22154488 LM-4AWS Input module with four independently addressable inputs for integrating conventional PIR sensors 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: Closing and opening a contact-maker connected to the input terminal runs the "Present" or "Absent" scene according to a defined characteristic. Module designed for local and central automation. For local automation, the "Absent" scene runs with a delay time of 10 minutes and a cross-fade period of one minute. For central automation, the user can set the delay time and cross-fade period to suit. Module input voltage 230 V AC, 50/60 Hz, installed on 35 mm DIN rail to EN50022, width 4 HP (1 HP = 17.5 mm), made of halogen-free, flame-retardant polycarbonate, light grey. Bus and mains cable can be screwed to device inputs. PIR sensors can be screw-connected as standard 230 V devices to the inputs of the module.
