Active and Passive Models

Lumberg Automation M12 Distribution Block Comparison

Compare M12 distribution blocks by network protocol, I/O capacity, connector type, housing width, and environmental protection. Use the guide below to narrow the options, then select a part number to view product details.

Choose an active M12 block when...

The field block must exchange data directly with a control network or IO-Link system. Compare supported protocols, available input/output channels, and the required power and bus connectors.

Choose a passive M12 block when...

Several field-device signals need to be consolidated into one home-run cable or M23 connection. Compare port count, cable length, LED indication, PNP/NPN configuration, and shielding.

Quick M12 Distribution Block Selection Checklist

1. Function: Active network node or passive wiring block 2. Capacity: Required inputs, outputs, or IO-Link ports 3. Connections: Match power, bus, and field-device interfaces 4. Environment: Verify the needed IP rating and housing width

Understanding the Comparison

An active Lumberg Automation M12 distribution block processes and exchanges field I/O data through an industrial communication protocol. A passive block acts as a centralized wiring point, routing connected sensor and actuator signals through an M23 interface or fixed control cable.

Before ordering: Confirm the controller protocol, signal direction, port count, connector coding, and power interface. IP ratings apply only when the block is installed with correctly rated mating connectors and unused ports are properly sealed.
