Power Supplies
The TC8518 offers several different power input options (12 VDC, 24 VDC, -48
VDC, 110V/220V). Each configuration allows for two power supplies to share the
load. The unit can still operate with one power input (either A or B).
Important
Read and only connect a supply voltage that corresponds to the
type plate of your device. Make sure that the contact load capacity
of the signal contact is not exceeded.
