Device specifications
Terminal units (AC500 standard) > TU531 and TU532 for I/O modules
The terminals 1.8 to 4.8 and 1.9 to 4.9 are electrically interconnected within the terminal unit
and always have the same assignment, independent of the inserted module:
● Terminals 1.8 to 4.8: process supply voltage UP = +24 V DC
● Terminals 1.9 to 4.9: process supply voltage ZP = 0 V
The assignment of the other terminals depends on the inserted communication interface module
(see the description of the respective module used).
The supply voltage of 24 V DC for the module's circuitry comes from the I/O expansion bus (I/O
bus).
