Eaton EDR-5000 Installation, Operation And Maintenance Manual page 60

The digital inputs are provided with different switching thresholds (can be parameterized) (two AC and five DC input
ranges). For each group the following switching thresholds can be defined:
24V DC
48V DC / 60V DC
110 V AC/DC
230 V AC/DC
If a voltage >80% of the set switching threshold is applied at the digital input, the state change is recognized (physically
"1"). If the voltage is below 40% of the set switching threshold, the device detects physically "0".
The ground terminal has to be connected to the »-pole« when using DC
supply.
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.
Via the »assignment list« the states of the digital inputs are assigned to the
module inputs (e.g. I[1]).
