Product Highlights

The PUR44D PID Controller is a dual-function device, acting as a simple two-step controller (ON-OFF or hysteresis controller) and an advanced PID controller. It supports two control loops for heating and cooling and is equipped with auto-tuning and Fuzzy-Logic algorithms. The controller features a dual-row display, presenting measured values in the first row and programmed values in the second. It offers a choice of output options, including built-in REL, OC (SSR), or analogue output, such as active current, passive isolated current, or active voltage output, catering to customer preferences. The PUR44D controller is compatible with a universal input, accommodating various signal types like 0/4-20 mA, 0-10V, 0-150 mV, Pt 100/500/1000, or TC (K, S, J, T, N, R, B, E). It compensates for the cold junction of thermocouple sensors automatically and provides linearised characteristics for RTD and TC inputs. The controller can be easily configured using the local keyboard or the free S-Config software through the RS-485 communication port.
