One FOB alarm module each with 64 analog/digital output signals is possible per link of an ibaFOB output card. The FOB alarm module only supports the 3 Mbit mode. If you add an FOB alarm module to a link of an ibaFOB-D card, then the link automatically switches to the 3 Mbit mode. Per FOB alarm module, you can configure up to 64 analog and 64 digital signals and send to iba-capable devices with 3 Mbit mode, such as ibaLink-SM-64-io, ibaLink-SM128-i-2o, ibaPADU-8-O or ibaNet750-BM.
