  Slim type with more practicability and convenience After PLANET ISW/IFT Fast Ethernet Switch/Converter series become popular, PLANET has released the advanced industrial hardened Fast Ethernet Switch series with slim type, IP30 metal case. The compact, IP30 standard metal case allows either DIN rail or wall mounting to have the efficient use of cabinet space. The ISW-501T, one of the new models, is equipped with five 10/100Mbps auto negotiation ports and operates reliably in heavy industrial demanding environments.   Stable operating performance under difficult environments The ISW-501T 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. Being able to operate under the temperature range from -40 to 75 degrees C, the ISW-501T can be placed in almost any difficult environment. The ISW-501T also possesses an integrated power supply source with wide range of voltages (12 to 48V DC) for worldwide high availability applications requiring dual or backup power inputs.   Robust switch performance The ISW-501T offers high performance switch architecture. With the five 10/100Mbps Fast Ethernet ports providing non-blocking switch fabric and wire-speed throughput as high as 1Gbps and the 2K MAC Address table, the ISW-501T can perform wire-speed packets transfer without risk of packet loss. The flow control function enables the ISW-501T to provide fast and reliable data transfer.   All of the RJ-45 copper interfaces in the ISW-501T support 10/100Mbps auto negotiation for optimal speed detection through RJ-45 Category 3, 4 or 5 cables. The standard auto-MDI / MDI-X support can detect the type of connection to any Ethernet device without requiring special-through or crossover cables.

  The PLANET ISW-504PT PoE Industrial Ethernet Switch is designed to transmit power and data over single Ethernet cable to remote PoE capable devices and operates reliably in heavy industrial demanding environments. The ISW-504PT provides 5 10/100Mbps copper ports with 4-Port IEEE 802.3af Power over Ethernet inject interfaces delivered in an IP-30 rugged strong case. Supporting up to 15.4Watts power per port for any remote IEEE 802.3af powered device (PD) such as PoE IP cameras and PoE wireless LAN access point, the ISW-504PT is an ideal solution to deploy surveillance system and wireless service in climatically demanding wide temperature range(-40 to 75 Degree C)environments.   IEEE 802.3af Power over Ethernet PSE Industrial Switch   PoE feature is more often supported in the industrial Ethernet devices for efficient operation in harsh environments. The ISW-504PT in-line power follows standard IEEE 802.3af and allows giving power to 4 PoE compliant devices at the distance up to 100 meters through the 4-pair Cat 5 / 5e UTP wire. With Data and Power over Ethernet from one unit, the ISW-504PT shall reduce cables deployment and eliminates the need for dedicated electrical outlets on the wall, ceiling or any unreachable place. A wire carries both data and (power lowering), the installation costs, simplifying the installation effort and eliminating the need for electricians or extension cords.Furthermore, there is only 24V DC input in some industrial environments, the ISW-504PT series supports 24V DC or 48V DC dual voltages input and able to provide more wide range of industrial IEEE 802.3af PoE applications.   Wide Temperature conquers installation in harsh environments The ISW-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. Being able to operate under wide temperature range from -40 to 75 Degree C, the ISW-504PT can be placed in almost any difficult environment. It also offers dual-redundant, reversible polarity 24V DC or 48V DC power inputs for high availability applications requiring backup power inputs.     Robust Switch performance The ISW-504PT offers high performance switch architecture with 5 10/100Mbps UTP ports. It provides non-blocking switch fabric, wire-speed throughput as high as 1Gbps and the 2K MAC Address table. It also performs wire-speed packets transfer without risk of packet loss and the Flow Control function is default enabled to provide fast and reliable data transfer. All of the RJ-45 copper interfaces support 10/100Mbps Auto-Negotiation for optimal speed detection through RJ-45 Category 3, 4, 5, 5e or 6 cable. The standard Auto-MDI/MDI-X support can detect the type of connection to any Ethernet device without requiring special straight or crossover cables.
