LED or other output
The two I/O lines, pins 2 & 10, can drive an external device such as solenoids, LED’s,
or switches. The bidirectional I/O’s are switches to ground internally, and therefore
need to be connected to the +V of the power supply. Below is a recommended
connection for lighting an LED with 20 mAmps:
Upon entering command /1J0R, both pins 2 & 10 will output 1 Amps. The 1.2k ohm
resistor will limit the current to 20 mAmps into the LED. Select any ohm value to
limit your current based on the device that is connected to the output. I/O’s are
24VDC tolerant.
