Technical data
Description
Data
External connection
4-pin plug connector
Number of inputs
3 (DI1, DI2, DI3)
Input voltage
Low: U
DC
= 0…5 V
High: U
DC
= 10…30 V
Passive: external power supply required
Input current
<11 mA @ U
DC
= 24 V
<5 mA @ U
DC
= 12 V
Signals
DIGND (-) common for all inputs
Potential isolation
yes, via optocoupler
Cable length
max. 50 m, screened
Example:
Contact input
①
Supply unit U
DC
= 24 V 0.5 A
If the voltage at terminals (in this example: DI1-DIGND) is U
DC
= 10 V,
input DI1 is active (true).
