The HI311 HART (Highway Addressable Remote Transducer) Serial (RS-232) Interface is designed to provide a full physical link between a HART" field instrument and an IBM compatible personal computer.

The interface draws power from the output signals of the RS-232 serial port without causing an overload condition on any pin.

The HI311 can be used with all HART" communication software packages which utilize RS-232, including Smar CONF401 HART" Communication Interface.

• Fully compatible with HART" products manufactured by SMAR and others;
• System powered: no need for external power supply;
• Tested isolation of 1500 Vdc between field instrument and EIA-RS232C adaptor pins;
• Plastic cable packaging for easy installation;
• Very low leakage current to the process network (Max 10 uA @35 Vdc);
• Standard DB9 serial port connect;
