5.2.1 Power supply
(The figure shows the socket inside the device)
V+
+24 VDC ± 20 %
FE
Functional earth
0V
Reference potential
DI
Digital input 24 VDC
DO
Digital output 24 VDC
Conductor cross sections:
V+ / FE / 0V: AWG 18 (
≙
0.75 mm
2
)
Digital output:
type 3 according to IEC61131 (no self-diagnostic function)
0 signal = 0 V, 1 signal = 24 VDC, max. 30 mA.
Reverse voltage polarity protection. Automatic restart after fault state (e.g. after short circuit at
output).
Digital input
: type 3 according to IEC61131.
0 signal = 0…+5 VDC; 1 signal = +11…+30 VDC, max. 2.7 mA.
5.2.2 Earthing concept
The earthing concept essentially depends on the installation location and must be planned and
implemented by a specialist electrical engineer.
The following are provided on the device:
•
FE
connection in power supply connector as
EMC filter reference potential.
•
PE
earthing lug at lower end of
device housing.
Conductor cross sections:
•
PE
: ≥ AWG 16 (
≙
1.5 mm
2
), optimal: AWG 13 (
≙
2.5 mm
2
). The cable colour must be green-yellow.
•
FE
: AWG 18 (
≙
0.75 mm
2
). The cable colour must not be green-yellow.
ATTENTION
This connection is necessary in order to comply with
EMC
requirements.
Recommendation for use:
When possible, FE and PE should be connected to the central earthing rail via
separate
cable lines.
