The Sequential Switch System applies power to system components in desired time-delay sequence, minimizing the potential for tripped circuit breakers, blown fuses, or voltage spikes caused by simultaneous power application. The system is ideal for large sound reinforcement systems, electrical and electronic systems/controls and other signal chains that require sequential, power up and power down. The model SACR-191 is a six-circuit sequencer designed to sequentially activate the associated SACS-1 and SACS-5 117VAC power outlets.
Added flexibility is incorporated by providing both a 24 VDC output (for use with the SACS-1 and SACS-5) and a SPDT dry contact closure on each circuit which can be used for a variety of other applications. The built-in clock generator is adjustable (one to ten seconds) and provides a means of setting the turn-on/off delay of the six circuits. Screw terminals are provided for connecting the SACS-1 or SACS-5 power outlets to the SACR-191. In addition, terminals are also available to connect a remote sequence start/stop switch.
The cable necessary to interface the SACR-191 controller with the remote SACS-1 and SACS- 5 is two conductor cable 22-gauge min. per circuit (not included). The remote start/stop switch also requires a two-conductor, shielded cable 22-gauge min. (not included). NOTE: Regarding remote start/stop switch configuration. Remote start/stop switch MUST BE of a momentary type, use AtlasIED model HX11-P or equvalent (sold separately). HX11-P switch may be mounted to single gang stainless steel plate model S301 (also sold separately).
The SACR-191 is powered by an external 18 VAC power supply (included). Controls include a master power on/off switch, a sequence start/stop switch, master power indicator light, sequence status light and circuit status lights.
