It complies with intrinsic safety certification standards, suitable for flammable gas environments in petrochemical, offshore oil and gas industries, providing reliable machinery protection for compressors, steam turbines and other critical rotating equipment working in hazardous locations.
