MTL4851 and MTL4852 HART® connection systems

The MTL4851 and MTL4852 HART connection system provides a simple interface between smart devices in the field, control systems and HART instrument management software run on a pc.

• Designed to mount directly to a range of general purpose HART® connection units and IS backplanes

• Provides a simple interface to smart devices in the field

• Connect up to 7936 HART® devices on a single RS485 network

• LED indication for fault diagnosis

• Auto baud rate detection

• Connectivity to HART® configuration and Instrument Management software (IMS)

The system is based on 16-channel modularity to provide a compact, easily configurable and expandable system. Using a standard RS485 serial link up to 7936 HART devices can be connected on a single network.

The MTL4851 and MTL4852 modules can also be located on HTPSC16x termination boards for general purpose applications. HART loops are simply wired through these HART Termination Panels and may be grounded or floating circuits. The HTP boards offer a compact and costeffective solution for general applications. CPH-SC16x backplanes are ideal for signal loops requiring intrinsic safety (IS) protection, combining multiplexer and IS isolator mounting. This offers considerable simplification in wiring when compared to DIN-rail based solutions.
