Digital inputs
Number of inputs (number of
channels)
16, unipolar with ground N,
Non-galvanically isolated from one another
(electrical isolation from the system bus and the
24 VDC supply voltage).
i
Ground N needs not to contact earth. If the
modules are redundantly wired, both
redundant channels must be connected in
phase to the same voltage.
Type of input
Current sinking logic, 48 VAC / 120 VAC, based
on type 1 in accordance with IEC 1-61131-2
Frequency
50/60 Hz sine, -6%...+ 4% (47...63 Hz)
Rated input voltage
0...48 VAC (nominal range 48 VAC)
0...120 VAC (nominal range 120 VAC)
Input voltage operating range
0...130 VAC (current limited to approx. 5 mA)
Switching point

Specifications for the Digital Inputs
Supply
External supply voltage
48 VAC or 120 VAC, 50/ 60 Hz, max. 130 VAC
Standby current
20 mA
Maximum current input
100 mA
Number of supplies
8 with 2 outputs each
Output voltage for supply
External supply voltage -3 VAC
Output current for supply
50 mA for each group, short-circuit-proof
Low voltage detection
The module monitors the supplies for low voltage (< 25
VAC).
If a fault occurs, the corresponding
Supply X OK
status
is set to FALSE.
Short-circuit of one supply
Low voltage detection active
The output current is pulsed < 250 mA while the supply
is short-circuited.
Assignment of the supply outputs
For supplying, the voltage output assigned to the input must be used.
