D+H | Source: www.dh-partner.com 12.12.2025 ACB chain drive - freely configurable - VCD-0204-1-ACB 24 V DC / Special production according to customer requirements Electromotive drive unit with Modbus RTU interface for surfaced mounting at the window profile. 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 Extension functions: Option "CP" - Customized drive function programming, e.g. operation speed, force and stroke Option "HP" - Stroke programming Option "VP" - Signal programming for connection with D+H BSY+ locking drives Option "DS" - Loop-through option enables connection with D+H locking drives and open bus communication via ACB Option "LS" - Low-speed programming in CLOSE direction 5 mm/s Option "AS2" - Acoustic signal according to protection class 2 MaschRL/42/EG Option "AS3" - Acoustic signal according to protection class 3 MaschRL/42/EG Option "SKS" - Direct connection of an anti-pitch strip or an optical sensor for closing edge monitoring at the drive possible Option "special colour" - Colour coating for perfect integration into façade optics according to RAL, DB, NCS Technical data: Supply: 24 V DC / ±20 % / 0.35 A Duty cycle: 30 % (ON: 3 min. / OFF: 7 min.)
