معرفی محصول زنربریر مدل Z787 F دو کاناله میباشد ولتاژ تغذیه 27VDC و 10mA نوع سیگنال آنالوگ حداکثر ولتاژ 250v حداکثر آمپر 93mA در مناطق ضد انفجار مورد استفاده قرار میگیرد توضیحات محصول Feature 2Channel DC version, positive polarity Working voltage 26 5 V at 10 μA Series resistance max 341 Ω Fuse rating 50mA DIN rail mounting Replaceable back up fuse With diode return Function The Zener Barrier prevents the transfer of unacceptably high energy from the safe area into the hazardous area The zener diodes in the Zener Barrier are connected in the reverse direction The breakdown voltage of the diodes is not exceeded in normal operation If this voltage is exceeded, due to a fault in the safe area, the diodes start to conduct, causing the fuse to blow The Zener Barrier has a positive polarity, i e the anodes of the zener diodes are grounded Additionally this Zener Barrier is equipped with a replaceable fuse The Zener Barrier is for evaluation of signals from the hazardous area The diodes of diode return prevent a current into the hazardous area, therefore the current assumption for intrinsic safety calculations is zero Depending on the application, increased or decreased intrinsic safety parameters apply for serial or parallel connection For the detailed parameters refer to the Zener Barrier certificate Application examples can be found in the system description of the Zener Barriers
