The DI8 module is an add-on module with eight (8) galvanically isolated digital inputs. This module can
be ordered directly to be installed into the device in the factory, or it can be upgraded in the field after
the device's original installation when required. The properties of the inputs in this module are the same
as those of the inputs in the main processor module. The current consumption of the digital inputs is 2
mA when activated, while the range of the operating voltage is from 0…265 VAC/DC. The activation
and release thresholds are set in the software and the resolution is 1 V. All digital inputs are scannced
in 5 ms program cycles, and their pick-up and release delays as well as their NO/NC selection can be
set with software.
For the naming convention of the digital inputs provided by this module please refer to the chapter titled
"Construction and installation".
For technical details please refer to the chapter titled "Digital input module" in the "Technical data"
section of this document.

Description
DIx
Polarity
0: NO (Normally
open)
1: NC (Normally
closed)
-
0: NO
Selects whether the status of the digital input is 1 or 0 when the input is
energized.
DIx
Activation
threshold
16.0…200.0 V
0.1 V
88 V
Defines the activation threshold for the digital input.
When "NO" is the selected polarity, the measured voltage exceeding this
setting activates the input. When "NC" is the selected polarity,
the measured voltage exceeding this setting deactivates the input.
DIx
Release
threshold
10.0…200.0 V
0.1 V
60V
Defines the release threshold for the digital input.
When "NO" is the selected polarity, the measured voltage below this
setting deactivates the input. When "NC" is the selected polarity,
the measured voltage below this setting activates the input.

0.000 s
Defines the delay when the status changes from 0 to 1.
DIx Drop-
off time
0.000…1800.000

0.001
s
0.000 s
Defines the delay when the status changes from 1 to 0.

0:
Disabled
Selects whether or not a 30-ms deactivation delay is added to take the
alternating current into account. The "DIx Release threshold" parameter is
hidden and forced to 10 % of the set "DIx Activation threshold" parameter.
