5. Electrical data

5.1 Inputs

Digital inputs
Data:
Voltage category
Insulation voltage
Insulation test voltage
Input filter time
Digital inputs 5 to 7:
Output voltage
(open contact)
Output current
(closed contact)
Pulse counter input (DI8):
Max. frequency
Output voltage
(open contact)
Output current
(closed contact)
The digital inputs are activated by short-circuiting the
input concerned to 0 V, e.g. with a contact or a relay.
The pulse counter input, digital inputs and analog
inputs have the same minus potential. The inputs are
not isolated from each other.
