MODEL FL157A LINE DRIVER

DESCRIPTION The Model FL157A conditions magnetic speed pickup transducer signals and buffers them, allowing long transmission lines to be driven. Transformer coupling of the input signal allows up to 1000V RMS isolation between the transducer and monitoring equipment. Two or four identical outputs are available, and shorting any output will not affect the others. The unit is mechanically and electricallycompatible with Encore's other FlexiLine DIN-rail mounted instrumentation.
