Part Number ALS1
| Design considerations
The ALS1 is a low cost way to input light information into a PLC, process control meter, distributed control system (DCS), or other industrial control system. The AS1 can be mounted through any 1/2" hole and the two wires connected to an analog input card or other two wire 4-20 mA current loop circuit. The ALS1 is designed for low cost applications where standard accuracy is acceptable. Because the ALS1 has a PVC housing, care should be taken to insure that the operating environment does not get so hot that the PVC housing will soften. This may happen at temperatures around 180 to 190 degrees F. The ALS1 should not be used as the sole sensing element in critical equipment or safety applications.
