Lighting ControlsAccessoriesSelectionDescription of devicesAll devices described here are interconnected via 18 AWG solid copper twisted pair or via a communication bus on the DIN railsincorporated into the panels.Output (relay) Device (5WG1512-1CB01): Block of 8 277 V,20 amp, relays with timers,visual indication and manualoverride capability.Input Device (5WG1 261-1CB01): Block of 4 digitalinputs. It can take inputsfrom a set of dry contacts(maintained or momentary).Inputs requires 24 volt suppliedby the power supply.Sixteen Control Channels TimeClock (5WG1 373-5EY01): It has16 control channel. Each channelcan be seen by the system as aninput. This device can beprogrammed with up to 500different schedules, automaticday light saving time and 10 years battery back up. The firstfour control channels can be programmed as astronomicaltime clock. This feature allows to control the outside lightsbased on date and geographical location, rather than with anoutdoor light level sensor.RS232 Interface (5WG1 148-1AB04: It allows the user toconfigure the panel on site via aDB9 serial cable. Configuration isdone with the software suppliedfree of charge with every order.11 LIGHTINGCONTROLSPower Supply (5WG1 123-1CB01): Input 120 V, 50/60 HZ.One per panel. It suppliesvoltage for communications andfor the inputs.Choke (5WG1 120-1AB01): It ismounted next to the powersupply. The choke prevents thepower-supply 5WG1 123-1CB01from short-circuiting the data onthe bus line. It picks up thepower from the two outerprinted conductors and feeds it via inductors to the two innerprinted conductors.Four Control Channels TimeClock (5WG1 372-5EY01): It hasfour control channels; eachchannel can be seen by thesystem as an input. This devicecan be programmed with up to322 different schedules,automatic day light saving time and 10 years battery back up.IP Interface (5WG1 148-1AB21):It allows connection to the user’sLAN for control and monitoring ofthe system. Optional ComBridgeStudio software is required for LANconnectivity. It can be configured forfixed IP address and also for DHCP.Outdoor Ambient Light Sensor(5WG1 P254-3EY01): Used tocontrol outdoor lights such asparking lot, signs, drive throughwindow. Three light levelthresholds (100 Fc, 50 Fc and 20Fc) are pre-programmed into thedevice. This is also a temperature sensor. Outsidetemperature can be read when the optional ComBridge StudioLAN software is used.Motion Sensor (5WG1 255-2AB11): Detects motion tocommand light to turn ON. Eachmotion sensor require buscoupling unit 5WG1 114-2CB02.Siemens Power Distribution & Control, SPEEDFAX 2007-2008 Product Catalog 11-5
