Bently 135489-01 Control System – Intrinsically Safe Interfaces
The Bently 135489-01 Control System delivers critical safety functions for industrial environments where explosive atmospheres exist. Designed as part of the 3500 series protection systems, this module provides galvanic isolation for vibration monitoring sensors in applications like turbine monitoring or compressor control. While not a standalone safety system, it acts as a crucial interface between hazardous area transducers and control room equipment.

Field Applications & Compatibility
This module works within complete 3500 rack systems commonly found in oil & gas processing plants and power generation facilities. We’ve supported installations integrating it with 3500/22M monitoring cards and 3500/42M communication modules. Typical applications include:
- Gas turbine vibration monitoring systems
- Refinery compressor protection setups
- Steam turbine condition monitoring
Our inventory includes complementary 3500 series components like 3500/15 power supplies and 3500/32 displacement transducer interfaces. For legacy installations, we can source 1900 series compatibility modules when needed.
