Panel equipment products
Choosing control panel components
| Component | Function | Selection note |
|---|---|---|
| 24 VDC power supply | Powers PLCs, sensors, relays | Size 20–30 % above total load; prefer a DC OK contact |
| 4–20 mA splitter/isolator | One signal to two devices, breaks ground loops | 3-way isolation input – output – supply |
| E-stop and guard | Safe stop, prevents accidental actuation | Red on yellow, latching, twist to release |
| LED light, door switch | Maintenance lighting | Switches on when the door opens |
| Controllers, buttons, pilot lights | Operation and status indication | EN 60204-1 colours: red – emergency, yellow – abnormal, green – normal |

FAQ
How do I size a 24 VDC power supply?
Add up the current of PLCs, sensors, relays and solenoid valves and choose a supply 20–30 % larger; loads with high inrush need extra margin.
When is a 4–20 mA isolator needed?
To send one signal to two places (PLC and display), when devices sit at different ground potentials, or when the signal is noisy or drifting.
