3.2 DIGITAL OUTPUTS

The PLC300 has eight insulated and protected digital outputs, besides a fast PWM
output that can generate pulses of up to 300 kHz with variable duty cycle from 0 to
100 %.
This output can also be used as a standard digital output, but it is not protected.
The circuit of the digital outputs must be externally powered by a supply of 24 Vdc,
connected to the pins VBB(+) and GNDBB(-).
The outputs DO1 to DO8 are of PNP
mA each.
DO9 is a Push-Pull
(2)
(1) PNP Output: activate load connected to GNDBB.
(2) Push-Pull Output: Bi-directional, i.e., activates the load connected to GNDBB or to VBB.
