EDR-5000
IM02602007E
DI-8 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;
Two non-grouped digital inputs; and
Six (6) digital inputs, grouped.
Auxiliary Voltage Supply
The auxiliary voltage inputs (wide-range power supply unit) are non-polarized. The device can be powered with
an AC or DC control voltage.
Digital Inputs
For each digital input group, the related voltage input range has to be
configured. Wrong switching thresholds can result in malfunctions/wrong
signal transfer times.
The digital inputs are provided with different switching thresholds (that are configurable) (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”.
When using DC supply, the negative potential has to be connected to the
common terminal (COM1, COM2, COM3 - please see the terminal marking).
