Which block do you need?

1
Passing a circuit through?

Use single-level feed-through blocks. Go multi-level when rail space is tight.

2
Grounding or splitting power?
Ground blocks bond to the rail; distribution blocks split one incoming feed into several outputs.
3
Special conditions?
Use ceramic blocks near heat, thermocouple blocks for sensor wiring, and DIN receptacles for service outlets. Don’t forget end plates, jumpers and markers.
