applications

Short description
The primary switched mode DIN rail DC/DC converter SLAD4.100 specif®
ically supplies AS Interface systems with energy. The AS-Interface bus
technology allows to connect up to 62 participants to a control and to
supply them with energy with a single two-conductor cable.
When connecting slaves, the yellow AS-Interface cable offers the high

degree of protection IP67 in conjunction with the insulation displacement. The communication signals of the individual network participants
are modulated onto the supply voltage. For this purpose, specific DC/DC
converter units with integrated
data decoupling are required for AS-Interface systems.
