1-channel isolated barrier
-
24 V DC supply (Power Rail)
-
Voltage input 0 V … -20 V
The Voltage Repeater from Pepperl+Fuchs is an essential component in the field of intrinsic safety barriers, designed for isolating and amplifying voltage signals in hazardous environments. These devices are critical for ensuring reliable communication and control in applications where safety and regulatory compliance are paramount, such as in chemical processing, oil and gas industries, and other areas with explosive atmospheres.
This 1-channel isolated barrier operates with a 24 V DC power supply and can accept voltage inputs ranging from 0 V to -20 V. The design of the Voltage Repeater ensures that the integrity of the signal is maintained while providing necessary isolation from potentially dangerous voltages. This functionality helps to protect sensitive equipment and personnel operating in hazardous zones, enabling safe and efficient system operation.
