Specifications for the Measuring Inputs
Supply for inputs for measuring the frequency
Number of sources
3, short-circuit-proof
Output voltage
(depending on the sensors)
24 VDC, -15...+20 %
Max. output current for each supply
80 mA
OC/SC detection based on
configurable current values
0...80 mA ±10 %
Nominal short-circuit current,
per channel
(Supply to input)
5.45 mA at 24 V
Nominal short-circuit current,
per channel
(Supply to L-)
typ. 160 mA
The channel is switched off if an overflow occurs.
The affected channel is switched off and cyclically
switched on again
Supply monitoring
The module monitors the supplies for undervoltage.
If the
Supply used
parameter is activated, a supply
error results in a channel fault (
Channel OK
=
FALSE)
Assignment of the supply outputs
For supplying, the supply output assigned to the input must be used.
