For terminal operators, process engineers, automation integrators, and EPC specifiers who require robust connectivity, safe and flexible expansion, and long-term asset protection, the MCG 3210i Intelligent Field Interface Card Rack provides a reliable and scalable solution. This central hub links L&J host systems with multiple field devices using the Tankway communication protocol. Unlike standard systems, the MCG 3210i isolates each field branch to prevent a single fault from affecting the rest of the system, while built-in surge suppression safeguards valuable control room equipment. This modular design ensures uninterrupted communications and seamless integration of both new and legacy devices across complex tank farms, refineries, and terminals.
By isolating each field branch, the system prevents a single cable fault from causing cascading failures, ensuring continuous operation.
Integrated surge suppression safeguards host systems against transient voltages and wiring errors, protecting your investment and reducing costly downtime.
Each Field Interface Card (FIC) board supports and communicates with up to 128 devices, allowing for simplified system expansion with a minimal hardware footprint.
Supports RS-232 communication and can be upgraded with Intelligent Field Interface Cards (IFIC) for enhanced, real-time data delivery directly to the MCG 3900 Gauging System.
Provides robust conversion and protection of field signals, ensuring uninterrupted and secure communication.

We have tried to answer the most common questions we are asked here.
A Field Interface Card Rack, like the MCG 3210i, is a central hub that provides power, communication, and fault isolation for multiple field devices. It’s a critical component in tank gauging systems because it acts as a centralized brain, ensuring that a problem with one device or cable doesn’t bring down your entire system, thereby protecting data integrity and operational uptime.
The MCG 3210i has built-in surge suppression that protects your control room equipment from voltage spikes caused by lightning strikes or wiring errors in the field. This significantly prolongs the service life of your valuable host systems and prevents costly equipment damage and downtime.
Yes. The rack is designed for long-term use and backward compatibility. It supports the standard L&J Tankway protocol, which allows it to communicate with both modern gauges and legacy devices, making it an excellent solution for facilities looking to upgrade their host system without replacing their entire installed base of field instruments.
