Product Description

MTL4852 HART Secondary Interface Module Overview

The MTL4852 HART connection system provides a reliable interface between smart field devices, control systems, and HART instrument management software running on a PC.

System Architecture & Configuration

Based on 16-channel modularity, this system offers compact, easily configurable and expandable connectivity. Using a standard RS485 serial link, up to 7936 HART devices can be connected on a single network.

Flexible System Integration

HMM64 HART backplane accommodates one MTL4851 master communications module and up to three MTL4852 secondary interface modules
Each MTL4852 module connects to 16 field devices
System can be extended with additional HMS64 HART backplanes linked to the master
Choose from general purpose and IS termination boards for optimal solutions

Application Solutions

HTP-SC16x termination boards for general purpose applications
CPH-SC16x backplanes for signal loops requiring intrinsic safety (IS) protection
Simplified wiring compared to DIN-rail based solutions
