OPERATION
Model FL157A
Line Driver
1) Connect a 24V power supply capable of delivering at least 50mA to the +24V and COM terminals.
2) Connect the FL157A HI and LO input terminals to your frequency signal source.
3) Connect the Output terminals to your load.
The FL157A output is +5V normally, and drops to 0V when triggered. The FL157A triggers on input voltage rising above a preset threshold.
When using the FL157A with a narrow pulse (such as a 1/rev pickup) you may need to exchange the input signal connections (+ and -) for proper operation. If your pulse is negative-going and narrow, connect the signal to –IN and signal common to +IN. The internal isolation transformer keeps
–IN separate from COM terminals.
