(15) Description of the equipment
The Type 3965-1131 PROFIBUS DPplus Solenoid Valve Island consists of the
Type 1170-3010 Power Supply Module, the Type 1170-3184 CPU Module and the
Type 1170-3185 NAMUR Module. The solenoid valve island is designed as a commu-
nication interface between the internal communication lines within the system and the
external RS-485-IS bus system (PROFIBUS DP). The NAMUR module is designed for
connection of inductive proximity sensors and assessing their signals.
The solenoid valve island is designed for use inside hazardous areas.
The electric data of the individual modules are summarized in the following.
