Supports defect detection, target recognition and status judgment to improve on-site inspection efficiency.

Edge analysis and response:

Completes local data processing and fast response to reduce latency and improve real-time performance.

Multi-source data collaboration:

Integrates vision, sensor and control signals to support intelligent decision-making.

Unattended Wind/Hydro Power & Pump Stations

Stable in harsh conditions:

Industrial-grade hardware with integrated thermal management; key connectors are corrosion-resistant and built for long life, adapting to complex sites for long-term stable operation.

Multi-link remote interconnection:

Wired and wireless coordination ensures stable networking and backhaul for distributed sites, improving reachability and continuity of unattended systems.

Unattended O&M:

Connect the dedicated APP via Bluetooth for on-site debugging, parameter configuration and status viewing; combined with Wi-Fi/4G remote monitoring and data reporting, it reduces inspection frequency, shortens fault response time and lowers O&M costs.

High-end Equipment & Precision Motion Control

Quick-plug, no-disconnect maintenance:

Fast-release terminal design enables machine swap without disconnecting wiring for rapid recovery.

EtherCAT synergy:

Based on EtherCAT hardware coupling, it achieves high-speed deterministic communication between the controller and servo systems, supporting multi-axis coordination and precision sync for dispensing, mounting, assembly and inspection scenarios.

High-speed real-time control:

A high-performance multi-core processor and industrial control architecture stably execute complex logic and high-speed cyclic tasks, meeting the real-time control needs of high-end equipment under high-takt, high-consistency conditions.

Full-stack Cloud Connectivity

Multi-mode communication fusion:

Connects the device layer to the cloud, supporting EtherCAT, Ethernet, Wi-Fi, 4G and Bluetooth to cover real-time control, on-site access and remote networking for fast cloud onboarding and unified system integration.

Wireless O&M closed loop:

Bluetooth near-field maintenance plus cloud remote monitoring; the dedicated APP handles on-site debugging and parameters while Wi-Fi/4G reports status and output data, forming an on-site–remote–cloud O&M loop.

Reliable diagnostics:

Channel-level diagnostics for fast fault information retrieval.

Convenient Installation

Space saving:

INNOCTRL function modules are as thin as 12mm; the blade-style design saves cabinet space for demanding scenarios.

Fast install & removal:

Vertical plug-in, detachable terminals; different terminals just push in for wiring, with anti-slip grooves for quick removal.

Fast maintenance:

Tool-free wiring and rewiring to avoid fumbling without tools.
