Product Description
The primary switched mode DIN rail power supply SLA4.100 specifically supplies AS Interface ® systems with energy. The AS-Interface bus tech- nology 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 communica- tion signals of the individual network participants are modulated onto the supply voltage. For this purpose, specific power supply units with in- tegrated data decoupling are required for AS-Interface systems.
