Special designs, special uses
High degree of protection
3-phase, 24 V DC (ET200pro PS, IP67)
■
Overview
The SIMATIC ET200pro PS power supply unit with degree of
protection IP67 is used as the electronics/encoder supply and
load voltage supply of the new SIMATIC ET 200pro distributed
I/O system for use close to the machine without a cabinet. With
a signaling contact for "24 V OK" and "Overtemperature", as well
as a second plug-in connector for input voltage loop-through.
