I/O Modules
Note
If the employment of further DC 24 V EEx i Supply modules is necessary for
reasons of extent of utilization, four Separation modules (750-616) must be
used to guarantee the distance between the intrinsically safe segments.
Warning
The maximum current of the internal power jumper contacts is 10 A. When
configuring the system it is important not to exceed the maximum/sum
current. However, if such a case should occur, another supply module must be
added.
The analog input module 750-481/003-000 can be used with all
couplers/controllers of the WAGO-I/O-SYSTEM 750 (except for the economy
types 750-320, -323, -324 and -327).
Further Information
General information on explosion prevention is described in the manual in
section “Use in Hazardous Environments“!
