ATR171 is a PID controller with dual 4-digit displays that can be programmed for different applications in industrial environment.
One analog input is programmable for both temperature sensors and V/mA process signals. The optional second input is programmable only for temperature sensors for differential control applications.
Outputs are selectable as command, multiple alarm modes or analog retransmission.
Serial communication option is in RS485 with Modbus RTU/Slave protocol.
It is provided with extended range power supply from 24 to 230V AC/DC with galvanic isolation.
Digital input allows external activation of various functions, including Timer mode.
