Analog Output
Fig. 14: RO-3AI - Pin Assignment
For details on the Analog Output please refer to the Technical Data, ╚═▷ “Technical Data
EMR-3MP0”.
Relay Outputs
The Relay Outputs are potential-free contacts.
The assignment of the Relay Outputs is described in ╚═▷ “Relay Output Con󰊎guration”.
Check the “EMR-3MP0 Reference Manual” (separate document) for a list of signals that
can be assigned.
CAUTION!
Please carefully consider the current carrying capacity of the Relay Outputs. Please refer
to the Technical Data (╚═▷ “Technical Data EMR-3MP0”).
Selfsupervision Contact
The Selfsupervision Contact contact (“SC”) cannot be con󰊎gured. It is a changeover (Form
“C”) contact that picks up when the device is free from internal faults. While the device is
booting up, the “SC” relay remains dropped-o󰊍 (unenergized). As soon as the system is
properly started (and protection is active), it picks up and the assigned LED is activated
accordingly (please refer to the Self Supervision chapter, ╚═▷ “Self-Supervision”).
