"Single Master":
1 AS-i network, 1 AS-i Master.

"Double Master":
2 AS-i networks, 2 AS-i Masters.

"Optional AS-i Safety coupling circuit":
2 AS-i networks, 1 AS-i Master.

1 AS-i network, 1 AS-i Master
1 power supply, 1 gateway for 2 AS-i networks, inexpensive power supplies

"yes, max. 4 A/AS-i network":
Cost-effective power for 2 AS-i networks with 1 power supply (optionally supply of multiple Single Gateways by 1 power supply).

Operation with short cable lengths with standard 24 V power supply possible.


"no, max. 8 A/AS-i network, redundant supply":
1 AS-i power supply per AS-i network. Gateway is powered in normal operation from one of the two AS-i power supplies.

Should one AS-i power supply fail, switching to the other AS-i power supply allows all the diagnostics functions to be maintained and the unaffected AS-i network continues to operate.

"no, max. 8 A/AS-i network":

1 AS-i power supply per AS-i network.

yes, max. 0,5 A/AS-i network, max. 8 A with AS-i power supply
Diagnostic and configuration interface
