AD-KI 100 GS, AD-KI 100 GS-O


The contact protection pulse relay (switching amplifier, pulse shaper) serves preferably the protection of weak transducer contacts or the amplification of binary transducer signals. At the same time it converts the prepared input signals to output pulses with constant, adjustable lengths (via trimmer at the front). Typical input signals are reed contacts, signal generator according to Namur (DIN EN 60947-5-6), TTL level, voltage signals or resistance changes. Heavy-duty and potential-free contacts are available at the output. The version AD-KI 100 GSO has wear-free transistor outputs, which are also galvanic separated via opto-coupler. Further, the device has an electronic wide-range power pack, which supplies the AD-KI 100 GS(O) energy-efficient from a wide supply voltage range.
