MTL MTL4850 - MTL Fieldbus Isolator

MTL4850-MTL Fieldbus Isolator is a device specially designed for industrial automation, which aims to realize efficient isolation and redundant communication of PROFIBUS-DP network. Its main features include:

Support PROFIBUS-DP protocol: MTL4850 can communicate with PROFIBUS-DP master station and slave station equipment to ensure the reliability and real-time performance of data transmission.

Dual network connection: The device provides two independent PROFIBUS network interfaces to support redundant configuration, thus improving the stability and reliability of the system.

Modular design: MTL4850 supports accommodating two bus interface modules, which is convenient for expansion and maintenance.

Installation flexibility: the equipment can be installed on DIN guide rail or panel to meet different installation requirements.

High-speed data transmission: support communication rate up to 12 Mbaud, ensuring rapid response to changes in process conditions.

Redundant operation and diagnosis function: MTL4850 supports redundant operation, and can monitor the running status of the main BIM and resume communication when the system is restarted or cold started.

Easy configuration: parameterized configuration through GSD file or PROFIBUS master station simplifies the equipment setup process.

As a high-performance PROFIBUS-DP isolation module, MTL4850 is widely used in the field of industrial automation, such as PLC control system, DCS control system, industrial robot, etc., for monitoring production equipment, controlling process flow and managing power equipment.

When an eight-input Digital module is configured for counter 

operation, PROFIBUS presents the digital inputs as word data. The 

most significant byte contains the states of inputs 1–8 and the least 

significant byte contains all 0s. 

This behavior applies to the following modules: 

8109-DI-DC 

8110-DI-DC 

8111-DI-AC 

8112-DI-AC 

8113-DI-AC 

8114-DI-AC 

8220-DI-IS (8-input configuration)
