IOT controller for diesel generator sets

A diesel generator is only as valuable as your confidence in its readiness. When the grid fails, planned or otherwise, the performance of your backup power infrastructure is not a variable you can afford to leave unmonitored. At Jcom-iot, our CoMonDGS series of IoT controllers brings real-time remote monitoring and data acquisition directly to your generator sets — delivering the operational visibility that transforms reactive maintenance into proactive asset management.

The CoMonDGS Series: Connected Control for Every Connectivity Environment

The CoMonDGS line has been purpose-designed for diesel generator monitoring, with each model offering the same core functionality and data depth while addressing the specific connectivity realities of different deployment sites. Whether your facility has wired Ethernet infrastructure, a stable 3G signal, or requires modern 4G LTE coverage, there is a CoMonDGS controller configured for your environment.

CoMonDGS v2.0 (Ethernet)

The foundation of the CoMonDGS series, the v2.0 delivers full-featured IoT monitoring over wired Ethernet — the natural choice for stationary installations within facilities that have reliable local network infrastructure. Data center backup systems, industrial plants, and commercial buildings with structured cabling benefit from the stability and bandwidth consistency that a wired connection provides. The v2.0 acquires all critical generator parameters and transmits them continuously to your monitoring platform without the variability of wireless signal dependency.

CoMonDGS v2.2 (3G Ethernet)

Where wired infrastructure is absent or impractical, the v2.2 extends CoMonDGS capability over 3G cellular networks while retaining a wired Ethernet fallback. Designed for remote sites, temporary installations, and facilities in areas with established 3G coverage, this model ensures that your generator data reaches your control center regardless of local network availability. A practical and cost-effective solution for distributed power assets across wide geographic areas.

CoMonDGS v2.3 (4G Ethernet)

For deployments that demand the fastest, most reliable wireless data transmission available, the v2.3 operates over 4G LTE networks with Ethernet connectivity as an additional channel. Suited to mission-critical installations, high-frequency reporting requirements, and sites where low-latency alerting is non-negotiable, the v2.3 represents the top of the CoMonDGS connectivity range — combining the depth of the series’ monitoring capability with modern cellular infrastructure.

What CoMonDGS Controllers Monitor

Every model in the CoMonDGS series is engineered to capture the full operational picture of your diesel generator set in real time:

• Engine parameters: RPM, coolant temperature, oil pressure, and engine runtime hours — the core indicators of mechanical health and operational state.
• Electrical output: Voltage, current, frequency, and load — ensuring your generator is delivering power within specification when it matters most.
• Fuel system: Fuel level and consumption rate monitoring to support refueling planning and detect anomalies indicative of leakage or theft.
• Battery and charging system: Starter battery voltage and charge state — one of the most common causes of generator start failure, now continuously tracked.
• Operational events: Automatic logging of start/stop events, alarm conditions, fault codes, and mode changes for complete audit trail and post-incident analysis.
• Remote alerts: Configurable threshold-based notifications delivered immediately when any parameter moves outside defined operational limits.

The Case for Continuous Generator Monitoring

Periodic manual inspections tell you the condition of your generator at one moment in time. IoT monitoring tells you everything that happened in between. For backup power assets — which may sit idle for extended periods and then be called upon to perform under load without warning — the gap between inspections is precisely where failures develop. Fuel contamination, slow battery degradation, coolant loss, and controller faults rarely announce themselves during scheduled checks. They surface at the worst possible moment.

A CoMonDGS controller closes that gap entirely, providing a continuous, timestamped record of your generator’s health and ensuring that your team receives an alert the moment a developing issue becomes detectable — long before it becomes a failure.
