These self-tuning controllers offer many options to fit your application. Choose from 1/32-, 1/16-, 1/8- (vertical), and 1/4-DIN sizes. Models are available with SPST alarm relay. A set point modifier creates a temporary set point that allows the controller to recover quickly. Models with fuzzy logic are available in 1/32-, 1/16-, and 1/4-DIN sizes. Controllers feature a variety of output configurations: SPST relay, SPDT relay, SSR, pulse output, or 4 to 20 mA output. Quiet and reliable 4 to 20 mA output includes a regulated, isolated 24 V loop power supply. Models with output relays require snubber 89800-99 when connecting to an inductive load; order snubber below. Order probes separately. Call our Application Specialists for more information on these products or to special order a controller with other options.
