• If the following maximum load resistance R
L, max
is exceeded, the load resistance R
L
must be
reduced accordingly by parallel connection of R:
f ≤ 100 Hz: R
L, max
= 47 kΩ
f ≤ 1 kHz: R
L, max
= 10 kΩ
f ≤ 10 kHz: R
L, max
= 1 kΩ
• The minimum load resistance R
L, min
is calculated as follows:
R
L, min
= (U

• X designates the connection terminals A, B or D, depending on the version of the signal
converter.
INFORMATION!
•
For frequencies above 100 Hz, shielded cables are to be used in order to reduce radiation
from electrical interferences (EMC).
• Compact and field housing versions: Compact and field housing versions: Compact and field housing versions: Compact and field housing versions: Shield connected via the cable terminals in the terminal
compartment.
Wall-mounted version:
Wall-mounted version: Wall-mounted version: Wall-mounted version: Shield connected using 6.3 mm / 0.25" push-on connectors
(insulation to DIN 46245) in the terminal compartment.
• Any connection polarity.
