DC Input, Bipolar Output Field Configurable Isolator - AP4382

Shop Online

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.

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.

WARNING: Do not change switch settings with power applied. Severe damage will result!

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
