United Electric Controls: Safety Transmitter

Jan. 2, 2014
The One Series is the first SIL 2-certified transmitter designed solely for safety system applications.
Unlike process transmitters that must be adapted for safety use, these transmitters are engineered to protect, giving safety teams simple setup and fast, safer and affordable performance from the start. Units are available in versions that monitor temperature and pressure and features an internal high-speed safety relay for the fastest emergency shutdown, greater affordability than adapting a process transmitter for safety applications, and a higher safe failure fraction that simplifies SIL achievement. The transmitters provide 4-20 mA NAMUR standard output with "I Am Working(tm)" diagnostics. A high-speed safety relay output is incorporated for local alarm or emergency shutdown. Discrete outputs deliver diagnostics and relay status voting logic input to the safety PLC to determine appropriate action. The transmitter is certified for use in SIL 2 safety instrumented systems, and is capable of SIL 3 per IEC 61508. It has configurable self-diagnostics and achieves a safe failure fraction of 98.5%. Instrument response time is <100 milliseconds.>>For more information on this product, click here United Electric Controls www.ueonline.com 617.926.1000
