• 8 digital outputs with 2 A

• Source circuit

• 1-wire connections

• Power supply integrated in the module

• Integrated output protection

This module is equipped with 8 outputs for 1-wire connections. The outputs are designed for a source circuit. The nominal output current is 2 A.

The output power supply is fed directly into the module. An additional power supply module is therefore not necessary. There is no connection between the module and the I/O power supply potential on the bus module.
