AD-KVEX 100 GVD, AD-KVEX 200 GVD
Description
The contact amplifier (switching amplifier) serves preferably the protection of weak sensor contacts or the amplification of binary sensor signals. The AD-KVEX 100/200 GVD provides a logical input signal amplified at a contact output. Typical input signals are reed contacts, signal sensor according to Namur Namur (DIN EN 60947-5-6) or resistance changes. At the output, heavy-duty and potential free contacts are provided. The logical switching direction as well as the line fault recognition is separately switchable for each conduit. The version AD-KVEX 100/200 GVDO has wear-free semi-conductor outputs, which are also galvanically separated via an optic isolation. The device contains an electronic wide range power supply and can operate in a wide supply voltage range.
Application
Pulse recording of water meters or flow monitors for counting through-flow quantities. Amplification and contact protection of weak sensor signals (reed contacts, limit switches, etc.), switching signal transmission in control circuits, switching amplifier for inductive and capacitive proximity switches according to Namur (DIN EN 60947-5-6).
