Review MESA Isolated Remote Field I/o Card Sourcing Outputs

The Mesa 7i84 Isolated Remote I/O Card is a versatile and reliable solution for industrial automation applications that require isolating input and output signals to prevent electrical interference and ensure safety. This card is part of Mesa's 7000 Series of I/O systems, known for their rugged design and high performance.

The Mesa 7i84 card provides 8 input channels and 4 output channels, each with isolated AC or DC power supplies. The inputs support various signal types, including NPN and PNP transistor, current loop, voltage, and temperature inputs. The outputs can be configured as Form C or Form A relay contacts or as open/close contacts.

This card features Mesa's advanced Diagnostic and Reporting (DAR) technology, which continuously monitors input and output status, power supplies, and communication links. The DAR information is available locally and remotely via Ethernet, RS-232, or other communication protocols.

The Mesa 7i84 Isolated Remote I/O Card is designed for harsh industrial environments and can operate in temperatures ranging from -40 C to 70 C. It meets various safety standards, including CE, UL, and CSA. The card has a compact size of just 1.75 inches (44.45 mm) high, making it easy to install in limited spaces.

The card communicates with the control system via Mesa's Netbiter Protocol, which provides secure access to configuration, diagnostics, and data logging functions. The Netbiter software is available as a free download and supports multiple languages.

The Mesa 7i84 Isolated Remote I/O Card offers high reliability, accuracy, and safety for industrial automation applications where isolated I/O is essential. Its advanced features, rugged design, and easy integration with various control systems make it an ideal choice for industries such as power generation, water and wastewater, oil and gas, and manufacturing.

Mesa's 7i84 Isolated Remote I/O Card is a popular choice for industrial automation applications due to its features and benefits. Here are some pros and cons of buying this card:

1. Isolation: The primary advantage of the 7i84 card is its isolation feature. It provides galvanic isolation between the I/O points and the control system, ensuring the safety of personnel and equipment against electrical hazards.

2. Versatility: The card offers a wide range of input and output configurations, including analog input, discrete input, analog output, and discrete output. This makes it suitable for various applications and industries.

3. Ruggedness: Mesa's 7i84 card is designed to withstand harsh industrial environments. It has a wide operating temperature range and is resistant to vibration and shock.

4. Easy installation: The card comes with pre-configured software and a user-friendly interface, making it easy to install and configure.

5. Modbus communication: The card supports Modbus communication protocol, which is widely used in industrial automation and control systems.

1. Cost: The 7i84 card is more expensive than some other remote I/O solutions in the market.

2. Limited channels: The card has a limited number of channels, which may not be sufficient for larger applications.

3. Power requirements: The card requires a dedicated power supply, which may add to the overall cost and complexity of the system.

Mesa's 7i84 Isolated Remote I/O Card is a reliable and versatile solution for industrial automation applications that require galvanic isolation. Its rugged design, easy installation, and support for Modbus communication make it a popular choice among engineers and system integrators. However, its cost and limited channel capacity may be a concern for some users.

If you require galvanic isolation for your industrial automation application and have a budget for a high-end solution, the Mesa 7i84 Isolated Remote I/O Card is a recommended choice. However, if cost is a concern, you may want to consider alternative solutions with a lower channel count or without isolation. It's essential to evaluate your specific application requirements and budget before making a purchase decision.

Details:

Outputs have per output short circuit protection, over voltage clamps and driver chip thermal shutdown. Inputs can be programmed to other thresholds and filtering added if desired. Two MPG encoder inputs are provided as an option on four field. The inputs, outputs, and field power are galvanic ally isolated from the communications link.

The 16 outputs are 5VDC to 28VDC sourcing drivers with 300 MA maximum current capability. The 7I84 is identical to the 7I84D except that it has sourcing type outputs PNP. The 7I84 is a remote isolated 32 input and 16 output digital I/O card. The 7I84s outputs are suitable for driving relays, contractors, solenoids, and other medium power inductive or restive loads.
