Technical data
Description Data
External connection 4-pin plug connector
Number of inputs 3 (DI1, DI2, DI3)
Input voltage Low: U
DC
= 0…5V
High: U
DC
= 10…30V
Passive: external power supply required
Input current <11mA @ U
DC
= 24V
<5mA @ U
DC
= 12V
Signals DIGND (-) common for all inputs
Potential isolation yes, via optocoupler
Cable length max. 50 m, screened
Example:
Contact input
①
Supply unitU
DC
=24V0.5A
If the voltage at terminals (in this example: DI1-DIGND) is U
DC
=10V,
inputDI1 is active(true).
