2.4.1 Input Connection
The i-PORT has the ability to use external sensors as triggers, that is, scans or event messages can be
activated by events. External sensors such as photo sensors, motion detectors, etc. (with NPN-output) can
be used.
The input is set by connecting it to Ground. The sensor can be managed from the i-PORT; power is available
from the i-PORT’s power supply (see below). Maximum resistance across Ground is 560 Ohms, in order to
set the input.
2.4.2 Output Connection
The i-PORT also has the ability to intervene in processes. Lamps, sirens, gates, etc. can be switched using
the relays.
The maximum breaking capacity of the potential-free relay contacts is 30W (DC) and 62.5 VA (AC). Contact
load is 1A/30VDC and 0.5A/125VAC. The “Out” and “Com” clamps are connected when the relays are
switched on.
