Low Cost ATR226 Temperature Controller from Ucontrol Australia

Ucontrol Pty Australia has introduced in the market the exclusive ATR226 model of temperature controller. This new model makes available in a single device multiple options related to sensor input and actuators command in addition to the extended power range 24..230 Vac/Vdc. With the existence of various selectable sensors and the SSR command, the user or retailer can easily reduce stock by rationalizing investment and device availability.

With regard to tuning, the user can either manually or automatically calculate regulation parameters. However, manual procedure gives the user more flexibility to decide when to update the PID algorithm parameters! Those people who don’t have any knowledge about PID regulation algorithm can also have a clear regulation for hassle-free automatic tuning procedure any time.

If there is installation malfunction at any time, the ATR226 temperature controller will instantly switch off regulation output and report the anomaly. For example, controller will report failure of a connected thermocouple visualizing e-05 (flashing) and Prb. (sensor).

To simplify the setting of parameters and the integration of the different components involved in the control system, ATR226 temperature controller has EASY-UP coding which allows setting sensors and/or commanding outputs in one single step. This controller from Ucontrol Pty Australia has 4 0,40 inch displays+ 4 0,30 inch displays with operating temperature 0-45 °C - Humidity 35..95 uR%. There is highly secured IP65 front panel sealing with gasket. The controller also comes with an IP20 box and terminals. ATR226 model is made of PC ABS UL94VO self-extinguishing material to ensure utmost safety. It is a lightweight model weighing just 130 grams!

One of the most affordable controllers from Ucontrol, ATR226 temperature controller has power supply 24..230 Vac/Vdc ±15% 50/60 Hz with consumption: 5.5 VA. In addition, the analogue input is configurable via software. It has automatic compensation of cold junction from 0°C to 50°C along with thermoresistance at PT100, PT500, PT1000, Ni100, PTC1K, NTC10K (? 3435K) respectively. This new controller has a tolerance level of +/-0.3% ±1 digit (su F.s.) with cold junction accuracy at 0.1 °C/°C. The ATR226 temperature controller has 2 relays configurable as command and/or alarm output and single SSR, 12V/30mA configurable as command output and/or alarm output.

Some of the software features include regulation algorithms which are ON-OFF with hysteresis, P, P.I., PID, P.D. with proportional time. The controller has proportional band 0..9999 °C o °F, integral time 0,0..999,9 sec. and derivative time 0,0..999,9 sec. omitting 0. As mentioned above, it is possible to regulate controller functions via manual or automatic tuning. It is also possible to protect command and alarm setpoints and activate functions via digital input, if required.

Although this new controller is designed to resist electromagnetic interferences in diverse industrial environments, nevertheless it is important to follow safety guidelines to avoid accidents.
