Signal Level Sources
The following signal levels apply to the input and output signals.
Input level
Low 0 to + 5 V
High +12 to +30 V
Affects IN1 to IN10
IN1 to IN10 not active
IN1 to IN10 is activated
Affects IN_STOP
IN_STOP active
IN_STOP not active
= emergency off
= no emergency off
Output
level
0
V
24
V
Meaning of OUT_READY 0 V = not ready
24 V = ready
Meaning of
OUT_LINE_END
0 V = no response possible
24 V pulse, duration 100 ms
= end of pulse output
OUT_TEMP_PLC
0 V = temperature dispensing
24 V = temperature dispensing
material–fault
material–normal
OUT_FAULT_PLC
0 V = process fault
24 V = process normal
Output signal
0 V = no dispensing sequence
24 V = dispensing sequence active
channels 1–4
The signal levels / potentials of the binary input and output signals can be provided by the internal power supply of
the PICO controller or by a separate source (PLC, power supply unit, or similar device).
The switch stages of the binary input and output signals of the PICO controller are galvanically isolated from the
power supply at the factory. Depending on which source of potential is chosen, the following instructions must be
complied with when connecting to the 25-pin D-subconnector (Channels 1 to 4).
