WAGO-I/O-SYSTEM 750 Device Description 13750-610 24V DC Power Supply/Fuse/Diagn.ManualVersion 1.1.03 Device Description750-610 (24V DC Power Supply/Fuse/Diagn.)The supply module750-610 (24V DC Power Supply/Fuse/Diagn.) provides 24VDC field side power to the downstream modules.The power supply is derived from an external source via the 24 V, 0 V and ground(earth) terminals.The assignment of the connections is described in the “Connectors” section.The I/O module provides the 24V, 0V and earth potential to subsequent I/Omodules via the power contacts used as spring contacts.Both the potential groups and the individual modules within these groups can bearranged in any combination when designing the field bus node.The supply module (750-610) may only be used in connection with a suitable fuse(not included).Additional information on installing or replacing a fuse is available in the section"Startup and Service" > "Fuse Installation or Replacement".A green status LED indicates that the I/O module provides a 24V power supply tothe power jumper contacts. The status is only displayed when the fuse is intact.When the 24V power supply is available, a red error LED indicates a fuse defector error.The meaning of the LEDs is described in the “Display Elements” section.The supply module occupies two bits in the input process image.Bit 0 (operating voltage monitoring) is set when the 24V power supply to thepower contacts (CAGE CLAMP®) is available and the fuse is intact.Bit 1 (fuse monitoring) is set when a 24V power supply is applied to the powercontacts (CAGE CLAMP®), but the fuse is missing or defective.The I/O module 750-610 can be used with all fieldbus couplers/controllers of theWAGO-I/O-SYSTEM 750.
