One Series Safety Transmitter is First SIL-Certified Transmitter Designed Solely for Safety Systems

United Electric Controls推出了一个系列安全发射器，这是第一个仅专为安全系统应用而设计的SIL 2认证发射器。与成本高昂的是，必须适应安全使用的过度复杂化的工艺发射机，该系列是为保护而设计的，从一开始就为安全团队提供了简单的设置，快速，更安全，更便宜的性能。

新的One系列安全发射器有监测温度和压力的版本。它的功能包括“独家设计，意味着更少的滋扰旅行，更高的安全性和生产力，是最快紧急关闭的内部高速安全继电器，比适应安全应用程序的过程发射机更高的可负担性以及更高的安全故障分数，简化了。Sil Achievement。

The One Series transmitter provides 4-20 mA NAMUR standard output with exclusive “I Am Working™” diagnostics. A unique, 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.

Additional features include:

•一个大数字显示,提供过程riable, status, self-diagnostics and field programming information

•100％可编程的固态继电器（开关设置点和死带）

•有效替换量规，发射机和开关以减少潜在的泄漏路径

•获得SIL 2植物安全应用的认证，可提供FMEDA报告

• Worldwide hazardous location approvals for Class I, Divisions 1 & 2 (Zones 0, 1 & 2)
