Cost-effective Zelio REG temperature controllers have the ability to interface with solid-state relays, electromechanical relays, programmable logic controllers (PLCs), variable speed drives and human-machine interface (HMI) displays. Temperature controllers are designed to automatically control the temperature at multiple points during the manufacturing process. Controllers come in three industry-standard formats: 24 x 48 mm (1/32-in. DIN); 48 x 48 mm (1/16-in. DIN); and 96 x 48 mm (1/8-in. DIN). The 24 x 48 mm model provides basic temperature control, while its 48 x 48 mm counterpart features an increased amount of control contacts and multiple alarms. The full-featured 96 x 48 mm model offers maximum performance and function.
