The devices support operation from power sourcing equipment meeting the 802.3at class 4 (30 W) or 802.3af class 3 (15.4 W) IEEE Power Over Ethernet (PoE) standards. These are commonly referred to as PoE+ and PoE, respectively by equipment providers.
Peak power draw must be strictly maintained within the power envelope of the power-sourcing equipment. If the external light connector is enabled in external light mode, the vision system generates 24 V to power the external light with the following limitations in place:
Simultaneous activation of the internal and external illumination is not permitted.
Auto-strobe lights with high pulse current are not supported and trip over current protection in the vision system, disabling the external light connector.
External lights with adjustable intensity may be used, provided the peak current draw is below the over-current protection limit. It is recommended to start with the lowest intensity setting and work upwards or to use the auto-tune feature.
Power over Ethernet requires an extra regulation step which incurs additional thermal buildup within the device. As a result, the specified operating temperature range is reduced when powered by PoE.
