Action Instruments G418 RTD Input Field Configurable Isolator

RTD Input Field Configurable Isolator

The Ultra SlimPak G418 is a DIN rail mount, RTD input signal conditioner with 1800VDC isolation between input, output and power. The field configurable input and output offers flexible, wide ranging capability for Platinum and Copper RTDs.

The input of the G418 Ultra SlimPak can be configured for any one of up to sixteen temperature ranges (see Tables 1 & 2). The output is linear to the RTD temperature input and can be set for either 0-5V, 0-10V, 0-1mA, 0-20mA or 4-20mA.

For an RTD and thermocouple input temperature transmitter with improved accuracy and stability, see Action I/Q model Q488. PC or DIP switch programmable. Wide ranging, precision zero and span pots allow 50% adjustably of offset and span turn-down within each of the sixteen switch selectable ranges. For example, the 0-500°F range could be offset and turned down to provide a 4-20mA signal representing 0-250°F (or 250-500°F).
