Category: ADAPT (ESD) Emergency Shutdown Device

The 3701/55 Emergency Shutdown Device, (ADAPT ESD) is a
safety PLC with a graphical logic programming interface and
integrated overspeed detection. ADAPT ESD is 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 that is designed to meet a broad range of
user scenarios and applications. The design offers an
electrical and mechanical package with attention to
reliability and availability as well as extensive self-diagnostics
and compliance to industry standards.
Inputs
Inputs to the system are processed using three CPU modules
to provide triple modular redundancy (TMR). Each CPU
processing module processes two unique speed input
channels, for a total of six speed channels for the system. The
processing modules also monitor an array of 32 discrete (DI)
and process variable (PV) signal inputs. Twelve channels of
this input signal array may be configured either as discrete
inputs or 4-20 mA analog inputs. Remaining channels in the
array are reserved for discrete input signals only.

Compliance
The 3701/55 ESD complies with most applicable
technical regulations and standards.
