ATR243 integrates in a single devices all available options for sensor input and control outputs, beside the new extended power supply 24...265Vac/dc. The input is configurable for up to 18 different sensor options. Beside standard relay, SSR and 4...20mA signal, the output includes now also the 0..10V signal for command or rescalable retransmission. Among new software features, it is worth to mention the possibility to launch Tuning by digital input, the optional manual reset of alarm condition ("Limit controller"), latch-on function for sensors calibration (including load cells). High configurablity will be particularly appreciated by distributors, to reduce stock needs. Optional features are the serial communication RS485, protocol ModbusRTU, and load monitoring function with amperometric transformer TA. Memory Card is now provided with internal battery, therefore it can be used without connecting the controller to power supply. Last but least, the ATR243 comes in a new enclosure with silicon rubber keys, aiming to gradually extend the layout and family feeling introduced with ATR121. UL-CSA approval in progress.
