Description

The field configurable AP4380 isolator offers wide ranging input
and output capability for scaling and transmitting analog DC
signals. The AP4380-2000 will accept input voltage spans from
10mV up to 100 volts, as well as input current spans from 1mA to
100mA. The AP4380-2001 will accept input voltages up to 200V,
as well as the same input current ranges.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,
compressed to 0-5V or set to 2.5 - 7.5V. The AP4380 offers four
(4) popular output ranges: 0-5V, 0-10V, 0-1mA and 4-20mA. The
4-20mA compliance is a powerful 20VDC. Model AP4380 can be
configured to accept bipolar input ranges and offers selectable
normal or reverse acting operation.

The AP4380 is a 3-port industrial isolator -- the output is optically
isolated from its input up to 1500 VDC. The ASIC*-based I/O
channel is independently transformer isolated from the selectable
120/240VAC power supply.

Application

The Action Pak AP4380 field configurable isolator is useful in
eliminating ground loops, converting signal levels and providing
signal drive and redundancy. The wide ranging capability of the
AP4380 provides quick universal spare part coverage.

Diagnostic LED

The AP4380 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% more than full scale range, the LED will flash
at 8Hz. Below 0%, the flash rate is 4Hz.

Options

U Urethane coating of internal circuitry for protection from

corrosive atmospheres.

Configuration

The factory presets the 4380-2000 input and output to 4-20mA, as
shown in Figure 1. The 4380-2001 is preset to 0/200V input and 4/
20mA output. 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.

 ASIC Technology for Enhanced Reliability

Refer to Figure 1 for configuration and program the I/O channel
as desired. Replace the cover before applying power.

Warning: Do not attempt to change any switch settings with
power applied. Severe damage will result!

Input

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

Note: A bipolar range selection will double any input range from
Table 1 (e.g, 10V span becomes a -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.

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 may result.

1. Using Table 2, configure Output Selector for one of the four (4)
standard outputs.

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.
