The primary switched mode DIN rail Power Supply SLA4.100 specifically 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 Power Supply units with integrated data decoupling are required for AS Interface® systems.
