The Digital Valve Outputs - Inficon Modul1000 Operating Manual

The digital valve outputs

The 16-pin Phönix-connector box is at the back of the device and marked with
"VALVES".
This connector box is used to control external valves.
They can be divided in 2 groups:
1
The pins 13, 14 and 15 are for the connection of a 24 V-valve; maximum
withdrawable current per output 1A. Their common reference point is pin 16 (GND).
2 8 valves can be connected to the contacts 5 to 12. To be more flexible, these
switched outputs are designed to be floating: the user can connect an external direct
voltage source. It must safely be separated from the power supply network and may
apply maximum 30 V.
The 24V-power supply unit of the Modul1000 can be used for supplying the valves.
The valve switches connect to the 24 V-power supply unit on pin 3. Each valve switch
may be loaded with maximum 0.2 A.
Via this pin, the following valves can be controlled by the Modul1000.
Pin Assignment
24V fuse-protected with F4 (1.6 A) on the interface board. The sum of the
1 maximum supplied current to this pin and the received current from pin 1 on the
outputs PLC OUT and ACCESSORIES has to be lower than 1.6 A.
2 GND
3 Supply voltage external (24V / 30V max.)
4 Not used - can be used as support pin for the external wiring.

6 Output 2
7 Output 3
8 Output 4
9 Output 5
10 Output 6

14 Output 10
15 Output 11
16 GND
*) If control inputs are connected (e.g. valves with integrated electronic circuitry)
instead of solenoid valves, a resistance of 10 kOhm ± 5 % (0.5 W)has to be shunted.
