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.
*) 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.
Pin
Assignment
1
24V fuse-protected with F4 (1.6 A) on the interface board. The sum of the
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.
