Power Supply Concept

Ex i XTR I/O modules shall only be supplied via "Power Supply 24 VDC
Diagn for Ex I XTR Modules"
Ex i XTR I/O modules shall only be operated with a "Power Supply 24 VDC
Diagn for Ex I XTR Modules" 750-606/040-000.
Keep the air and creep distances between intrinsically safe segments!
The maximum current available from the 750-606/040-000 "Power Supply
24 VDC Diagn for Ex i XTR Modules" is 1 A.
If the use of further 750-606/040-000 is necessary for reasons of extent of
utilization, 4 Separation Modules (750-616/040-000) must be used to guarantee
the distance between the intrinsically safe segments.
Do not exceed maximum current via power contacts!
The maximum current available from the "Power Supply 24 VDC Diagn for Ex i
XTR Modules" 750-606/040-000 is 1 A. Greater currents can damage the power
contacts. When configuring the system, ensure that this current is not exceeded.
If exceeded, an additional 750-606/040-000 must be used.
Further information about explosion prevention!
Further information about explosion prevention can be found in section "Use in
Hazardous Environments"!
The Ex i XTR I/O module receives the 24 V voltage supply for the field level from
an upstream Ex i XTR I/O module or from the "Power Supply 24 VDC Diagn for
Ex i XTR Modules" 750-606/040-000 via the power contacts used as blade
contacts. It then provides this potential to subsequent I/O modules via the power
contacts used as spring contacts.
