Reliable Industrial Ethernet Networks with Plug and Play Configuration:
PLANET’s new IGS-1820TF comes with high-density 16 10/100/1000BASE-T ports, 2 1000BASE-X SFP interfaces and redundant power system, it’s designed for heavy industrial demanding environments. Though it includes robust features designed for industrial Ethernet networks, its Plug and Play makes configuration easy. With the IP30-rated rugged but compact-sized case, it can operate stably under the temperature range from -40 to 75 degrees C and can be installed in any difficult environment without space limitation. Long-distance Fiber Uplink for Extension the Environment:
The two additional SFP slots built in the IGS-1820TF support 1000BASE-SX/LX SFP (Small Form-factor Pluggable) fiber transceivers to uplink to backbone switch in long distance. The distance can be extended from 550 meters to 2 kilometers (multi-mode fiber) and up to 120 kilometers (single-mode fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions. Environmentally Hardened Design:
With the IP30-rated rugged metal case, PLANET IGS-1820TF provides a high level of immunity against electromagnetic interference and heavy electrical surges which are usually found on plant floors or in curbside traffic control cabinets. Being able to operate under the temperature range from -40 to 75 degrees C, the IGS-1820TF can be placed in almost any difficult environment.  The IGS-1820TF also allows either DIN-rail or wall mounting for efficient use of cabinet space.  Robust Protection:
The IGS-1820TF provides a contact discharge of ±6KV DC and air discharge of ±6KV 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. Energy Savings:
The IGS-1820TF, integrated with advanced green networking technologies and IEEE 802.3az Energy Efficient Ethernet (EEE) protocol based power savings, is able to provide power savings of up to 50% but maintain high performance efficiently. Link Down power savings:
The Link Down power savings goes beyond IEEE specifications to automatically lower power consumption for a given port when it is not linked. With the Link Down power saving technology, the IGS-1820TF will automatically adjust power usage of the ports that are shut down or not connected to network device. Intelligent power scale based on cable length:
Intelligent power scale is an intelligent algorithm that actively determines the appropriate power level based on cable length. When the IGS-1820TF is connected with Ethernet cable shorter than 20m, a device can obtain maximum power savings because the IGS-1820TF would automatically detect the Ethernet cable length and diminish power usage. The connected device can substantially reduce the overall power consumption, which makes a significant contribution to energy savings. Dual Power Input for High Availability Network System:
The IGS-1820TF features a strong dual power input system with wide-ranging voltages (12V~48V DC or 24V AC) 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-1820TF via power supply 2 alternatively without any loss of operation.
