Hager KNX HTG911H Voltage supply HTG911H

POWER SUPPLY 24 V DC 2.5A 70°C. KNX system description The KNX system is a flexible, upwards compatible installation bus system (formerly EIB = European Installation Bus) for use in building systems technology. It is specially tailored to meet special requirements in terms of comfort, the ability to use space flexibly, the combination of central and distributed control, the intelligent linking of trades and systems, communication possibilities, environmental compatibility, energy and operating cost minimization as well as the functions of display, reporting, operation, monitoring and detection. Due to its decentralized structure, it enables building-specific operational management in residential and purpose-built buildings, regardless of the size of the plant. The availability of commercially available power distributors and installation sockets has a particularly beneficial effect. All bus nodes are connected via a bus cable (e.g. J-Y(St)Y 2x2x0.8) corresponding to the KNX guidelines (Konnex Association). Since the bus cable can be laid directly next to high-power cables according to DIN VDE 0100 the cable routing is greatly simplified. In contrast to public telecommunications systems, the bus system with all components must be treated as a high-current system. As in the case of high-voltage installations, the cable routing may be made in a line, star or tree form. A combination of the different cable routing is generally permitted. Two-wire wiring is provided with the wires of the preferred wires in red (for "+") and black (for "-"). The wires with the colors white and yellow serve as reserve. The nodes are supplied with the bus voltage via the bus cable (safety low voltage SELV 30 V DC). At the same time, it is used to transmit the information that is exchanged between the bus nodes. A terminating resistor is not required for the bus cable. The smallest unit in the KNX
