The 1756-MVID module expands the functionality of your ControlLogix system. It serves as a multi‑vendor interface (MVI) that connects Allen‑Bradley controllers to external serial equipment. This module includes a development CD‑ROM, which provides useful tools for configuration. The 1756-MVID draws 800 mA at 5.1V DC and only 30 mA at 24V DC from the backplane. Its power dissipation is a low 4 Watts. Consequently, it operates efficiently without generating excessive heat. Additionally, this module carries important certifications: CE, c-UL-us, and N223. Therefore, you can safely install it in industrial environments, including hazardous locations. The front panel includes LEDs for status indication, making troubleshooting quick and straightforward.
The 1756-MVID delivers reliable performance for mixed‑vendor communication tasks. Below are the detailed technical parameters:
Module Type: Multi‑vendor interface module
Power Dissipation: 4 Watts
Backplane Current (5.1V DC): 800 mA
Backplane Current (24V DC): 30 mA
Enclosure Type: None (open‑style)
Shock Rating: 30 G
Vibration Rating: 2 G from 10 to 500 Hz
Relative Humidity: 5% to 95%, non‑condensing
Operating Temperature: 0 to 60 °C (32 to 140 °F)
Storage Temperature: –40 to 85 °C (–40 to 185 °F)
Certifications: CE, c-UL-us, N223
Furthermore, the 1756-MVID is approved for use in hazardous locations. This makes it ideal for demanding industrial settings like oil and gas, chemical processing, and mining. Remember that this is a Series A component, known for its rugged and simple design.
Proper environmental conditions ensure long service life for the 1756-MVID. Although it has an open‑style enclosure, the module is built to withstand tough industrial conditions. First, the vibration rating of 2 G from 10 to 500 Hz means it resists common machinery vibrations. Second, the 30 G shock rating protects against sudden impacts. Third, the wide operating temperature range from 0 to 60 °C covers most factory floors. For storage, you can keep the module between –40 and 85 °C without damage. Meanwhile, keep relative humidity between 5% and 95% and avoid condensation. Additionally, the 1756-MVID requires installation inside a ControlLogix chassis. The chassis provides the necessary physical protection and backplane connection.
Installing the 1756-MVID follows standard ControlLogix practices. First, disconnect power from the chassis. Next, select any available slot in your ControlLogix chassis. Insert the 1756-MVID module and push firmly until it seats fully against the backplane. Then tighten the retaining screws at the top and bottom. After installation, connect the serial adapter cables (included) to the three DB9 ports. Use the jumper on the side of the module to select the correct protocol: RS‑232, RS‑422, or RS‑485. Finally, power up the chassis. Check the front LEDs for proper startup indications. For advanced configuration, use the included CD‑ROM. This CD contains development tools specifically for the 1756-MVID. Boot messages should appear on your connected terminal if setup is correct. If no messages appear, verify the Setup jumper position and all cable connections.

1. What is the main difference between the 1756-MVI and the 1756-MVID?
The 1756-MVID includes a development CD‑ROM with configuration tools. The standard 1756-MVI does not include this CD. Otherwise, both modules offer similar serial communication capabilities.
2. Can I install the 1756-MVID in any slot of the ControlLogix chassis?
Yes. The 1756-MVID works in any slot of the ControlLogix chassis. There are no restrictions on slot selection. Simply insert it into an available position.
3. Is the 1756-MVID approved for hazardous locations?
Yes. The 1756-MVID carries certifications including c-UL-us and CE. It is specifically approved for use in hazardous industrial locations. Always check local regulations before installation.
4. What should I do if no boot messages appear on my screen?
First, verify that the Setup jumper is installed correctly on the 1756-MVID. Next, check all cable connections between the module and your terminal. Then power cycle the chassis. If problems persist, consult the installation instructions booklet.
5. What is the maximum shock rating for the 1756-MVID?
The 1756-MVID has a shock rating of 30 G. This makes it highly resistant to sudden impacts and mechanical shocks commonly found in heavy industrial environments.
