Description

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 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 0­5V, 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.

 Flexible Power Supply Accepts 9 to 30 VDC
 ASIC Technology
 RoHS Compliant

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 G408­0001 and G408-1001 as follows:

G408-0001

Input Range:

Output Range:

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).

4-20mA
4-20mA

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 G408 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.

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

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

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 output type.

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 device load) 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.

Note: All Ultra SlimPak modules are designed to operate in ambient
temperatures from 0 to 55°C when mounted on a horizontal DIN rail. If
five or more modules are mounted on a vertical rail, circulating air or
model HS01 Heat Sink is recommended. Refer to HS01 Technical
Bulletin (#721-0549-00) or contact the factory for assistance.
