The electronic overspeed detection system of the Bently Nevada 3500 Series Mechanical Monitoring system is a highly reliable, fast response redundant tachometer system designed for overspeed protection of machinery. Among them, the 3500/60 module is one of the key components in the system, providing temperature monitoring capabilities, the ability to accept resistance temperature detector (RTD) and thermocouple (TC) temperature inputs, adjust these input signals, and compare them with user-programmable alarm setpoints.

The 3500/60 module provides the same functionality as the 3500/61 module, but the 3500/61 module provides a recorder output for each of its six channels, while the 3500/60 does not. Users can program these modules using 3500 configuration software to perform RTD or TC temperature measurements. The module also has an internal barrier function that provides 250V DC interchannel isolation to protect against external interference.

In particular, the 136711-01 is a specific model of the 3500/60 module, which is an I/O module with internal barriers and internal terminals. This module is designed to provide safety in hazardous areas, ensuring the explosion-proof performance of the sensor system connected to the 3500 system. The 136711-01 module has an input impedance of 10 MΩ per pin input and a power consumption of 7 watts, which is suitable for receiving 1 to 6 RTD or TC sensor signals.

In addition, the 3500/60 module has several advanced features such as diagnostic reports for real-time status and fault information, as well as a watchdog timer to monitor module activity and detect any faults or errors. The module’s operating frequency range is 0~400Hz, and the main circuit adopts AC-DC-AC circuit to ensure high precision analog-to-digital conversion in various industrial applications.

In general, Bently Nevada’s 3500/60 modules, and model 136711-01 in particular, are integral components in industrial monitoring and control systems, supporting mechanical monitoring with their high precision, high reliability and powerful features.
