(2) Digital output interface DO-1
A lamp, relay or photocoupler can be driven. Provide a diode (D) for an inductive load, or an inrush
current suppressing resistor (R) for a lamp load. (Permissible current: 40mA or less, inrush current:
100mA or less) A maximum of 2.6V voltage drop occurs in the servo amplifier.
