IFS+803GSM-8PH24 is a managed, industrial grade, L2 PoE (Power over Ethernet) switch that provides 8x 10/100Base-TX PoE ports plus 3x 100/1000Base-X SFP. The PoE features enable power and data to be transferred via a single cable, hereby considerably reducing cabling and electrical wiring expenses. Housed in rugged DIN rail or wall mountable IP-30 enclosures, these switches are perfect choices for harsh environments, such as industrial networks, intelligent transportation systems (ITS) and are also suitable for many military and utility market applications where environmental conditions exceed commercial product specifications. The switch can also operate either at standard operating temperature range (-10 to 60°C) or at wide operating temperature range (-40 to 75°C) to fulfill the special needs of industrial automation applications.

PoE application with IEEE1588 PTP timing



Precision Time Protocol

IEEE 1588v2 PTP (Precision Time Protocol) is a packet-based timing technology. It is designed to provide precise timing for critical industrial applications and provides accurate frequency, phase, and time of day.

Accuracy is measured in the nanosecond range. The effects of network latency are greatly reduced by using a technique whereby the master and slave communicate with one another to cancel out a measured delay between the two nodes.

It is important that the transmission delays are almost constant over time (or at least change slowly) and that the delays are symmetrical between master and slave.  A stable network CoS with emphasis on Frame Loss, Frame Delay and Frame Delay Variation is essential.

Unique DC Power boost



Technical Notes

What is Power over Ethernet ?

Power over Ethernet, commonly abbreviated to PoE, is a technology that enables DC power to be delivered over the same twisted pair copper cabling as the data. This allows end devices such as IP phones, CCTV cameras and wireless access points to receive power across the network and avoids the need to install electrical cabling and a power source at the remote end.
