AP4382
DC Input, Bipolar Output,
Field Configurable Isolator
Provides a Fully Isolated DC Output
in Proportion to DC Input
Eliminates Ground Loops
Field Configurable Input Ranges: 10mV to 100V,
1mA to 100mA
Two Field Configurable Output Ranges: -5 to 5V
and -10 to 10V
Description
The field configurable AP4382 isolator offers wide ranging input
and output capability for scaling and transmitting analog DC
signals. The AP4382 will accept input voltage spans from 10mV up
to 100 volts, as well as input current spans from 1mA to 100mA.
The input zero and span potentiometers enable 50% input zero
and span adjustability. For example, the 0-10V input range can be
elevated to 5-10V, or compressed to 0-5V. The AP4382 offers two
(2) bipolar output ranges: -5 to 5V and -10 to 10V.
Model AP4382 also accepts bipolar inputs and offers selectable
normal or reverse acting operation
The AP4382 is an industrial isolator - the output is optically isolated
from its input up to 1500 VDC. The ASIC-based I/O channel is
independently transformer isloated from the selectable 120/
240VAC power supply.
Application
The Action Pak AP4382 field configurable isolator is useful in
eliminating ground loops, converting signal levels and providing
signal drive. The wide ranging capability of the AP4382 provides
quick universal spare part coverage.
Diagnostic LED
The AP4382 is equipped with a dual function LED signal monitor.
The green, top-mounted LED indicates line power and input signal
status. Active line power is indicated by an illuminated LED. If the
input signal is 10% above the full scale range, the LED will flash at
8Hz. Below 0%, the flash rate is 4Hz.

Note: A bipolar range selection will double any input range from
Table 1 (e.g, 10V span = -10 to 10V bipolar span)
3. Set position 6 of the Input Range Selector for Normal or Reverse
operation. Reverse acting produces a decreasing output with an
increasing input.

Configuration
The factory preset input is 4-20mA and the output is -10 to 10V,
as shown in Figure 1. The supply power is configured for 120 VAC
operation. For other I/O ranges, remove the four base screws and
case to access the I/O card.
Refer to Figure 1 for configuration and program the I/O channel
as desired. Replace the cover before applying power.
4. Using Table 1, configure positions 1 through 4 of the Input Range
Selector for the desired maximum input. Round the desired maximum input value to the next highest range (e.g., 0-70V = 100V range).

Warning: Do not configure the output ranges with the power on.
Damage to unit will result.
Output
1. Position output jumper "W2" for -5 to 5V or -10 to 10 V

Power
1. Configure the AC jumpers for either 120 or 240 VAC operation.
See Figure 2.
Calibration
1. Connect the input to a calibrated DC voltage or current source
and apply power. Wait 1 hour for thermal stability before
monitoring the voltage/current output. Refer to PIN CONNECTIONS.
2. Set the calibrator to the desired minimum input and adjust the
Zero, 20-turn, potentiometer for desired minimum output.
3. Set the calibrator to the desired maximum input and adjust the
Span, 20-turn, potentiometer for desired maximum output.
4. Repeat steps 2 and 3 for best accuracy.
