3.7 SERIAL and IR CONTROL with FIFTEEN LOW POWER and TWO HIGH CURRENT RELAYS
This configuration expands the standard setup to provide serial and IR control with 15 low power output relays and two high
current output relays.
The A 6530 or A 6540 series wallplate is connected to the A 6505A Serial Hub via a CAT5e/6 cable. 24V DC power is con-
nected to the A 6505A by a plugpack with a 2.1mm jack or through the euro block terminals. The A 6505A in turn powers
the A 6530 or A 6540 series wallplate through the Cat5e/6 cable and powers the A 6510 and A 6515 by running a cable
from the 24DC In terminals of the A 6505A to the 24V In terminals of the A 6510 and A 6515.
The A 6505A Serial Hub can then be connected to up to two RS232 or RS485 controlled devices. IR control of multiple
devices is available through the IR repeater output and a total of seventeen relay outputs enable control of devices with
a closing contact. The relay contacts on the A 6505A are rated at 2A maximum and a set of normally open and normally
closed contacts are available for each relay. The relay contacts on the A 6510 are rated at 1A maximum with normally open
contacts only. The relay contacts on the A 6515 are rated at 16A maximum with a set of normally open and normally closed
contacts for each relay.
