Note on wiring
1426
The wiring diagrams (
→ installation instructions of the devices, chapter "Wiring") describe the standard
device configurations. The wiring diagram helps allocate the input and output channels to the IEC
addresses and the device terminals.
The individual abbreviations have the following meaning:
A
Analogue input
BH
Binary high side input: minus switching for negative sensor signal
Binary high side output: plus switching for positive output signal
BL
Binary low side input: plus switching for positive sensor signal
Binary low side output: minus switching for negative output signal
CYL
Input period measurement
ENC
Input encoder signals
FRQ
Frequency input
H bridge
Output with H-bridge function
PWM
P
ulse-
w
idth
m
odulated signal
PWMi
PWM output with current measurement
IH
Pulse/counter input, high side: minus switching for negative sensor signal
IL
Pulse/counter input, low side: plus switching for positive sensor signal
R
Read back channel for one output
Allocation of the input/output channels:

Safety instructions about Reed relays
7348
For use of non-electronic switches please note the following:
Contacts of Reed relays may be clogged (reversibly) if connected to the device inputs without
series resistor.
►
Remedy:
Install a series resistor for the Reed relay:
Series resistor = max. input voltage / permissible current in the Reed relay
Example:
32 V / 500 mA = 64 Ohm
► The series resistor must not exceed 5 % of the input resistance RE of the device input
(
→ data
sheet). Otherwise, the signal will not be detected as TRUE.
Example:
RE = 3 000 Ohm
⇒
max. series resistor = 150 Ohm
