The HIMA F7133 module is a 4-fold power distribution unit with fuse monitoring and L- distribution capabilities. Key features of the module include:
Miniature Fuses: Four miniature fuses provide line protection. Each fuse is associated with an LED indicator.
Fuse Monitoring: The fuses are monitored via an evaluation logic, and the state of each circuit is displayed on the corresponding LED.
Connection Points: Contact pins (1, 2, 3, 4, and L-) on the front side are used to connect L+ (EL+) and L- to supply the IO modules and sensor contacts.
Rear Terminals: Contacts (d6, d10, d14, d18) serve as rear terminals for the 24 V supply of each IO slot.
Relay Contact: If all fuses are intact, the relay contact (d22/z24) remains closed. If a fuse is missing or faulty, the relay de-energizes, and faults are indicated by the LEDs.
Note:
If the module is not wired, all LEDs will remain off.
If the input voltage is missing in circuits with connected paths, the state of the individual fuses cannot be determined.
