Utilizing proven Siemens, Delta, and Schneider platforms, our Moratuwa-trained engineers deliver complete CAD schematics, fail-safe ladder programming, and real-time cloud analytics with local workshop support.
Automation & Connected Telemetry Solutions
From discrete machine sequence controllers to factory-wide SCADA data acquisition, we bridge rugged electrical engineering with modern cloud connectivity.
Multi-Brand PLC Programming
Robust, modular ladder logic and structured text programming for Siemens S7-1200/1500, Delta DVP/AS, Mitsubishi iQ-R/F, Schneider Modicon, and Omron controllers.
Touchscreen HMI & Scada Design
High-contrast, intuitive operator touchscreens (Delta DOP, Siemens Comfort/Basic, Weintek) featuring animated mimics, recipe management, batch logging, and multilevel password security.
Industrial IoT & Cloud Telemetry
Cellular 4G/GPRS & Ethernet edge gateways transmitting live production counts, motor health, and temperature readings over secure MQTT to cloud dashboards and smartphone alerts.
Custom Control Panel Fabrication
IP54, IP55, and IP65 industrial enclosures designed, laser-cut, powder-coated, populated, and neatly ferruled to IEC standards inside our Southern Province engineering workshop.
Predictive Condition Monitoring
Non-invasive installation of tri-axial vibration sensors and thermal monitoring probes on heavy motor bearings, gearboxes, and pumps to predict mechanical failure weeks in advance.
VFD & Motion Control Systems
Integration of variable frequency drives, stepper controllers, and closed-loop AC servos for high-speed synchronized conveyor lines, packaging feeders, and precision gantry axes.
Our 6-Stage Control Panel & Software Delivery Flow
We simulate all logic sequences and alarm scenarios on physical test rigs in our Galle workshop before field deployment.
Process Architecture & I/O Mapping
We analyze your machine sequence of operations, tally digital and analog I/O points, and select the optimal controller topology.
Electrical CAD & Panel Layout Drafting
Detailed drafting of 3-phase power distribution, 24VDC control circuits, terminal strips, and panel component layouts.
Workshop Assembly & Ferruled Wiring
Clean enclosure fabrication, DIN rail layout, wire ducting, and neat thermal-printed ferrule labeling inside our Galle workshop.
PLC Logic & HMI Graphics Development
Modular state-machine programming, interlock safety routines, alarm handling tables, and crisp vector HMI graphic screens.
Factory Acceptance Test (FAT) Simulation
Comprehensive bench testing with signal generators, dummy loads, and dry-run sequencing before the panel leaves our facility.
On-Site Commissioning & Operator Handover
Field wiring termination, sensor calibration, live production trials, operator training, and USB handover of all source codes.
