KNX switching actuator 1-gang 16 A with binary input, 3-gang

Features

Inputs

• Depending on the ETS parameterisation in the application for switches, buttons or contacts, inputs 1 and 2 either act internally on the relay output or separately on the KNX. Input 3 always acts on the KNX.
• Functions for the inputs when acting on the KNX (switching, dimming, blind, value transmitter, scene auxiliary unit, 2-channel operation, controller auxiliary unit, no function).
• Switching: Command for closing and opening of the contact adjustable (no reaction, ON, OFF, TOGGLE).
• Dimming: Dimming of brightness and/or colour temperature. Command for closing the contact, time between switching and dimming, dimming in different steps, telegram repetition in case of long signal at the input, and sending of a stop telegram at the end of the dimming process all configurable.
• Blinds: Command for closing the contact and the operating concept can be parameterised. Times for short and long signal at input and slat adjustment are adjustable.
• Value transmitter: Functionality as 1-byte, 2-byte, 3-byte or 6-byte value transmitter including colour temperature and colour value transmitter possible. Individually configurable values. Value adjustment is optionally possible with a long signal at the input (not with the 6-byte value transmitter).
• Scene auxiliary unit: Mode of operation (with or without memory function) and the scene number are adjustable.
• 2-channel operation: When the contact at the input closes, up to two telegrams can be sent out on the KNX. Operating concept adjustable (only channel 1 or channel 2/both channels). The mode of operation of the channels (1-bit, 1-byte, 2-byte, 3-byte, 6-byte) can be configured separately.
• Controller auxiliary unit: Mode of operation (operating mode switching, forced operating mode switching, presence function and target value adjustment) configurable.
• Disabling of all or individual inputs via a 1-bit object possible. Polarity of the blocking object, behaviour at the beginning and end of blocking, and behaviour during an active blocking can be adjusted.

Logic functions

• The device has 8 internal logic functions.
• Logic gate (AND, OR, exclusive AND, exclusive OR, each with up to 4 inputs).
• 1-bit to 1-byte converter with input filter, blocking object and specification of output values.
• Blocking element with filter and time functions and blocking object.
• Comparator for values with 9 different input data formats and many comparison operations.
• Limit value switch with hysteresis with upper and lower threshold values for 9 different input data formats. Including specification of the 1-bit output values.
• The logic functions have their own KNX communication objects and can process telegrams from the actuator or other bus devices.
• Switching electrical consumers via a relay contact.
• Device has three inputs with a common reference potential.
• Reading in switching states of installation switches or push buttons and other zero-voltage contacts at inputs 1 to 3.
• Signal analysis of dew and leakage sensors (see accessories) at inputs 1 to 3.
• Recording of temperature values via remote sensors (see accessories) at input 3.
• Up to 8 independent logic functions for implementing simple or complex logical operations.
• Actively transmitting feedback or status messages can be delayed after a bus voltage recovery or ETS programming mode.
• Bistable relay.

Switching functions

• NO contact or NC contact operation.
• Central switching function via up to 6 switch objects (ON, OFF, permanently ON, permanently OFF).
• Feedback on switching: Active or passive feedback function.
• Reaction in case of bus voltage failure or bus voltage recovery can be set following an ETS programming process.
• Logical linking function.
• Block function or forced setting function can be parameterised.
• Extended blocking function with acknowledgement option.
• Time functions (switch-on and switch-off delay, staircase light function – also with advance warning function).
• Can be integrated in the light scenes: Up to 64 internal scenes can be parameterised.
• Scene memory function: Additional visual feedback.
• Extended scene retrieval (toggling of scenes).
• Elapsed operating time meter can be activated.
• Input monitoring for cyclic updating of the switching object with safety position.
