Lowell Models SCS-4 and SCS-8 are compact and economical low voltage sequencers that combine with low voltage remote power controls and switches to provide time-delayed activation and de-activation of AC powered equipment that is on site or in a remote location. Sequencer chassis size is small for easy installation in a remote location or on a blank 2U rack panel. Sequence delay is screwdriver-adjustable with 0.5-10 seconds between steps. Sequencing is initiated by an external remote switch (order separately).
Model SCS-8: provides eight delayed closure circuits that activate in sequential order (1, 2, 3, 4, 5, 6, 7, 8) and deactivate in reverse order (8, 7, 6, 5, 4, 3, 2,1). Sequencing may be initiated by a single remotely located SPST maintained contact closure switch or by multiple SPST normally open momentary closure switches (order switches separately). A built-in slide switch allows for selection of single or multiple switch modes. LED indicators provide visual status of each control circuit as well as power verification. Also included is an auxiliary 24VDC, 300mA (max) output for remote indicators. Steel chassis measures 10"L x 3.281"W x 1.687"H and is finished in black powder epoxy. It includes mounting holes, operational diagram and a connected UL Listed power supply.
4-Step and 8-step low voltage sequencers combine with remote power controls and switches to achieve time delayed on/off activation of AC equipment.
Compact size surface-mounts nearly anywhere.
Low voltage connections allow for cost effective wiring and installation.
