Love LCU032


DATA SHEET:

The LCU032 Series temperature/process controls set a new standard in 1/32 DIN power, flexibility, and value. These controls offer family interchangeability with universal input and universal output. Ease of use is assured with the easy-to-read display 1/32 DIN temperature/process control.

The LCU032 offers universal input (13 thermocouple scales, 2 RTD types, voltage, and current), universal single set point with alarm, or heat / cool output. Standard features include Fuzzy Logic and Self-tune. Process protection is provided by open sensor protection and shorted sensor protection.

The LCU032 can be used as an indicator and the proportional current output programmed as a process retransmission output.  For the cost of a panel meter alone, you can have a panel meter with process retransmission, or a full blown PID process control

The LCU032 family of controls offers the greatest value with high levels of features, function, and quality available today.
