Series D16A Temperature Controller

Latest microprocessor based technology affords full programmability with complete array of features in compact ultralow cost unit. D16A Series Temperature/Process Controller features universal input, Self-Tune® PID, Fuzzy Logic, and dual four-digit LED displays for process and set point value. Selectable inputs can be thermocouple, RTD, current or voltage. Available outputs are solid-state relay, relay, pulsed voltage, or proportional current. Programmable alarm (optional) can be reset automatically or manually. Front panel is waterproof and corrosion resistant (UL type 4-X), making it ideal for sanitary applications. Replace electronics without wiring changes (via removable front panel). Self diagnostics, nonvolatile memory and selectable control modes are all designed for greater productivity. Four security levels are password protected. On-off, P, PI or PID manual tune control functions can be selected or the controller will Self-Tune® automatically for best PIF control.

The D16A2 offers the best value in Standard Features in a Process and Temperature control. In addition to the features listed above, the D16A2 offers Peak/Valley indication, Percent output indication, Digital Input Filter, and a host of others.

The D16A3 add to the list with additional features including 16 segment Ramp/Soak and Auto/Manual station with front panel activation. Consult factory for pricing of D16A3 models.
