Switch, switch-dim, switch-change I/P 4x

Input module with four addressable inputs for integrating a conventional light/window/blinds/screen momentary-action switch, switching/changeover switch/momentary-action switch, motion detector, time switch or other contact-maker in a bus-controlled lighting and room management system. Depending on the addressing of an input, users can operate all the actuators in a room, or one actuator group in the room. Can be used as: • Switching input: short press on one of the connected momentary-action switches toggles between the two scenes "Absent 0" and "Present 1" • Switching-dimming input: short press on a connected momentary-action switch toggles between the two scenes "Absent 0" and "Present 1". Long press on the switch: the lighting is dimmed alternately up and down. • Switching-changeover input: closing a contact-maker connected to the "T1 / T2" inputs runs the "Present 1" scene, while opening a contact-maker connected to the "T3 / T4" inputs runs the "Absent 0" scene. Connect a continuous contact-maker to the linked "ON" and "OFF" terminals. Each module input has two terminals: "ON" and "OFF". • Blinds and screen input: blinds/screens in the room can be raised by pressing a momentary-action switch connected to the "T1/T2" inputs, and lowered by pressing a momentary-action switch connected to the "T<" inputs. Press and hold (> 3s): blinds/screens move into the limit of travel or working position. Each module has two "T>" and "T<" inputs. • Window input: windows in the room can be opened by pressing a momentary-action switch connected to the "T>" inputs, and closed by pressing a momentary-action switch connected to the "T<" inputs. Press and hold (> 3s): window moves into limit of travel. Each module has two "T>" and "T<" inputs. Power is supplied via the DALI control line (no mains connection) with a current consumption of 4mA (2 DALI loads). The DALI input can withstand an external voltage of 230/240V. The bus line can be screw-connected to the module input. Installed in flush socket (Ø 53mm, height 15mm) fitted behind switch and made of halogen-free flame-retardant polycarbonate, transparent. The contact-makers must have an isolated switching contact designed for at least 15VDC and must be suitable for connecting to the input lines of the module. Dimensions 41.2 x 28.2 mm, weight: 0.03 kg
