Peaktronics AMI-103 Quick Start Manual

PEAKTRONICS
The Peaktronics AMI-103 AC Motor Interface is
used to interface common electrical control signals to AC
actuators. The unit provides the motor drive circuits, pro-
tection circuits, and isolation between the control inputs
and motor outputs. A wide range of external control sig-
nals can be used to Open and Close the actuator. The unit
accepts commonly used 120VAC signals from PLC mod-
ules, relay circuits, triac outputs, or solid state relay cir-
cuits. Alternatively, signals from a number of electronic
sources, including TTL, CMOS, analog drivers, open col-
lector outputs, and low voltage AC outputs, can be used.
The unit has a built-in repeat cycle timer that can
be independently enabled or disabled for Open and Close.
The timer can be adjusted for 0.1 to 2 seconds "ON" time
and for 0.5 to 10 seconds "OFF" time. Since some AC
motors cannot be switched instantly from open to close
operation, the unit provides an adjustable input delay fea-
ture.
The unit can be configured for 2-wire or 3-wire
control. In 2-wire control, the control signal is applied to
the Open input to drive the actuator open. When the con-
trol signal is removed, or driven to 0V, the actuator will
automatically close. In 3-wire control, both control sig-
nals (Open and Close) are used to drive the actuator to-
ward open or closed as desired. When both signals are
removed, or driven to 0V, the actuator remains at its last
position.
The unit also features a red LED indicator (for the
open output), a green LED indicator (for the closed out-
put), an on-board fuse, two removable screw terminal
strips (for easy servicing), and on-board switches to man-
ually open or close the actuator. An auxiliary +24VDC
power output (that is isolated from the motor and control
signals) can be used to power a 4-20mA or 0-5 / 10V
• On/Off Controller for 24VAC, 117VAC, or 234VAC actuators.
• Accepts wide range of AC or DC control signals.
• Accepts open collector control signal for easy interface to common bus modules.
• On-board switches for manual control.
• Configurable for 2-wire control (Open input only) or 3wire control (Open/Close inputs).
• On-board +24VDC output to power feedback transmitter and/or open collector inputs.
• Built-in repeat cycle timer for open, close, or both.
• Control inputs, motor outputs, and +24VDC output are electrically isolated from one
another.
transmitter. A transmitter (such as the Peaktronics XMA-
105 or XMA-106) can be used to provide a position feed-
back signal from a feedback potentiometer (such as the
Peaktronics POT-102).
The unit comes with standoff mounts and includes
an insulating sheet that allows the unit to be mounted di-
rectly to the actuator housing or bracket. The unit is rated
for 5A at 60°C when properly mounted to a metal bracket
or metal actuator housing. The AMI-103 is rated for
117VAC ±10%, the AMI-103A is rated for 234VAC
±10%, and the AMI-103B is rated for 24VAC ±10%.
