Application

Applications

Weighing, motors, burners, feeding — the working conditions these controllers and modules actually run in, taken from the selection guide.

Packaging machinery

Film feeding, sealing and synchronisation for flow wrappers and cartoners

Weighing & checkweighing

Weight capture and judgement for dosing, checkweighers and silo weighing

Motor protection

Current transformers sense three-phase currents up to 50A, with overload and phase-loss detection

Gas-fired equipment

Temperature setting, ignition control and flame detection for ovens and furnaces

Vibratory feeding

Bowl feeder magnet intensity adjustment and dual-head feed sequencing

DC motor equipment

Forward / reverse, speed and brake control for 24V brushed motors

3C & test fixtures

Sequence control, pass / fail judgement and data logging for test fixtures

Custom automation

Process-specific control boards and dedicated controllers, delivered with fixed logic

Service Process

ServiceProcess

Clear deliverables at every step, from requirement sign-off to volume delivery — less back-and-forth for everyone.

Requirement review

We confirm I/O count, communication, operating environment and installation space, and produce a requirement list.

Solution & selection

We propose controller and module combinations with wiring plans and quotations, then confirm the technical agreement.

Prototyping & validation

Samples or small pilot batches, with joint debugging and process validation on your side.

Volume delivery

Scheduled production and 100% inspection before shipment, with long-term spares and technical support.
