7.4 Pulse output function module
The module is equipped with 2 pulse outputs, which can be freely pro-
grammed using the IZAR@SET software. The outputs are indicated as
"O1 - " and "O2 - " on the terminal strip and as Out1 and Out2 in the
display.
external supply:
Vcc = 3-30 VDC
output current ≤ 20 mA
with a residual voltage of
≤ 0.5 V
open collector (drain)
electrically insulated
Output 1: f ≤ 4Hz
Pulse duration:
125 ms ± 10 %
pulse pause:
≥ 125 ms – 10 %
Output 2: f ≤ 100 Hz
pulse duration/pulse
pause~1:1
The volume pulse weight-
ing can be freely pro-
grammed
standard: last digit in the
display
7.5 Combined function module (IN/OUT)
The combined module has 2 inputs and 1 output.
See chapter 7.3 for the specific
characteristics on the pulse
input.
The pulse output is specified
as pulse output 1 under point
7.4, not however galvanically
isolated.
