The terminals 1.8 and 2.8 as well as 1.9, 2.9 and 3.9 are electrically interconnected within the
terminal unit and have always the same assignment, independent of the inserted module:
Terminals 1.8 and 2.8: Process supply voltage UP = +24 V DC
Terminal 3.8: Process supply voltage UP3 = +24 V DC
Terminals 1.9, 2.9 and 3.9: Process supply voltage ZP = 0 V
The assignment of the other terminals is dependent on the inserted communication interface
module.
