The module has 4 miniature fuses providing line protection. Each fuse is associated with an LED. The fuses are monitored via evaluation logic, and the state of each circuit is announced to the related LED. The contact pins 1, 2, 3, 4 and L- on the front side serve to connect L+ resp. EL+ and L- to supply the IO modules and sensor contacts. The contacts d6, d10, d14, d18 serve as rear terminals for 24 V supply of one IO slot each. If all fuses are in order, the relay contact d22/z24 is closed. If a fuse is not equipped or faulty, the relay will be deenergized. Via the LEDs, faults are announced as follows:

Fuses max. 4 A slow blow Switching time approx. 100 ms (relay) Loadability of the relay contacts 30 V/4 A (continuous load) Residual voltage in 0 V case of fuse tripped Residual current in 0 mA case of fuse tripped Residual voltage in max. 3 V case: missing supply. Residual current in < 1 mA case of missing supply. Space requirement: 4 TE. Operating data: 24 V DC: 60 mA
