Bently Nevada Corporation’s latest product, the 3701/55 ADAPT (ESD) Emergency Shutdown device, features an advanced 323174-01 CPU module, marking a new evolution in industrial safety control technology. This unit is designed to monitor and protect rotating equipment such as steam turbines, gas turbines, water turbines, expanders and other process equipment, ensuring the safety and reliability of industrial processes.
​Advanced technology, excellent performance:
The 323174-01 CPU module is the heart of the ADAPT ESD system and uses Triple Module redundancy (TMR) architecture to provide high performance data processing capabilities. The module is capable of handling all 32 discrete inputs and 12 analog inputs while monitoring two speed inputs, providing a total of six speed input channels for the system, optimizing decision time from input to output, providing 2ms logic processing time and 8ms relay switching time.
​Flexible configuration and easy maintenance:
In the input signal array of the 3701/55 ADAPT ESD system, 12 channels can be configured as discrete inputs or 4-20mA analog inputs, and the remaining channels are reserved for discrete input signals only. The relay output module has five configurable relays for a variety of applications. The Bently Nevada Monitor configuration software provides a graphical interface that makes it easy for users to configure relay logic.
