9.3.2 HANDLER Control Interface - Output Port (O/P)
Example of Output Port (O/P) circuit applies the general connection as Figure 9-2 shows. The
typical Io current is 5mA. The selection of external resistance (Ro-ext) will be varied by
external DC voltage source Vs. Take +5Vdc and +24Vdc as example in below figure, the
selected resistances are 1kΩ and 4.8kΩ.
