3.6 General Purpose Digital Output
Leadshine SMC6000 provides 8 isolated and 16 non-isolated general purpose digital outputs.
3.6.1. Isolated General Purpose Digital Outputs
The isolated general purpose outputs adopt OC (open collector) output circuit. Digital output OUT1 and OUT2 use
MOSFET and they can withstand up to 1A current for relay. See figure 3-8 for interface circuit of OUT1 and OUT2.
Digital output OUT3~OUT8 adopts ULN2803 and the output current is limit to 60mA. See figure 3-9 for interface
circuit of digital output OUT3-OUT8. The pin assignments of isolated digital outputs are shown in table 2-3.

Typical connections of general purpose digital outputs to different components are shown as follows:
1) Connections to LED
When connected the digital output to a LED, series a resistor between the power input and the LED to limit the
current to approx 10mA. The resistance is depending on the external power voltage. For example, 2K series resistor
is suitable for 24VDC power input. See figure 3-10 for how to connect the LED and series resistor.
