3 CONNECTIONS
3.1 DIGITAL INPUTS
The 10 insulated digital inputs must be excited by an external source of 24 Vdc. The
inputs are bidirectional, which means the input common can be connected to either
the GND or the VDC of the supply.
The DIs 9 and 10 are faster and can read a signal of up to 100 kHz, and they can also
operate as encoder input. The other DIs can count up to 4 kHz.

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(1) type and can provide a current of up to 500
mA each.
DO9 is a Push-Pull(2) output, PWM type, and can supply up to 100 mA.
(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.

3.5 ENCODER INPUT
The PLC300 features an insulated input for differential encoder, with its own supply
of 5 or 12 V. The maximum frequency of the pulses is 100 kHz. Maximum length of
the encoder cable: 30 m.
An internal insulated supply of 5 or 12 Vdc, with capacity of up to 300 mA, is available
for the encoder. The selection between 5 or 12 V must be done in the PLC setup.
The default value is 5 V.

Figure 3.5: Encoder connection
24 V Encoder : You can connect a 24 V encoder, since externally powered and only
signals A, B, and Z are used.
The 0 V of the encoder must be connected to 0 V of XC3 (pin 8)
A, B and Z signals are NOT tolerant to 24 V.
The signals A, B and Z can be used to fast counting and interrupts, also in 24 V.
Encoder PNP: if an encoder with PNP outputs is used, resistors of 1 K ohm must be
connected from the used signals to the 0 V.
E.g.: PNP encoder with A and B signals.
