Safety Instrumented System Features Compact Terminal Boards

July 27, 2011
Compact terminal boards will be released in June and ProSafe-RS R3.01 will be released in July.

Yokogawa Electric Corp. announces the development of an enhanced version of the ProSafe-RS safety instrumented system that is used to ensure the safety of plant operations. This new version, ProSafe-RS R3.01, features input modules that can directly receive voltage signals from temperature sensors as well as software that restricts the operations performed by individual engineers and records a log on their activities.

In addition, new compact terminal boards have been developed for use with the ProSafe-RS safety instrumented system. The compact terminal boards will be released in June and ProSafe-RS R3.01 will be released in July.

Yokogawa has developed new modules and new terminal boards that are both reliable and compact and software that can improve operational safety. These new modules receive signals from mV, thermocouple (tc), and RTD sensors. The modules do not require a signal converter to process the voltage signals from a temperature sensor. This enables a more compact design.

This software restricts the operations that can be performed by the individual engineers who are operating the ProSafe-RS safety instrumented system and records a log on their activities. These DIN rail-mounted ProSafe-RS terminal boards that connect to cables from field devices are approximately 60% smaller than Yokogawa’s previous terminal boards. These newly developed boards can be installed either horizontally or vertically.
