The Ex i XTR I/O module (750-439/040-000) receives the 24 V voltage supply
potential and the 0V potential 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 designed as blade contacts.
The Ex i XTR I/O module (750-439/040-000) provides these potentials to
subsequent I/O modules via the power contacts designed as spring contacts.
