Henry Engineering SUPERELAYII



LED/AC Tally light utility control interface


BSW has a complete Internet Radio solution, ready to go, for you, to get you broadcasting on the www's in no time.

Superelay II is a multi-circuit controller for any application where numerous circuits, including AC line voltage, need to be switched simultaneously. It is ideal for controlling “On The Air” tally lights and switching the various equipment functions that need to be controlled when, for example, the microphone in a broadcasting studio is turned on.

Superelay II provides six isolated SPDT relay outputs, plus AC and DC Tally Light outputs that can be set to flash. The AC Tally Light output can supply up to 200 watts of line voltage, and is switched with a synchronous solid-state relay to prevent electrical noise or arcing. The DC Tally Light output can supply up to 300mA at 12V DC; it can also “sink” up to 1A of current if used with an external power source. All relay and Tally Light outputs switch simultaneously.
