Overview

MCG 7030

For terminal operators, safety managers, compliance officers, and operations leaders who need reliable, real-time visibility into alarm conditions across tank farms and industrial storage facilities, the MCG 7030 Touch Panel Alarm Monitor provides a centralized, intuitive, and highly scalable alarm monitoring platform.

The system monitors up to 128 alarm probes on a single 4-wire data highway—or up to 48 individually wired probes when used in controller mode—supporting both wired MCG 1090 Level Alarm Probes and wireless MCG 1095 Wireless Alarm Probes. Unlike basic annunciator panels, the MCG 7030 operates as a full remote data acquisition station, consolidating alarm status, diagnostics, auto-test results, and alarm history into a single touchscreen interface.

Multiple communication ports enable seamless integration with Gauging, SCADA, or host systems, while an optional encrypted wireless link provides a fully independent high-level alarm system for remote or hazardous areas. The result is a safety-focused, compliance-ready alarm monitor that improves response time, reduces wiring complexity, and strengthens operational confidence across the entire facility.

Features

Immediate Alarms

High-Capacity Alarm Monitoring

Supports up to 128 multiplexed probes on a single 4-wire highway, enabling large-scale deployment without complex wiring.

Controller Mode for Individually Wired Inputs

Accepts up to 48 individually wired probes, ideal for applications requiring strict redundancy or independent verification.

Wired + Wireless Probe Compatibility

Works simultaneously with MCG 1090 (wired) and MCG 1095 (wireless) alarm probes, simplifying upgrades and mixed-technology environments.

Strong Security & Diagnostics

Real-Time Visualization & Diagnostics

Touch-panel interface displays active alarms, probe status, history logs, communications health, and self-test results.

Wireless Freedom

Secure Wireless Option

Optional frequency-hopping, encrypted wireless communication provides reliable, interference-resistant performance for independent high-level alarms.

Automatic Self-Testing Support

Initiates and logs mechanical self-tests for compatible probes, improving compliance and reducing manual field checks.

Multiple Host Interfaces

Multiple Host Interfaces

Provides communication ports for Gauging, SCADA, inventory, or automation systems using standard protocols.

Applications

  • Fixed-Roof Storage Terminals: Monitors high-level, high-high, or overflow alarms to prevent spills, environmental violations, and costly shutdowns.
  • Regulated Chemical & Fuel Storage: Provides certified alarm monitoring and detailed alarm history to support EPA, API, and state fire-code compliance.
  • Remote or Unmanned Sites: Centralizes alarms into SCADA for remote visibility, reducing staffing requirements without compromising safety.
  • Mixed Probe Environments: Ideal for facilities using a combination of wired and WirelessHART-based alarms, minimizing spare-parts variation and simplifying maintenance.
  • High-Reliability Alarm Systems: Supports redundant, self-checking alarm architectures for locations requiring independent verification layers.

FAQs

We have tried to answer the most common questions we are asked here.

The MCG 7030 is a versatile platform. It communicates with wired probes (like the MCG 1090) directly through a single, 4-wire data highway (multiplexing). For wireless integration, it communicates securely with the MCG 1095 Wireless Alarm Probes, allowing operators to leverage both technologies simultaneously within the same monitoring system.
The single 4-wire highway significantly reduces the amount of wiring needed compared to running individual wires for every alarm probe. This multiplexing capability cuts down installation costs, simplifies troubleshooting, and makes the system highly scalable for large tank farms (up to 128 probes).
When the MCG 7030 is paired with L&J’s compatible self-testing probes (like the MCG 1095), it utilizes the probe’s true mechanical self-check feature. The monitor initiates and logs the results of these physical tests, ensuring that the entire alarm system, not just the electronics, is fully functional and compliant.
Absolutely. Multiple communication ports and standard protocols allow the 7030 to feed alarm data, diagnostics, and event history directly into existing host systems.
The optional wireless link uses encrypted, frequency-hopping spread-spectrum communication to prevent interference and ensure secure, reliable alarm transmission.
