Controller Hart device PI-485

Controller Hart device PI-485 is an intelligent microprocessor device that converts HART digital signals to serial data (RS-485 Protocol MODBUS Protocol). This allows directly connecting the HART devices to the systems based on MODBUS. Also functions of this device include:

• formation of signals of APS when the parameters exceed predefined thresholds (warning or emergency);
• collection and primary processing of signals from external sensors and devices;
• the formation of the output control signals;
• explosion protection type "intrinsically safe electrical circuit".

PI-485 has 4 galvanic isolated HART connector and 2 galvanic connector RS485 MODBU, making the controller safe. PI-485 works with all HART devices. Windows based software provides easy programming of the device.

Controller Hart device PI-485 provides intrinsically safe devices with HART interface class 0Ex ia IIC T5 (model PI-485 Ex).
