November 6, 2011 – Pepperl+Fuchs added four power supplies to the company’s family of K- and H-System intrinsic safety solutions. Single-channel KCD2-STC-Ex.1ES and KFD2-STC4-Ex1.ES transmitter power supplies are assembled to the 35 mm DIN mounting rail with power rail. HiC2025ES and HiD2025ES transmitter power supplies are mounted on prewired termination boards. These modules provide internal diagnostics information using a single failure signal, and are designed for intrinsically safe applications up to SIL 3 according to EN61508.
KCD2-STC-Ex.1ES and KFD2-STC4-Ex1.ES modules supplement the company’s K- System – a comprehensive family of approximately 150 intrinsically safe isolator modules and signal conditioners that solve a wide array of intrinsic safety application needs. They are just 12.5 and 20 mm wide, respectively, and offer active and passive 4…20 mA output signals as well as 1…5 V for the control level.
The HiC2025ES and HiD2025ES transmitter power supplies are part of the company’s H- System intrinsic safety solutions. These two space saving modules are 12.5 and 18 mm wide respectively and are both compatible with existing termination boards in the system.
