Symmetrical construction with centered chain outlet. For the convenient motorised opening and closing of bottom hung-, top hung-, parallel opening-, and trapezoidal windows in the facade, as well as for roof windows. Useable for daily ventilation mode. Compatible to D+H locking drives. Performance features: Integrated Advanced Communication Bus interface (ACB) with open Modbus RTU protocol. High-precise motor- and synchron electronic for parallel run for up to 8 drives. Connection of up to 4 lock drives. Corrosion-protected, hardened, rigid backing steel chain, maintenance free by lifetime lubrication. Special chain stabilisation. Active and passive locking edge protection. Various adjustable drive parameters (stroke, force, speed). Gasket protection thanks to the automatic relief of pressure on window gasket after a closing process. Easy installation thanks to polarity reversal protection connector. Individual parameterising via D+H software SCS. Low operation noises. Direct integration of drive by open Modbus RTU bus-communication via Advanced Communication Bus (ACB) for the building automation, e.g. in BMS (building management system) with following features: - Exact position operating (relative values, in 1 % steps) - Creation of virtual groups at one output - OPEN and CLOSED-indication (incl. lock drive)/ group signal - Monitoring of connected drives - Diagnosis and configuration directly from the control panel/BMS - Status monitoring of motor - Modbus protocol "ACB planning manual" as download link on D+H´s website - Max. 32 ACB-bus-participants at Modbus RTU Technical data: Supply: 24 V DC / ±20 % / 0.35 A Duty cycle: 30 % (ON: 3 min. / OFF: 7 min.)
