PID controller 48×96 mm (1/8 DIN)
Up to 5 relays, 2 analog inputs, 12 segment programmer
The Pixsys ATR444 is a 48×96 mm (1/8 DIN) PID controller designed for applications that require more information and outputs. Its large alphanumeric display displays the measurement, scrolling status messages, and online help, and its 8-key keyboard features programmable function keys.
According to the version, the ATR444 has one or two 16-bit analog inputs, programmable for thermocouples, thermistors, 0…10 V, 0/4…20 mA, 0…60 mV or potentiometer signals. The two-input versions perform mathematical operations between the measurements.
The 5 A relay outputs, the two SSR outputs and the 4...20 mA or 0...10 V analog outputs are used for regulation, alarms or the transmission of the measurement and setpoint values.
In addition to PID regulation, the ATR444 runs a cycle of up to 12 segments, with wait functions at the end of segments and resume functions. A simple solution for ramp-up and temperature maintenance.
Configuration is done via NFC with the MyPixsys app, via micro USB with MyPixsysLab or via Memory Card. The -T versions add an isolated RS485 port in Modbus RTU, compatible with the Pixsys IIoT modem CNV580 for remote monitoring.
DYNATIME SA distributes the ATR444 in Switzerland and helps you select the version suitable for the number of outputs and inputs in your installation. Discover our complete range temperature control or request a quote.
