DC Input, Dual Channel Isolators

Provides Two Independent, Fully Isolated

DC Outputs in Proportion to Two DC Inputs

 High Density 2-Channel Package
 Eliminates Ground Loops with 1500V Isolation
 Six Configurable Output Ranges: 0-5V, 0-10V, 0-1mA,

4-20mA, -5 to 5V and -10 to 10V

Description

The field configurable AP4390 series dual channel isolators offer
wide ranging input and output capability for scaling and transmit­ting analog DC signals. The AP4390 series will accept input voltage
spans from 10mV up to 100 volts, as well as input current spans
from 1mA to 100mA. For a full scale output range, 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 AP4390 series offers 6 popular ouput ranges which are either
positive voltages and currents (e.g. 0-5V, 0-10V, 0-1mA and 4­20mA) or bipolar voltages (-5 to 5V and -10 to 10V). The model
number defines the ouput channel ranges as shown in Table 1.

The 4-20mA compliance is a powerful 20VDC per channel. All
models in the AP4390 series accept bipolar inputs and each I/O
channel offers selectable normal or reverse acting operation (e.g.
4-20mA or 20-4mA).

 Plug-in Installation
 Selectable 120/240VAC Input Power

Application

The Action Pak AP4390 series of field configurable isolators is
useful in eliminating ground loops, converting signal levels and
providing signal drive. The AP4390 series' dual channel design
conserves installation space in high density applications and offers
superior cost-benefit value over single channel isolators. The wide
ranging capability of the AP4390s provides universal spare part
coverage.

Diagnostic LED

The AP4390 series is equipped with dual function LED signal
monitors. 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.

Option

U Urethane coating of internal circuitry for protection

from corrosive atmospheres.

Each Action Pak in the AP4390 series is a dual, three-port,
industrial isolator -- both output channels are optically isolated
from their respective input channels up to 1500 VDC. The two
ASIC-based I/O channels are independently transformer isolated
from the selectable 120/240VAC power supply.

Configuration

Each channel of the AP4390 series can be independently set for a
wide variety of input and output ranges.

Factory Presets

The factory presets all inputs for 4-20mA. The preset for positive
based output channels is 4-20mA and -10 to 10VDC for bipolar
voltage output channels (as shown in Table 1 and Figures 1 and 2). 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 cards.

Refer to figures 1 & 2 for configuration and program the I/O
channels as desired.

Replace the cover before applying power.

Input

1. Position input jumper “W1” for Current (I) or Voltage (V) input.

3. Set position 6 of the Input Range Selector for Normal or Reverse

4. Using Table 2, 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 change switch settings with power applied.
Severe damage will result.

Output

1. For the AP4390 channels A and B, and the AP4391 channel B, use
Table 3 to configure the output selector switches for one of the
four(4) standard output ranges.

2. For the AP4392 channels A and B, and the AP4391 channel B,
position output jumper "W2" for -5 to 5V or -10 to 10V.

Power

1. Configure the AC jumpers for either 120 or 240 VAC operation.
See Figure 3.

Calibration

1. Connect the input to a calibrated DC voltage or current source
and apply power. Refer to PIN CONNECTIONS. Wait 1 hour for
thermal stability before monitoring the voltage/current output.

2. Set the calibrator to the desired minimum input and adjust the
Zero potentiometer for the desired minimum output.

3. Set the calibrator to the desired maximum input and adjust the
Span potentiometer for the desired maximum output.

4. Repeat steps 2 and 3 for best accuracy.
