Masoneilan SVI II ESD Emergency Shutdown Device

Masoneilan SVI II ESD Emergency Shutdown Device

The Masoneilan SVI II ESD automatically captures the partial stroke test (PST) in its non-volatile memory and stores the analysis. The SVI II ESD can capture shutdown events, allow continuous HART communications during a trip, and facilitate local panel annunciation using the built-in discrete outputs.

Description

SVI* II ESD Emergency Shutdown Device


The Masoneilan SVI II ESD automatically captures the partial stroke test (PST) in its non-volatile memory and stores the analysis. The SVI II ESD can capture shutdown events, allow continuous HART communications during a trip, and facilitate local panel annunciation using the built-in discrete outputs. 

Two signatures can be stored, allowing the ValVue* ESD Lookout stand-alone or integrated software to automatically and regularly synchronize its database with field data.

Features and Benefits

•  Universal design helps improve asset utilization

•  Execution of ESD valve PST from any logic solver SIL3 while at 4mA offers efficient operation and ease of use
•  
Emergency Shutdown function independent of partial stroke tests offers versatility in implementing partial stroke tests
•  User friendly setup and operations helps improve testing and valve maintenance efficiency and helps reduce installation costs
•   Captures shutdown events and confirms ESD operations for superior safety integrity level (SIL) of emergency isolation valve applications  
•  Testing methods facilitate safety regulation compliance and extends duration between full proof tests without disturbing process


Common Applications


The Masoneilan SVI II ESD can operate with a 4-20mA signal, 0-24Vdc, or a combination of both. 

The preferred solution is the single 4-20mA because it is SIL3 capable while at 4mA, allowing the device to execute the safety function while active.
