23/04/2026

Choosing the right PLC is not just about brand or price — it starts with the right I O planning, signal selection, expansion strategy, and panel design.

A poorly selected PLC can lead to:

I O shortage during commissioning
analog signal issues
communication bottlenecks
future expansion problems
higher maintenance time and cost

In our latest Help Centre article, we break down how to select the right PLC for industrial automation panels, including:
✔ digital and analog I O planning
✔ PNP vs NPN considerations
✔ communication requirements
✔ CPU performance and scan time
✔ serviceability and future maintenance

If you design, build, maintain, or upgrade automation panels, this guide will help you make better engineering decisions from the start.

22/04/2026

A reliable control panel starts with a reliable enclosure.

Many field issues are not caused by PLC logic or wiring mistakes alone — they begin with poor thermal management, weak IP protection, and bad component placement inside the cabinet.

Our latest Help Centre article covers:

internal heat buildup
airflow and cooling logic
IP protection selection
condensation and dust risks
enclosure sizing
component placement best practices

Not every control panel fault is a PLC logic problem.

Many intermittent issues come from electrical noise, poor grounding, and weak signal integrity inside the panel.

Our latest Help Centre article covers:

sources of electrical noise
PE vs 0V/common basics
analog and communication signal issues
shielding and cable segregation
grounding best practices
practical troubleshooting steps

20/04/2026

Good control panel protection is not just about adding one MCB at the incoming side.

Real reliability comes from proper protection coordination — using the right mix of MCBs, fuses, DC branch protection, and fault isolation so that one field fault does not shut down the entire panel.

Our latest Help Centre article covers:

MCB vs fuse use cases
overload vs short-circuit protection
DC branch protection
selective tripping concepts
protection of PLCs, HMIs, and field circuits
fault isolation best practices
