SFP-1114（single channel）, SFP-2114（dual-channel）is used to isolate the transmitter and second instrument and power supply. It can offer communicating channel which in line of HART communication protocols for 1151SMART transmitter.

Features

The instrument can be equipped with the ordinary type or flameproof transmitter.

It can realize dual-channels data communications with 1151SMART transmitter. The distance is more than 500 meters.

Because of signal isolation techniques, it can effectively restrict common mode interference.

The circuit structure is simple.
