TOP 7 Industrial Engine Controllers for Site Power Management

NO.1 AIG701 Series Engine Controller

Brand Introduction

Industrial sites face a persistent challenge: unplanned engine startup failures caused by battery degradation, coupled with the difficulty of troubleshooting intermittent faults in harsh outdoor environments. The AIG701 Series addresses these pain points through integrated battery health monitoring and patented fault recording technology. This industrial-grade intelligent control solution focuses on high reliability, modular maintenance, and remote digital management for small-scale power units. The result is enhanced engine startup reliability and significantly reduced troubleshooting time through intelligent sensing and multi-terminal connectivity.

Core Technology & Products

The AIG701 Series represents a comprehensive control platform built on a 32-bit high-performance MCU architecture with IP65 protection grade certification and AC 2.2kV high-voltage insulation specification (leakage current ≤3mA).

• Battery Aging Detection Technology: Real-time monitoring of battery health detects aging rates before they compromise startup reliability. This proactive approach prevents equipment failures during critical moments by ensuring power source readiness at all times.

  

• Patented Black Box Technology: This proprietary innovation records complete operating data before and during alarm conditions, addressing the historical challenge of capturing intermittent fault causes. The system provides objective data evidence that reduces troubleshooting difficulty significantly.

• Multi-Terminal Management System: The standard Bluetooth module enables parameter modification and data viewing via mobile app, eliminating the need for specialized data cards in field environments. Support extends to PC commissioning through USB/TYPE-C interfaces, offering diversified remote and local control methods.

• Comprehensive Maintenance Management: Three sets of maintenance countdowns with dual-reminder modes (Hours/Months) prevent equipment wear caused by missed service intervals. The high-resolution dot-matrix LCD displays multiple parameters simultaneously in multiple languages, enhancing human-machine interaction clarity.

• Modular Structural Design: European-style terminal block connections lower labor costs for assembly, inspection, and replacement operations. The programmable I/O expansion supports multiple analog/digital inputs and 3 configurable relay outputs, offering high flexibility for external sensors and actuators.

• Flexible Startup Logic: Customizable timing for preheating, idling, and cooling sequences with dual success judgment criteria (Speed/Oil Pressure) ensures compatibility with diesel, gasoline, and gas engines across diverse fuel types.

Technical Specifications

The controller operates across DC 8V to 36V with exceptional temperature tolerance (-25℃ to 65℃) and minimal power consumption (≤1W standby at 24V DC, maximum 2W during operation). The PC material keypad panel provides waterproof, oil-proof, UV-resistant, and wear-resistant protection. J1939 protocol compatibility via CAN bus enables integration with modern engine management systems, while multi-level hierarchical protection logic (Warning, Shutdown, Trip) safeguards equipment integrity.
