The device HART controller PI-485 is an intelligent microprocessor device that converts digital HART signals to serial data (RS-485 MODBUS Protocol). This allows direct connection of HART devices to MODBUS-based systems.

The PI-485 has 4 isolated galvanic HART connectors and 2 galvanic connectors RS485 MODBU, which makes the controller safe. The PI-485 works with all HART devices. Windows-based software provides simple programming of the device.
The
Hart controller of PI-485 devices provides intrinsic safety of devices with HART interface in class 0Ex ia IIC T5 (model PI-485 Ex).
