2.5 A 6515 TWO RELAY DISTRIBUTION BOX (HIGH CURRENT) CONNECTION GUIDE
Fig 2.5a shows the layout of the front of the A 6515 Relay Distribution Box.
Fig 2.5a
1 24V DC input
Connects to a 24V DC Plugpack with a 2.1mm Jack (Please observe the polarity, centre positive).
2 24V DC Input
Connects to a 24V DC source via a euro block (Please observe the polarity).
3 RJ45 interface
This RJ45 port is for connection to other Redback® compatible devices.
4 Serial Input
This input takes either an RS232 or RS485 signal. This can be connected to one of the serial outputs of the
A 6505A or to a third party system. Follow standard RS232 or RS485 wiring when connecting these terminals.
5 RJ45 interface
This RJ45 port is for connection to the A 6530 or A 6540 series wall plate.
6 DIP Switches
1 ON: Accept serial codes through RS485 input.
2 ON: Accept serial codes through RS232 input.
3 ON: Accept serial codes from wall plate.
4: Not Used
NOTE: Only one of the DIP switches 1-3 can be on at any time.

1 Output 1
This output provides a voltage free output with a normally open and normally closed contact. This is congured via
the software as the relay 13 output. (The maximum current rating of these contacts is 16A.) The LED above the
terminals illuminate while the output is active.
2 Output 2
This output provides a voltage free output with a normally open and normally closed contact. This is congured via
the software as the relay 14 output. (The maximum current rating of these contacts is 16A.) The LED above the
terminals illuminate while the output is active.
