The ALS module provides a source of plus and minus 15Vdc needed by the operational amplifier and digital logic circuits, while DLS module provides the additional +15 Vdc capacity for driving large amounts of digital logic circuits and for extra trip outputs.
The ALS-1 and DLS-1 power supply modules are used as direct replacement for the ALS and DLS power supplies and isolate the relay system logic and sensing circuits from the station battery.
