Components - Quanser AMPAQ-PWM User Manual

2 COMPONENTS

The components on the front and back panels of the AMPAQ-PWM are depicted in Figure 2.1. Each component
on the AMPAQ has an identification number that corresponds to a short description given in Table 2.1. The pin out
information for the analog sensor's mini-DIN connectors and the 16-pin digital I/O connector header are shown in
Figure 2.2.

AMPAQ-PWM User Manual
Description
The input command signal from the DAQ is a voltage
that controls the output current. The AMPAQ-PWM ad-
justs the output duty cycle to maintain the commanded
output current.
This connector provides a voltage proportional to the
actual output current. Scaling is 1 Volt = 2.1 Amps. The
AMPAQ-PWM must be connected to a load in order for
the Current Sense connector to output a voltage.
Indicates if the amplifier is powered up, as well as the
status of the amplifier. When the amplifier is powered
up but disabled, the LED turns red. When the amplifier
is powered up and enabled, the LED turns green.
This connector provides power to the load. The output
current is controlled by the Amplifier Command signal.
Indicates the calibration status of the connected device
(i.e. Shake Table II).
The AMPAQ-PWM requires an E-Stop (emergency
stop) button to be connected. If no E-Stop button is
connected, the AMPAQ-PWM is disabled by default.
Connector for an additional E-Stop to enable daisy-
chaining stop commands to multiple devices.
Carries the sensor I/O from the device including en-
coder signals, limit switch states, etc.

Used to send the analog sensor signals from the con-
nected device to an external DAQ
Used to properly power the analog sensors on the con-
nected device
Replaceable fuses to protect the amplifier
