Installation and Connection
Slot X2: Relay Output Card
Rear side of the device (Slots)
The type of card in this slot is dependent on the ordered device type. The different variants have a different
scope of functions.
Available assembly groups in this slot:
•
(OR-5 X2):
Assembly Group with 5 Changeover (CO), Supervision Contact (SC)
•
(OR-3AI X2):
Assembly Group with 2 Normally Open (Form A), 1 Changeover (Form C), SC,
Analog Output IRIG-B
The available combinations can be gathered from the ordering code.
Binary Output Relays and System Contact
The number of the binary output relay contacts is related to the type of the device or type code. The binary
output relays are potential-free change-over contacts. In chapter [Assignment/binary outputs] the assignment of
the binary output relays is specified. The changeable signals are listed in the »assignment list« which can be
found in the appendix.
Make sure that the tightening torque is 0.56-0.79 Nm [5-7 In-lb].
Please duly consider the current carrying capacity of the binary output
relays. Please refer to the Technical Data.
The
System-OK contact (SC relay)
cannot be configured. The system contact is a changeover contact that
picks up when the device is free from internal faults. While the device is booting up, the
System OK relay (SC)
remains dropped-off (unenergized). As soon as the system is properly started (and protection is active), the
System Contact picks up and the assigned LED is activated accordingly (please refer to the Self Supervision
chapter).
