Bently Nevada 3701/55-01-01 ADAPT ESD Relay Output Module

Description:The 3701/55 Emergency Shutdown Device, (ADAPT ESD), is a safety PLC featuring a graphical logic programming interface and integrated overspeed detection. It is specifically designed for emergency shutdown of rotating machinery such as steam, gas, and hydro turbines, expanders, and other process equipment. ADAPT ESD is a compact, standalone, triple-redundant safety shutdown device, designed to meet a broad range of user scenarios and applications. The design emphasizes reliability, availability, extensive self-diagnostics, and compliance with industry standards. Inputs:Inputs to the system are processed using three CPU modules to provide triple modular redundancy (TMR). Each CPU processing module handles two unique speed input channels, resulting in a total of six speed channels for the system. Additionally, the processing modules monitor an array of 32 discrete (DI) and process variable (PV) signal inputs. Out of these, twelve channels of the input signal array may be confi
