Pin Function
Description
1
+12V out, 100mA
2
GND
3
Channel 1, Configurable I/O 1
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 = - 40V DC
Max input = + 40V DC
Max load = 100mA
Max voltage = + 40V DC
