The PID330 is a sophisticated autotuning PID controller that supports thermocouple, RTD, or analog inputs, and has up to three outputs. It can be configured as 1 on/off or PID control and up to 2 alarm outputs, or as 2 on/off or PID controls (heat/cool) plus 1 alarm output. It has a large dual 4 digit LED display to show the set point and the process value.
The PID330 is a sophisticated autotuning PID controller housed in a compact 96 × 96 mm 1/4 DIN case. It features a dual 4‑digit LED display that shows both set point and process value, and can be configured for on/off or PID control with up to two alarm outputs. The unit accepts thermocouple, PT100, and analogue inputs and provides up to three configurable outputs, including relay, SSR, or analogue signals.
Technical specifications include a supply voltage of 24 Vac/de (or 85‑270 Vac/de, 50/60 Hz), input ranges for various thermocouple types (e.g., J ‑200 to 750 °C), optional 0‑4‑20 mA, 0‑10 V or 0‑5 V outputs, a 100 ms update rate, and CE/EN compliance. The controller weighs 270 g and fits a panel cut‑out of 92 × 92 mm.

It accepts thermocouples (J, K, T, R, S, C, E, B, N, U, W, Platinel), PT100 RTDs, and analogue signals ranging from -5 to 56 mV, 0‑10 V, or 0‑20 mA.
The controller can provide up to three outputs; each can be a 5 A @ 240 Vac relay or an 18 Vdc 20 mA SSR drive, with optional 0‑4‑20 mA, 0‑10 V or 0‑5 V analogue output.
It can be powered from a 24 Vac/de supply or from 85‑270 Vac/de at 50/60 Hz.
The accuracy is the greater of ±0.25 % of full scale or ±1 °C.
