DI-4 X - Power Supply and Digital Inputs
Make sure that the tightening torque is 5-7 In-lb [0.56-0.79 Nm].
This assembly group comprises:
A wide-range power supply unit; and
Four (4) digital inputs, grouped.
Auxiliary Voltage Supply
The auxiliary voltage inputs (wide-range power supply unit) are non-polarized. The device could be provided
with AC or DC voltage.
Digital Inputs
For each digital input group, the related voltage input range has to be
parameterized. Wrong switching thresholds can result in malfunctions/wrong
signal transfer times.
The digital inputs are provided with different switching thresholds (can be parameterized) (two AC and five DC input
ranges). The following switching levels can be defined:
24 Vdc;
48 Vdc
60 Vdc;
110/120 Vac/dc; and
230/240 Vac/dc.
If a voltage >80% of the set switching threshold is applied at the digital input, the state change is recognized (logically
“1”). If the voltage is below 40% of the set switching threshold, the device detects logically “0”.
The ground terminal has to be connected to the »- pole« when using DC
supply.
