A traditional emergency shutdown (ESD) system enables reactive protection under emergency conditions, but offers little help to operators and provides little synergy with production control systems.
|
|
A better solution is to integrate safety information and enable seamless monitoring and prediction of critical conditions, opening the path back to normal conditions while securing safety loop integrity. |
Conventional ESD system:
|
|
ProSafe-RS Safety Controller: |
| - Dedicated human machine interface (HMI), dedicated network, dedicated database |
|
| - Enables safety personnel to analyze events retrospectively, but realtime information monitoring through control systems is cumbersome, slow, and limited |
|
|
|
- Information integration:
Common human machine interface and unified event data enables integrated safety management
Alerts operators of critical conditions before they reach emergency |
|
- Safeguarding:
Ensures SIL3 protection in case the process reaches emergency conditions |
|
|
 |
|
 |
|
|
The new groundbreaking ProSafe-RS safety controller ensures a seamless integration of your control system and emergency shutdown system, keeping your operators fully informed of unfolding events. Singlewindow operation through common HMI enables your operators to make effective decisions that bring the process back to a normal condition. The integrated solution helps the operators to minimize hazard even in case of emergency shutdown.

The simplest answer for safety:
single-module SIL3 protection
| - No more theoretical discussion about 1oo2D, TMR, QMR |
|
The most flexible answer for availability:
add-on duplex module
| - Easily scales up to the utmost in availability with Yokogawa's unique pair and spare controller CPU technology |
|
The seamless solution for integration:
single architecture
| - Common human machine interface, common communications network |

The Voice of an Industry Leader
"The technical and commercial challenges for the safety shutdown management concept for this project are
considerable, with full and unambiguous compliance to IEC 61508/61511 international standards. With the selection of
the Yokogawa ProSafe family, we have been able to pursue a truly network based system across various package units."
