Digital input - Connect to GND
to activate, or leave floating (or
unconnected) to deactivate.
Digital output - Uses an open
drain NFET transistor with the
source connected to GND. If
used with an external relay,
a diode must be connected
in parallel with the load, for
protection against voltage
transients.
Min input = – 40 V DC
Max input = + 40 V DC
Max load = 100mA
Max voltage = + 40 V DC
