Notes
1 DI 0 I Digital input 0
2 DI 1 I Digital input 1
3 DI 2 I Digital input 2
4 DI 3 I Digital input 3
5 G1 GND Ground for DI0 – DI3 (electrically isolated relative to G)
6 G GND Ground
7 DI/DO 8 B Digital input/digital output 8
8 DI/DO 9 B Digital input/digital output 9 (can be used as a high-speed
input of the measuring input)
9 G GND Ground
10 DI/DO 10 B Digital input/digital output 10 (can be used as a high-
speed input of the measuring input)
11 DI/DO 11 B Digital input/digital output 11 (can be used as a high-
speed input of the measuring input)
12 G GND Ground
1)
DI: digital input; DI/DO: bidirectional digital input/output; G or GND: Electronics ground;
G1: Ground reference
2)
B = Bidirectional; I = Input; GND = Reference potential (ground)
Note
An open input is interpreted as "Low".
Terminal G1 must be connected for the digital inputs to function. The following alternatives
are available:
• Connect the carried digital input reference ground to M1.
• Create the bridge between terminal G and terminal G1.
This removes the electrical isolation for these digital inputs.
Using the digital inputs/outputs
Connecting sensors and actuators
Digital inputs and digital outputs can be used to connect various sensors and actuators to
the 12-pin X122 front connector.
The following types of digital inputs/outputs are used:
● Digital inputs
● Bidirectional digital inputs/outputs
Bidirectional digital inputs and outputs can be configured individually as digital inputs or
outputs.
