2.8 Digital inputs
Maximum lenght cable 10 m
Type Not optically isolated, voltage free contact
Power supply Internal

Multifunction analogue inputs (see note) B5, B6, B7, B8 B5, B6
Fast digital input ID1 ID1
Normal digital input ID2 ID2
Total 6 4
Tab. 2.g
Note:
Multifunction analogue inputs: these analogue inputs can be programmed via software as digital inputs instead of analogue
inputs. All the digital inputs refer to GND.
Specications of the fast digital input (ID1)
The fast digital input (ID1) can be configured via software in two distinct operating modes, as follows:
• first mode: normal or standard digital input
• second mode: fast digital input
When configured as a fast digital input, ID1 can measure a signal with a maximum frequency of 2 KHz, resolution +/- 1 Hz. This
is made possible by the BIOS, which provides the SW application with two variables that the count the number of times the
input signal crosses zero and the corresponding frequency in Hz.
Specications of the normal and fast digital input
The maximum current available to the digital input is 5 mA (consequently the rating of the external contact must be at least
5 mA).
