Independent Protection Made Simple:
Diamond-SIS® is a safety-certified single-loop controller, also commonly called a safety trip amplifier or analog safety relay. It provides a simple, cost-effective way to convert process alarms and interlocks into independent, highly reliable low-integrity Protection Layers or safety instrumented systems (SIS).
Cyberproof and designed for process industry applications, Diamond-SIS® can be installed close to the equipment it protects. Each dedicated loop monitors the process and takes action when needed, providing independent protection without the complexity of a PLC-based safety system.
Integrated Diamond-SIS® systems can provide operator controls, alarms, interlocks, low-integrity Protection Layers, and SIS. Local maintenance, startup, and shutdown features simplify operation and support reliable performance throughout the system life.
