DC Input Field Confiurable Isolator - G408

Shop Online

The Ultra SlimPak G408 is a DIN rail mount, DC input signal conditioner with 1800VDC isolation between input, output and power. The field configurable input and output offers flexible, wide ranging capability for DC current and voltage signals.

The input of the G408 Ultra SlimPak can be configured for any one of 12 voltage ranges from 10mV to 100V or 6 current ranges from 1mA to 100mA (see table 1). The output is linear to the input and can be set for either 0-5V, 0-10V, 0-1mA, 0-20mA or 4-20mA (for models G408-0001) and -5 to +5V or -10 to +10V (for model G408- 1001).

Wide ranging, precision zero and span pots allow 50% adjustability of offset and span turn-down within each of the 18 switch selectable ranges. For example, the 0-2mA input range could be turned down to 0-1mA and provide a full scale output signal (e.g. 4-20mA), or turned down and offset to achieve a 1-2mA/4-20mA I/O combination.

The G408 also accepts bipolar inputs (e.g. 10V range set to bipolar = -10 to +10V) and offers selectable normal or reverse operation (e.g. 4-20mA/20-4mA). The ASIC based I/O channel is optically isolated to 1800VDC and is transformer isolated from the power supply.

Application

The Ultra SlimPak G408 field configurable isolator is useful in eliminating ground loops, converting signal levels, and providing signal drive. The field configurable, wide ranging capability ensures maximum flexibility for most DC to DC applications, minimizing spare part requirements.

Diagnostic LED

The G408 is equipped with a dual function LED signal monitor. The green, front mounted LED indicates both DC power and input signal status. Active DC power is indicated by an illuminated LED. If the input signal is more than 110% of the full scale range, the LED will flash at 8Hz. Below -10%, the flash rate is 4Hz.

A major advantage of the G408 is its wide ranging capability and ease of configuration. The G408 has 18 input range settings. Trim potentiometers allow 50% input zero and span adjustability within each of the 18 full scale input ranges.

Unless otherwise specified, the factory presets the Model G408-0001 and G408-1001 as follows:

G408-0001
Input Range: 4-20mA
Output Range: 4-20mA
   
G408-1001
Input Range: 4-20mA
Output Range: -10 to +10V

The DC power input accepts any source between 9 and 30V; typically a 12V or 24VDC source is used (see Accessories).

To minumize interference from electrical and magnetic fields, the use of shielded, twisted pair wires on the input and output is recommended.

Refer to Tables 1 through 4 for the proper switch settings. Use the switches on SW1 to select the input type (voltage or current) and also to select the desired input range and function setting. Use SW2 to select the desired type of output.

Calibration
  1. After configuring the dip switches, connect the input to a calibrated DC source. Connect the output to the actual device load (or a load approximately equivalent to the actual device load value) and apply power.
  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, as necessary, for best accuracy.
