Product Introduction & Positioning
The BENTLY 136719-01 is an Earthing I/O Module within the Bently Nevada 3500 Series, engineered specifically to provide intrinsic safety by isolating and managing grounding signals from connected vibration sensors and associated hardware. Its functionality ensures safe operation by converting these grounding signals into stable, compliant outputs suitable for hazardous area installations. The module supports multiple relay outputs that can be independently programmed, facilitating customizable control and signaling schemes within the overall monitoring system. Equipped with various communication interfaces such as LAN, serial, and digital IO, the 136719-01 integrates seamlessly into large automated control networks. It is compatible with 12 to 48 VDC input power and designed for easy physical installation via rail or panel mounting, supporting industry engineers aiming to enhance sensor system safety and signal integrity in harsh operational settings.
Key Technical Features & Functional Benefits
The BENTLY 136719-01 excels in conditioning and safeguarding grounding signals with its ability to process both analog and digital inputs. It incorporates four relay outputs that engineers can program individually to implement diverse control logics or alarm functions, enhancing system responsiveness. Its communication versatility spans LAN, serial ports, and digital IO interfaces, simplifying integration with remote master stations or supervisory control and data acquisition (SCADA) systems.
Operationally, the module is built for durability, withstanding operating temperatures from -40°C to +82°C and offering an IP67 protection rating that shields it from dust and water ingress. Its anti-interference design isolates analog and digital grounds through a “busbar separate routing” methodology, effectively minimizing noise that could degrade sensor signals. The module also supports motion control applications, providing precise closed-loop feedback mechanisms ideal for servo motors and hydraulic actuators, broadening its functionality beyond mere signal conversion.
