The 32DZ Series temperature/process controls set a new standard in 1/32 DIN power, flexibility, and value. Love Controls is proud to be the creator of the world s first dual zone control in the 1/32 DIN size. Ease of use is assured from the creators of the world s first dual display 1/32 DIN temperature /process control. The 32DZ offers a semi-universal input (10 thermocouple types in one of two groups, an RTD type, and voltage and current types). Each zone offers a single set point with mechanical relay, 5 VDC pulsed output, or AC SSR. One of the two outputs may be a proportional 4 to 20 mA output that may be assigned to either zone 1 or zone 2.Standard features include independent Fuzzy Logic, Selftune, and Peak/Valley indication for each zone.Process protection is provided by open sensor protection, shorted sensor protection, input rate of change protection, and loop break protection. Options for the 32DZ include RS-485 Serial Communication and low voltage operation. Designed and built in the USA, the 32DZ family of controls offers the highest levels of features, function, and quality available today.
