Product Description

The MTL4851 is a HART communication module manufactured by GE as part of the MTL4851/52 HART connection system, which provides an interface between intelligent field devices and HART meter management software running on a PC. The following is the detailed description and parameters of the product:

Model: MTL4851
Brand: GE (General Electric)
System name: MTL HART Connection System
Module type: Master Communications Module
Number of channels: 16 HART channels (channels 1 to 16)
HART device type: Supports HART revisions 5 through 7
Host system interface: RS485 2-line multi-drop (up to 31 MTL4851 modules can be connected to a host)
RS485 baud rate: 38400, 19200, 9600, 1200 baud rate – automatic detection
Power requirements: 19V to 35V DC, working current 42mA (24V ±10% condition)
Ambient temperature range: Operation: -40°C to +60°C; Non-operating: -40°C to +85°C
Relative humidity: 5% to 95% – non-condensing
Dimensions: See drawing (specific dimensions not given in text)
Weight: 95g (MTL4851 module)
Certification: ATEX and IECEx (for Zone 2 environments)
LED indicator: including power (green), fault (red), host (yellow), HART (yellow) indicator, used for status display and fault diagnosis
Automatic baud rate detection: Automatically detects the communication speed
Connectivity: Up to 7936 HART devices can be connected on a single RS485 network
Software connectivity: Supports connectivity to a variety of FDT-based software packages, including AMS Device Manager, Cornerstone ASTEC, FieldCare, PACTware, etc., via communication Device Type Manager (DTM)
The MTL4851 module is designed to be mounted on a HART backplane, such as HMM64 or HMS64, and can be used with up to three MTL4852 secondary interface modules, each connected to 16 field devices. In addition, the MTL4851 has the ability to communicate with a variety of common instrument management software packages, allowing users to remotely access information in HART devices to diagnose field equipment issues and optimize plant assets, resulting in significant operational improvements and immediate maintenance savings.

APPLICATION

Scalability: The MTL4851 module offers 16 HART channels, which means it can connect up to 16 HART-compatible field devices. This modular design allows the system to scale as needed to accommodate industrial applications of different sizes.

Flexibility: Each MTL4851 module can be used with other MTL4852 secondary interface modules, further increasing the number of connected HART devices. This flexibility allows the system to be configured and expanded according to specific application requirements.

Communication efficiency: The MTL4851 module supports automatic baud rate detection and can effectively communicate with a variety of HART devices. Multiple HART channels allow simultaneous communication with multiple devices, increasing the efficiency of data acquisition and control.

Redundancy: In critical applications, multiple HART channels can provide redundant communication paths, increasing system reliability. If one channel fails, the other channels can continue to work, reducing system downtime.

Diagnosis and maintenance: Multiple HART channels in the MTL4851 module allow for more detailed diagnosis and maintenance of connected devices. Through HART communication, the configuration, status and diagnostic information of the device can be accessed for easy monitoring and maintenance.

System integration: In complex industrial control systems, the MTL4851 module can be integrated with a variety of DCS and PLC systems, providing a unified interface to manage connected HART devices. This integration improves the manageability and maintainability of the system.

Cost effective: While there is a limited number of channels for a single MTL4851 module, its modular design allows modules to be added according to actual demand, thus achieving cost effectiveness without sacrificing performance. Users can gradually scale the system as needed, rather than investing in a large, expensive system from the start.

Security: In applications where high security is required, multiple HART channels can provide an additional layer of security. For example, in some industrial processes, multiple sensors may be required to monitor the same parameter to ensure the accuracy and reliability of the data.
