ATR 144


The ATR144 is a PID controller in the compact 32x74mm format that keeps the same flexibility of the entire ATR Blue Line range. The analogue input is programmable for a wide range of temperature probes as well as mA/Volt process signals (pressure, flow, leve, humudity...). Digital outputs are programmable as either ON/OFF control or PID regulation; multiple alarm modes (threshold, band, upper/low deviation..) are also selectable. RS485 communication serial and Modbus RTU/ Slave protocol are the network communication options. The extended range power supply 24....230V AC/DC with galvanic isolation from the mains extends its flexibility in the event of fluctuations in electricity grid  and also for stock management as one single code covers different applications.
