transmitter power suppliesPepperl+Fuchs has added four new 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. CD2-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 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.
