Long reach Ethernet creates holistic building management, says ADI
Long reach Ethernet connectivity is added to controllers, sensors and actuators in smart building networks, using the ADIN2111 10Base-T1L Ethernet device introduced by Analog Devices (ADI).
The ADIN2111 is designed for building automation networks. Digital, connected automation equipment enables holistic building management, said ADI, from heating ventilation and air conditioning to occupancy comfort.
Adding long reach Ethernet connectivity to controllers, sensors, and actuators delivers building management systems insights for more efficient and sustainable building management, said the company. The ADIN2111 is suitable for use within small, power-constrained edge devices. With a power consumption of 80mW, it provides up to 50 per cent power consumption savings. The 48-lead LFCSP, measuring 7.0 x 7.0mm is claimed to save up to 75 per cent in PCB real estate when compared to discrete implementations.
It has an SPI (serial peripheral interface) host interface which removes the need for a microcontroller with integrated MAC interface, advised ADI. The advanced packet filtering offloads the burden of priority traffic management from the processor via the 16 MAC addresses look up table, added the company.
The ADIN2111 is designed for daisy chaining data in line and ring networks using existing deployed single twisted pair cabling infrastructure within buildings. This contributes to a reduction in retrofitting costs, added ADI.
The device includes enhanced diagnostic features to reduce commissioning, installation and system downtime by troubleshooting problems quickly using the real time information on link quality and fault location. It is compliant to the IEEE 802.3cg standard to enable Ethernet connectivity over 1.7km of cabling, in addition to support for ring redundancy and soft real time protocols like Modbus/TCP, BACnet/IP and KNX.
The ADIN2111 is in full production now and is available in a 7.0 x 7.0mm package.
Analog Devices offers a suite of analogue and mixed signal, power management, radio frequency (RF) and digital and sensor technologies for customers worldwide operating in the industrial, communications, automotive, and consumer markets.
