1-Wire Hub III DC, central power supply and distribution for the 1-Wire network with 24VDC input voltage. The 1-Wire Hub III DC is the central module for building a 1-Wire network. The 1-Wire Hub III DC supplies the 1-Wire network with 5V and 12V voltage and distributes the 1-Wire data line. 1-Wire Hub III DC can be ideally combined with a 1-Wire bus coupler (USB, Ethernet or serial) or 1-Wire controller. The input voltage of the 1-Wire Hub III DC is nominally 24VDC (18-36VDC) and is therefore especially suited for system environments with DC voltage supply, such as PLC controls. Equipment / Function: Central power supply of the 1-Wire network 1-Wire distribution for several bus sections LED display for power and 1-Wire activity Measurement function for the output voltages (voltage and current measurement for the 5V and 12V output)Note: The device has no repeater function for the 1-Wire data signal, which means that the device does not increase the possible network size.Note: The device has no repeater function for the 1-Wire data signal, which means that the device does not increase the possible network size.

Active termination for 1-Wire networks In a 1-Wire network, the 1-Wire Term 1 provides a defined termination at the end of the 1-Wire network, thus ensuring a stable and professional 1-Wire network. The 1-Wire Term 1 is therefore a basic component of every 1-Wire network. The module contains a passive and active terminating resistor and a signaling of bus activity. The active termination (1-Wire Term 1) is highly recommended to increase the maximum line length and improve the system stability of the 1-Wire network, especially for long 1-Wire lines and for a star or tree topology setup. In a 1-Wire network, up to 3 1-Wire Term 1 modules can be connected. The 1-Wire Term 1 is very compact and can be ideally installed in a flush-mounted box. Function Termination for 1-Wire networks, active Channel 1 channel Operating voltage 5VDC, max. 5mA Display 2, LED for power and 1-Wire data Miscellaneous Integrated overvoltage and reverse polarity protection Dimensions 40x40x25mm (LxWxH) Scope of delivery Module and operating instructions Integration into 1-Wire network The 1-Wire Term 1 module is mounted at the end of a 1-Wire network cable. If the 1-Wire network is star-shaped, i.e. with several 1-Wire cable sections, a 1-Wire Term 1 module should be connected to each end. You should not use more than three 1-Wire Term 1 modules in a 1-Wire network. Linear Topology The structure corresponds to the linear topology with the difference that the slaves are connected to the main line via cables with a length of more than 3m (branch, stub).   Star or tree topology The network is divided into several large strings at or near the 1-Wire bus coupler / 1-Wire controller /1-Wire hub (bus master). Sensors and actuators (e.g. switching modules) are connected at the end or along the respective string.   For more information, please refer to the operating instructions under Links/Downloads.
