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