STS Connection relay AR 102 (60604) for analog PBX

Connection relay AR 102 for telecommunication networks (DE)

Note:
The STS connection relay AR 102 (60604) does not work on the analog port of the AVM FritzBox (relay circuit is not triggered). This is because the FritzBox does not supply sufficient alternating call voltage for the AR102 at the analog port. The STS AR104 is the correct choice for these small IP-PBX Systems.
