Modbus PID controller ATR171

serial4-digitpanel-mount

PID controller 72x72mm, with dual 4-digits display for high visibility in the industrial environment, distinguished by high configurability. Two inputs can be programmed for a wide range of sensors. The outputs can be set as control, alarm, or analogue retransmission. The serial communication option is RS485 with Modbus RTU/Slave protocol. Power supply range from 24 to 230V AC/DC with galvanic isolation from network and galvanic isolation between inputs and analogue output. The heating-cooling PID control algorithm can also be used for cascade control through remote setpoint by analogue input. The digital input allows external activation of various functions, including the Timer for delayed start or timed control.
