Connection of DIs
Example for 2 DIs:
Technical specifications
-
Number of digital inputs:
16
-
Contact type:
Dry self-powered contact: Normally open/ closed
(configurable positioning logic)
-
Maximum length of cable:
1,000 metres (AWG24 SYT+ cable type)
It is necessary to relay the digital inputs if the cable length is any higher
or if the cable crosses an environment with high interference.
-
Digital input filtering:
Any steady state digital input can be used for the counter acquisition;
the minimum duration of the steady state is 2 ms (max frequency = 250 Hz)
-
Isolation:
The DIs are isolated from the rest of the electronics; the isolation voltage
is 3000 V
DC
minimum. The DIs are not isolated from each other.
