描述
Ultra SlimPak G408是一款DIN导轨安装，直流输入信号调节器，在输入，输出和电源之间具有1800VDC隔离。现场可配置的输入和输出为直流电流和电压信号提供灵活，广泛的能力。
输入可以配置为从10mV到100V的12个电压范围或从1mA到100mA的6个电流范围中的任何一个(见表1)。输出与输入线性，可以设置为0- 5V, 0-10V, 0-1mA, 0- 20ma或4-20mA(型号G408-0001)和-5至+5V或-10至+10V(型号G408-1001)。
宽范围，精密零和跨度锅允许50%的可调偏移和跨度调低在每18个开关可选范围内。例如，0-2mA的输入范围可以调低至0-1mA并提供满量程输出信号(例如4-20mA)，或者调低并偏移以实现1-2mA/4-20mA的I/O组合。
G408还接受双极输入(例如10V范围设置为双极= -10至+10V)，并提供可选择的正常或反向操作(例如4-20mA/20-4mA)。基于ASIC的I/O通道光隔离到1800VDC，并且变压器与电源隔离
应用程序
G408在消除接地回路、转换信号电平和提供信号驱动方面非常有用。现场可配置，广泛的能力，确保最大的灵活性，为大多数直流到直流应用，最大限度地减少备件需求。
诊断了
G408配有双功能LED信号监视器。绿色，前置LED显示直流电源和输入信号状态。有源直流电源由发光的LED指示。
如果输入信号大于满量程的110%，LED将以8Hz闪烁。低于-10%时，闪速为4Hz。
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 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 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.
