G428-0001 Input Field Configurable Isolator

The G428 is a DIN rail mount, thermocouple input signal conditioner with 1,800 Vdc isolation between input, output and power. 

The field configurable input and output offer flexible, wide ranging capability for J, K, T, R, S, E and B type thermocouples.

The G428 input can be configured for over 60 thermocouple temperature ranges. 

The output is linear to temperature and can be set for either 0 to 5 V, 0 to 10 V, 0 to 1 mA, 0 to 20 mA or 4-20 mA. 

Wide ranging, precision zero and span pots allow 50% adjustability of offset and span turn-down within each of the ranges.

For example, the 0° to 1,000° C range could be offset and turned down to provide a 4-20 mA signal representing 500° to 1,000° C. 

Similarly, adjustment can be referenced to the output range. 

The example above could be used to provide a 12 to 20 mA signal from a 750° to 1,000° C temperature input.
