Table 5-3 X3: M12 socket, digital inputs/outputs and sensor supply, socket, A-coded
5-pole Terminal Designation
1)
Technical data M12
1 P24_SENSOR The DI/DO are protected against polarity reversal.
Digital input:
Voltage: -3 V ... +30 V DC
Current drain, typical: 10 mA at 24 V
Level (including ripple)
High level: 15 V … 30 V
Low level: -3 … +5 V
DI/DO are "rapid inputs"
2)
Input delay (typ.)
For "0" → "1": 10 μs
For "1" → "0": 1 ms
Digital output:
Voltage: 24 V DC
Max. load current per output: 100 mA (in total, maximum 200 mA)
Continuously short-circuit proof
Overload proof
Output delay
For "0" → "1": 150 μs/400 μs (typ./max.)
For "1" → "0": 75 μs/100 μs (typ./max.)
Note: Three configurations can be parameterized in the software
● 2 x DI → 100 mA sensor power supply
● 2 x DO → 2 x 100 mA for the DOs, it is not permissible that the sensor supply
is used
● 1 x DI/1 x DO → 100 mA sensor power supply and 100 mA for DO
M_EXT is the ground at the DI. It is functionally isolated. To increase the inter‐
ference resistance, we recommend connecting to (grounding).
2 DI/DO 0
3 M_EXT
4 DI/DO 1
5
1)
P24_SENSOR: 24 V external power supply
DI/DO: bidirectional digital input/output
M_EXT: Electronics ground
: Protective conductor
2)
The fast inputs can be used as a probe input.
Note
Cables for digital inputs
● Use shielded cables when using digital inputs/outputs (interface X3).
NOTICE
Damage to M12 threads through excessively high tightening torques
M12 connectors are not standardized. In some instances, it is not possible to completely
screw together connector and socket. An excessively high tightening torque can damage the
thread.
● You must observe the tightening torques specified by the manufacturer.
