Interface Information / Wiring Diagrams
To make the connections for the InterBus, the supply voltage and the digital input, connect
the pre-assembled cable to the processor. For additional wiring information, see the
following
.
Connect the read/write heads to the terminals for Head 1 and Head 2.
The BIS C-6021...ST8 processor is intended for use on the installation remote bus, which
provides the supply voltage over the bus. The BIS C-6021...ST9 processor is intended for use
on the remote bus, whereby the supply voltage for the processor is brought in through X1.
Connect the incoming I
NTER
B
US
cable to the I
NTER
B
US
input X3. Connect the outgoing
I
NTER
B
US
cable to the I
NTER
B
US
output X2.
If this remote bus station is the last one on the bus, the I
NTER
B
US
output X2 must be closed
off with a threaded cap to maintain the enclosure rating.
Please note the load capacity of the I
NTER
B
US
cable and verify during operation that the supply
voltage is maintained at the processor (see Technical Data for specifications).
