SIS system HiaGuard safety instrumented system is a set of safety instrumented systems (SIS) independently developed for industrial automation safety applications. The system has passed T Ü V Rheinland's SIL3 certification and meets the requirements of IEC61508/IEC61511/IEC50156-1 standards. HiaGuard system can be applied to safety related applications that require a complete integrity level of SIL3 or below.

1、 SIS System - HiaGuard Safety Instrumented System Technical Features

1. Easy to operate, with a fully Chinese software interface and user manual;

2. Seamless integration of the system can be achieved with HollySys DCS system;

3. Three redundant system architecture with diagnosis, three redundant system architecture with diagnosis (2oo3D), degraded mode is 3-2-0;

4. Shorten system response time, with a system response time of less than 30ms for a single host cage configuration;

5. Improved availability, a single IO module can meet SIL3 requirements, and IO modules can be redundantly configured to improve availability;

6. The power supply is 1+1 redundant, and the availability rate of the safety circuit can reach 99.999%;

7. SOE accuracy can reach 1ms;

8. Communication modules and I/O modules can be redundantly configured for worry free switching;

9. The diagnostic function with high diagnostic coverage supports online download.

2、 SIS System - HiaGuard Safety Instrumented System Application Fields

SIS System HiaGuard Safety Instrumented System, using a two out of three architecture with diagnostics (2oo3D), is suitable for applications including Emergency Shutdown System (ESD), Fire&Gas System (FGS), Burner Management System (BMS), Emergency Trip System (ETS), Process Shutdown System (PSD), and Critical Process Control.
