Introduction
The component with part number 3500/22-01-01-01 is a monitoring module within the Bently Nevada* 3500 Machinery Protection System. This part number refers to the 3500/22 4-Channel DC Input Module.
This module is designed to monitor up to four DC voltage or current signals from external transducers and convert them into usable data for the monitoring system. Its primary function is to provide continuous surveillance of non-vibration process parameters, such as temperature, pressure, flow, or position, and to provide alarm and shutdown functions to protect critical industrial machinery.
*Bently Nevada is a part of Baker Hughes.
Parameters
The following table outlines the key technical parameters for the 3500/22-01-01-01 monitor.
| Parameter | Specification |
|---|---|
| Part Number | 3500/22-01-01-01 |
| Module Type | 4-Channel DC Input Module |

Application Scenarios
The 3500/22 DC Input Module is deployed to monitor various auxiliary process parameters that are essential for the safe and reliable operation of machinery. Key application scenarios include:
Temperature Monitoring:
Accepting signals from temperature transmitters (4-20 mA) monitoring bearing metal temperatures, lube oil temperatures, or motor winding temperatures.
Pressure Monitoring:
Monitoring critical pressure points such as lube oil pressure, seal oil differential pressure, or fuel gas pressure to ensure they remain within safe operating limits.
Position and Displacement Monitoring:
Receiving DC voltage signals from potentiometers or LVDTs (Linear Variable Differential Transformers) to monitor valve positions, actuator positions, or thermal growth.
General Process Monitoring:
Interfacing with any transducer that provides a standard DC voltage or current output, allowing for the monitoring of flow, level, or speed.
Integrated Machinery Protection:
Working in conjunction with other 3500 modules (like vibration monitors) to provide a comprehensive protection scheme. If a monitored parameter (e.g., high bearing temperature) exceeds its setpoint, the module can trigger an alarm in the control room and, if necessary, a Danger shutdown to protect the machine from damage.
