Sample outputs
F201 laser’s optoisolated, bi-directional switched outputs can drive small loads (50 mA max), PLC inputs,
or relays that can control higher current loads. Figure below illustrates one method of controlling a remote
warning lamp using power supplied by F201 laser’s +24 VDC Auxiliary Power output. Remember to size
current-limiting resistor, R1, so that the current draw does not exceed 50 mA.
Figure 4-12 F201 laser output driving warning lamp.
Figure below illustrates a method for controlling a higher voltage, higher current load by using a 24V
control relay. Ensure that the relay coil’s pull-in current does not exceed 50 mA. A diode or surge sup-
pressor must be installed across the relay coil to prevent voltage spikes from damaging F201 laser outputs.
