Gas & Flame Detection System
Syntel
-
Teledyne Gas & Flame Detection
Syntel is an addressable loop system suitable for use in zone 1 and 2 hazardous areas. The complete addressable loo is fault tolerant operating normally with a short or open circuit. Syntel does not have a CPU, so there is no common failure point. It includes a standard OPC interface and can also be supplied by Modbus allowing easy integration with third party systems.Syntel stores alarm and calibration information in distributed non-volatile memory, hence there is no reliance on a centralized system.Syntel is ideal for installations where there is the possibility for future expansion. The system architecture allows very low cost expansion as cable runs to a central location are not needed.
