The EM12-T supply module receives the DC 24 V supply voltage, e.g.
from a switch mode power supply, and distributes it to the mounted
circuit protectors via the integral connector arm of the REX12-T.
The potential-free auxiliary contact in the EM12-T indicates any
detected failures through the circuit protector, e.g. to the superordinate
control unit (CPU).
