High Power PoE Solution for Harsh Industrial Network  The IGS-504PT is the smallest industrial-grade 4-Port PoE+ Switch in PLANET industrial PoE product line and is specially designed to be installed in a narrow environment. It provides up to 120-watt 802.3at PoE+ output capability and wire-speed Gigabit performance even in the harsh industrial environment. With four 10/100/1000BASE-T ports featuring IEEE 802.3at PoE+ and one extra 10/100/1000BASE-T RJ45 copper interface for uplink connection.   The power system of the IGS-504PT supports 48~54V DC power input for power redundancy and operational flexibility. It comes with a total power budget of up to 120 watts for different kinds of PoE applications and operating temperature ranging from -40 to 75 degrees C in a rugged IP30 metal housing.   Plug and Play High Power Sourcing Solution Complying with the IEEE 802.3at Power over Ethernet Plus technology, the IGS-504PT provides up to 30 watts of PoE output power to allow users to flexibly deploy standard and high powered devices simultaneously with no need of software configuration. Furthermore, the IGS-504PT can extend much longer distance by using PLANET PoE Extender for powering up the PoE PD devices which can be installed over more than 100 meters away. By daisy-chaining multiple PoE extenders, it offers the great flexibility of doubling, tripling or quadrupling the distance of PoE network.   Dual Power Input for High Availability Network System The IGS-504PT features a strong dual power input system with wide-ranging voltages (48V~54V DC) incorporated into customer’s automation network to enhance system reliability and uptime. In the example below, when Power Supply 1 fails to work, the hardware failover function will be activated automatically to keep powering the IGS-504PT via Power Supply 2 without any break of operation.   Small but Strong Enough for Any Hardened Environment With the IP30 industrial metal case, the IGS-504PT provides a high level of immunity against electromagnetic interference and heavy electrical surges which are usually found on plant floors or in curb-side traffic control cabinets without air conditioning. It features a ventilated construction in which a cooling fan is not necessary, thereby making its operation noiseless. Being able to operate under the temperature range from -40 to 75 degrees C, the IGS-504PT can be placed in almost any difficult environment.   Robust Protection The IGS-504PT provides contact discharge of ±6KV DC and air discharge of ±8KV DC for Ethernet ESD protection. It also supports ±6KV surge immunity to improve product stability and protects users’ networks from devastating ESD attacks, making sure the flow of operation does not fluctuate.   Flexible and Easy Installation with Limited Space The compact-sized IGS-504PT is specially designed to be installed in a narrow environment, such as wall enclosure. It can be installed by fixed wall mounting or DIN rail, thereby making its usability more flexibly and easily in any space-limited location.
