6.1 Voltage supply
24 V DC input:
The voltage supply is carried out using a connecting cable from the Pfeiffer Vacuum
accessories or using a cable provided by the customer.
●
Pin 1
: +24 V DC
●
Pin 15
: Earth (GND)
24 V DC output / pin 7:
Inputs 2 to 6 are activated if they are connected to pin 7 (active high) with +24
VDC. They can also be activated via an external SPS. The functions are deactivated by "SPS high lev-
el" and by "SPS low level".
● PLC High level: +13 V to +33 V
● PLC Low level: -33 V to +7 V
● Ri: 7 kΩ
● I
max
< 200 mA
6.2 Inputs
The digital inputs switch various electronic drive unit functions. Inputs are assigned with functions ex-
factory. You can configure them via the RS-485 interface and the Pfeiffer Vacuum parameter set.
