Pulse converter / signal converter for encoder signals

Pulse converters are utilized for purposes of electrical isolation, signal level conversion and elimination of interference signals; they also convert HTL to TTL as well as TTL to HTL. The output stages are equipped with the latest driver ICs, and enable signal transmissions along long lengths of cables in conjunction with high output frequencies. Optocouplers isolate the inputs from the outputs. Short-circuits and output stage overload are signalled. The modules can be snapped onto standard mounting rails EN 50 022.
