Power Supply
For easy use in industrial environments, the ADAM mod-
ules are designed to accept industry standard +24 V
DC
unregulated power. Operation is guaranteed when using
any power supply between +10 and +30 V
DC
. Power rip-
ples must be limited to 5 V peak to peak while the voltage
in all cases must be maintained between +10 and +30
V
DC
. All power supply specifications are referenced at
module connector.
The power cables should be selected according to the
number of modules connected and the length of the
power lines. When using a network with long cables, we
advise the use of thicker wire to limit the line voltage drop.
In addition to serious voltage drops, long voltage lines can
also cause interference with communication wires.
We advise that the following standard colors (as
indicated on the modules) be used for power lines:
+Vs (R) Red
GND (B) Black
Communication Wiring
We recommend that shielded-twisted-pair cables that
comply with the EIA RS-485 standard be used with the
ADAM network to reduce interference. Only one set of
twisted-pair cables is required to transmit both data and
RTS signals. We advise that the following standard colors
(as indicated on the modules) be used for the communica-
tion lines:
DATA + (Y) Yellow
DATA - (G) Green
Basic configuration hook-up.
Before placing a module in an existing network, the mod-
ule should be properly configured. The two following dia-
grams show typical layouts for both modules.
