Design considerations

The ACCT1 is a low cost way to input AC current information into a PLC, process control meter, distributed control system (DCS), or other industrial control system. The ACCT1 can be mounted through any flat surface and the two wires connected to an analog input card or other two wire 4-20 mA current loop circuit.

The ACCT1 is designed for low cost applications where standard accuracy is acceptable.

Because the ACCT1 has a ABS housing,  care should be taken to insure that the operating environment does not get so hot that the ABS housing will soften. This may happen at temperatures around 180 to 190 degrees F.

The ACCT1 should not be used as the sole sensing element in critical equipment or safety applications.
