According to its maker, the One Series safety transmitter is the first SIL 2-certified transmitter designed solely for safety system applications. Unlike process transmitters that must be adapted for safety use, the One Series is engineered to protect and offer simple setup and fast, safer and affordable performance. The transmitter is available in versions that monitor temperature and pressure. Applications include IEC 61508 SIS systems, Voting Logic systems (2oo3), critical safety applications such as common mode failure reduction, and API 682 seal support systems. Features include a 4 mA to 20 mA NAMUR standard error indicating output with exclusive “I Am Working” diagnostics, high-speed safety relay output, and discrete outputs. 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 98.8%. Instrument response time is less than 100 ms. A datasheet is available at http://www.ueonline.com/st/download_one.pdf
