As opposed to the 230 V primary side, circuit protection in the secondary circuit is often neglected. Another issue is that in the event of a failure of the 24 VDC voltage supply, standard mechanical circuit breakers often do not trigger. This may happen with long cables, for example.
The electronic circuit breakers from ifm monitor the circuit ideally and, if required, disconnect reliably. Individual branch circuits can be selectively disconnected, which allows a reduction of wire cross-sections in the load circuit of the switch-mode power supplies. The system has a modular structure and can be ideally adapted to the circuits of plant and machinery. The IO-Link version also allows evaluation of important diagnostic data.
The modules are available in fixed sizes 2 A, 4 A and 6 A.
Africa’s net-zero ambition must become operational Schneider Electric South Africa
