The ProSoft Technology MVI69H-HART is a master communication module that complements the CompactLogix and MicroLogix processors to interface with HART devices when compatible. The ProSoft Technology MVI69H-HART master communication module commonly supports communications between Rockwell Automation modules and similar devices such as pressure devices, flow devices, temperature transmitters, and any other instruments included in any industrial process. The ProSoft Technology MVI69H-HART master communication module requires a current load of 800 milliamps maximum at 5 Volts DC. Its dimensions correspond to a standard 1769 single-slot module and it has a LED that indicates its status. The ProSoft Technology MVI69H-HART master communication module has 2 independent HART Bell 202 frequency shift keying and it can support up to 15 devices per port. These communication ports can be configured as a handheld configuration device.

The ProSoft Technology MVI69H-HART master communication module has the ability to initiate the hardware components of the processor, read module configuration, and set up the communication interface for the debug and configuration port. The mechanism for data transfer is through the input and output images. The update frequency of these images is determined by the users. All the data used by the ProSoft Technology MVI69H-HART master communication module is stored in its internal database. The ProSoft Technology MVI69H-HART master communication module is ideal for chemical and refining operations, gas refining, distribution systems, and offshore monitoring stations. This module can be included in a single slot and it can withstand a temperature range of 0 to 60 degrees Celsius. A relative humidity rating of 5 to 95% is recommended.
