The scope of supply of the IM 151-1 includes the termination module that must be plugged into the last I/O module of the ET 200S. Up to 6 spare fuses (5 x 20 mm) for the PM-E power module 24 V DC to 230 V AC can be accommodated on this module.
IM 151-1 interface module enables connection of the ET 200S to PROFIBUS DP and handles communications between the modules and the higher-level DP master autonomously.
