Internal Bus Expansion Module: Left Side OM757 for Enhanced Network Assembly

The OM757 module is designed together with the OM756 module and the connection cable to divide the network node assembly into several separate assemblies with one common controller and is mounted on a DIN rail in the leftmost position of the assembly segment. The OM757 is also used to generate the internal bus supply voltage (FBUS) for the Bus Terminals. +5 V is generated from the 24 V DC voltage The module has terminals for potentials of the supply buses.
