Description of MTL4851 MTL4852 HART Multiplexers MTL4851 MTL4852 HART Connection System Arrived


The MTL4851 MTL4852 HART connection system is the system of choice for unrivalled flexibility. Based on 16 channel modularity the system can be easiliy expanded to cover up to 7936 HART devices on one network. The flexibility of the MTL4851/52 and its ability to communicate with any of the Instrument Management Software (IMS) packages on the market today allows us to offer the optimum solution for any application - both general purpose and Intrinsically Safe.

The HART multiplexer provides the brains of the system and consists of a combination of two modules, the MTL4851 - HART communications module and MTL4852 - HART interface module. They provide the HART data interface between smart devices in the field and HART instrument management software running on a PC. The modules, which mount on to a range of HART backplanes, connect to the field devices via either HART connection units or IS backplanes depending on the application.

Features of MTL4851 MTL4852 HART Multiplexers MTL4851 MTL4852 HART Connection System Arrived

• 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 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.

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.

For the optimum solution, choose from a range of general purpose and IS termination boards. For maximum flexibility the HMM64 HART backplane locates an MTL4851 master communications module and up to three MTL4852 secondary interface modules, with each module connecting to 16 field devices. General purpose HART connection units and IS backplanes are available fitted with an cable interface connection to the HMM64. This system can be extended with further HMS64 HART backplanes linked to the master, each carrying up to four MTL4852 secondary interface modules.

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.

The HCU16 HART units connect to 16 general purpose field instruments while maintaining channel to channel isolation. Resistor conditioning options are compatible with all types of I/O cards. It allows pass-through connections for transmitter power supply, input signal and common.

The HCU16AO unit includes HART filters for use with I/O cards that are incompatible with HART communication signals.

Customised backplanes and connection units are available to provide direct connection from DCS I/O cables, replacing the standard termination boards.

See also the MTL4850 datasheet for alternative HART solutions using a 32 channel multiplexer module ideally suited for use in conjunction with emergency shutdown and safety systems.
