40 SCOOP STUDIO - User manual 55 000 033 – Ed. D
This document is the property of AETA AUDIO SYSTEMS and can not be duplicated without authorisation March 2006
Remarks:
• Direction: I = input, O = output
• Relay/Opto 1 and relay / Opto 2 are the transparent contacts (relay
transmission)
• Relays and opto inputs are bi-directional, i.e. the polarity does not care
Input loop control current : 6mA ( max 100mA )
Resistance of input loop : 470Ohms ( current limiting series resistor )
Maximum switching voltage ( output ) : 400V peak
Maximum switching current ( output ) : 250mA
Resistance of output loop : 8 Ohms Max
A +5V power supply is available on the connector, with 100mA capacity, witch
can be used e.g. to power the input loops.
A +5V or +12V source may be connected directly on an input loop, because the
internal series resistor is dimensioned for this purpose. For a higher voltage
source, it may be necessary to limit the input current.
14.3. POTS Interface
The telephone network connection on Scoop Studio is a RJ 11 connector. ( Labeled
Analog )
