Weidmuller G408 Ultra SlimPak - Manual (Page 3)

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 as follows:
Input Range: 4-20mA Output Range: 4-20mA
The DC power input accepts any source between 9 and 30V; typically a 12V or 24Vdc source is used
To minimize interference from electrical and magnetic fields, the use of shielded, twisted pair wires on the
input and output is recommended.
Do not attempt to change any switch settings with power applied. Severe damage will result!
Refer to Tables 1 through 3 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.
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.
Note: To maximize thermal stability, final calibration should be performed in the operating installation, allowing
approximately 1 to 2 hours for warm up and thermal equilibrium of the system.
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.
