Product Introduction
ACD-2KL is a automatic control instrument with sight display, alarm and control functions. Using relay contact output alarm, you can set the upper and lower limit alarm and back difference , then drives a relay output. Signal isolation design, eliminate interference. Its advantages of high control precision, fast response, stable operation, small size, convenient installation , makes it an ideal substitute for electrical contact instrument.
