Hazardous area I/O survives gas and dust
A new distributed I/O system is designed for direct use in gaseous and dusty atmospheres up to zone 1 as well as in zone 21.
Siemens Automation and Drives has developed a distributed I/O system for potentially explosive environments The Simatic ET 200iSP (iSP stands for "intrinsically safe for the process industry") is designed for direct use in gaseous and dusty atmospheres up to zone 1 as well as in zone 21
Because the system has both a redundant Profibus and a redundant power supply, the production process is able to continue following a failure or fault thanks to a "hot standby" switch-over to the redundant Profibus line within 100ms.
High-availability Simatic S7-400H controllers are used for this purpose.
"Warm standby", a software solution for standard S7 controllers, attains switching times of up to 1s.
The intrinsically safe and modular ET-200iSP system is designed for particularly easy installation and engineering.
