Switch-off characteristic
For the automatic switch-off of an output three ranges can be distinguished (typical values; see also figure 3):
output current to rated current
range
input voltage > 20 V
input voltage < 20 V
input voltage > 30 V
Technical data
Input variables
Rated input voltage:
DC 24 V
Working voltage range:
DC 20.4...30 V
Connection threshold:
approx. 20 V
Continuous input current:
typ. 12 A / max. 15 A
Output variables
Rated output voltage:
DC 24 V, equivalent to input voltage
Voltage drop at 3 A per output:
typ. 150 mV
Output current setting range:
0.5...3 A, set with potentiometer
Switch-on delay:
for all outputs alike (setting values: 0 ms, 25 ms,
100 ms) or load dependent
Installation instructions
Mounting on a DIN EN 60715-35x7.5/15 standard rail. The device must be installed vertically with the input terminals (6, 11) at the bottom and the output terminals
(1, 7) at the top, in order to ensure adequate heat dissipation. A clearance of at least 50 mm must be left above and below the device.
To snap the device on to the rail, hang it with its lug (A) on the rail (C) and press until the spring (B) snaps into place. To remove it from the DIN rail, use a screwdriver
to loosen the spring (B) in the direction of the arrow and take off the device (see figure 1).
In Ex applications it must be ensured that installation is according to protection class IP 54.
After adjusting the device the cover of the potentiometer (5) and the switch (9) can be sealed (10).
To mark the device a label SKS/PC 20x7 can be inserted (8).

Function
IN +24V (6)
DC +24 V input voltage connection
(from "+" output of the power supply)
0V (11)
DC 0 V connection for supplying the internal electronic circuits
(from "–" output of the power supply)
OUT 1, 2, 3, 4 (1)
outputs for connecting the load circuits
11, 12, 14 (7)
floating common signaling contact (changeover contact)
RST (7)
remote reset
The 0 V connection (11) of the device merely serves to supply the internal electronic circuits.
The 0 V of the loads must be supplied directly to the power supply by means of separate lines.
The external circuitry of all terminals (including signaling and status contacts) must meet the safety requirements stipulated by VDE 0805 / EN 60950: SELV.
