Replacing
AMC-102x with AMC-103x (refer to Datasheets for complete
details)
MECHANICAL
The
AMC-103x has the same package and mounting dimensions, allowing
it to directly replace an AMC-102x.
ELECTRICAL
The
AMC-103x has a 13-pin screw terminal strip vs. the AMC-102x
12 pin screw terminal strip. When replacing an AMC-102x
with an AMC-103x, care should be taken in properly wiring
the unit - the terminal numbers do not match between
the two units.
The
AMC-103x terminal strip can accept larger wire sizes (up
to 12 AWG) than the AMC-102x terminal strip (wire sizes
up to 14 AWG).
The
AMC-103x has a field replaceable fuse (see Datasheet for
replacement type), while the AMC-102x does not have this
feature.
The
AMC-103x powers the feedback potentiometer with +5V instead
of +2.5V on the AMC-102x. This does not result in any functional
difference and both units can accept potentiometer values
from 1K ohms to 10K ohms.
The
(+)4-20mA command signal connected to an AMC-102x should
be connect to the (+)4-20mA / 1-5V IN terminal on an AMC-103x,
and the (-)4-20mA connection on an AMC-102x should be connected
to the SIGNAL GND terminal on an AMC-103x. Note, that the
AMC-103x must be configured for a 4-20mA command signal
by setting the on-board jumper plugs (see AMC-103 Datasheet
for details on configuring the unit).
FUNCTIONAL
As a
direct replacement of the AMC-102x, the AMC-103x functions
identically.
The
AMC-103x can also be configured for a 1-5V, 0-5V, or 0-10V
command signal by setting the on-board jumper plugs (see
Datasheet for details), whereas the AMC-102x can only accept
a 4-20mA command signal.
The
AMC-103x provides an auxiliary +12V power output used for
powering a Peaktronics transmitter - this feature is not
available with the AMC-102x. Transmitters are available
for providing position feedback signals (either 4-20mA or
0-5/10V), manual control command signals, or for converting
135 ohm slide wire controls to 4-20mA command signals. Since
Peaktronics mounting kits already have the provision for
mounting a transmitter, an AMC-102x installation can be
easily upgraded with an AMC-103x and a transmitter (refer
to the specific mounting kit for details).
For
applications using 10 second actuators, or slower, the AMC-103x
provides higher resolution than the AMC-102x.
