1 General
KNX systems provide an attractive solution that meets the most demanding residential, commercial and
public buildings requirements. High living standards, comfort and safety can be easily combined with cost-
effectiveness and environmental awareness using KNX bus systems from ABB. KNX products cover the
entire range of buildings applications, from illumination and blind control to heating, ventilation, energy
management, security and surveillance. These requirements can be met cost-effectively with minimal
planning and installation effort using the ABB KNX. Furthermore, flexible room usage and continuous
adaptation to changing requirements are simple to implement. SA/S Switch Actuators fulfill individual
requirements in industrial, commercial and public buildings as well as in the private sector for controlling
switchable loads, e.g.:
•Illumination
•Heating control
•Signaling equipment
Certain types of Switch Actuator can also detect and monitor load current via a threshold value function.
Based on the load current detected, responses can be triggered via KNX and the load can be switched off
directly or switched via KNX.

1.1.1 Structure of the product manual
All parameters are described in section 3.
Please note
This product manual describes all the current 2/4/8 and 12-fold Switch Actuators. However, as the
functions for all outputs are identical, only the functions of output A will be described.
Where information in the product manual refers to all outputs, the description output A...X is used. 2-fold
corresponds to outputs A...B, 4-fold corresponds to outputs A...D, 8-fold corresponds to outputs A...H
and 12-fold corresponds to outputs A...L.
Variants with current detection feature an additional parameter page as well as additional
communication objects for this function.

1.2 Product and functional overview
SA/S
12.16.6.1
ABB i-bus®KNX SA/S Switch Actuators are modular installation devices with module widths of
2/4/8/12 units in ProMdesign for installation in a distribution board.
Connection to the ABB i-bus®is established via a bus connection terminal on the front.
The Switch Actuators require no auxiliary voltage.
The assignment of the physical address as well as the parameterization is carried out with
Engineering Tool Software (ETS), version ETS2 V1.3a or higher. If using ETS3 or ETS4 you
will need to import the corresponding application program.
Please note
The illustrations of the parameter windows in this manual correspond to the ETS3 parameter
windows. The user program is optimized for ETS3.
In ETS2 the parameter page for any parameter being used may split automatically.
The Switch Actuators can switch 2 to 12 independent electrical AC or three-phase loads via
KNX with floating contacts. With SA/S x.16.6.1 types it is possible to detect the load current for
each output. The outputs of the 6 A, 10 A, 16 A and 16/20 A Switch Actuators can be switched
on and off manually.
Switch Actuators SA/S x.16.6.1 and SA/S 12.16.5.1, which have the highest switching capacity
(C-load), are particularly well-suited for switching loads with high peak inrush currents, e.g.
lighting equipment with compensation capacitors or fluorescent lamp loads (AX) to EN 60 669.
The following functions can be set individually for each output:
•Time and ON/OFF delay functions
•Staircase lighting function with warning and modifiable staircase lighting time
•Recall of scenes/presets via 8/1 bit commands
•Logical functions AND, OR, XOR, GATE function
•Status messages
•Forced operation and safety functions
•Response to threshold values
•Control of electro-thermal valve drives
•Selection of the default state on bus voltage failure and recovery
•Output inversion

On Switch Actuators with current detection, SA/S x.16.6.1, each output also features the load current
detection function with parameterizable response to two current threshold values. The current value can
be sent via the bus. Individual outputs in the Switch Actuators can be copied or exchanged to minimize
programming work.
The SA/S x.16.6.1 and SA/S x.16.5.1 are suitable for rated currents up to 20 A and have C-load switching
capacity.

Please note
ETS and the current version of the device application program are required for programming.
The current application program is available for download at www.abb.com/knx. After import into ETS,
it is available in ETS under ABB/Output/Binary output xf 10A/…* (x = 2, 4, 8 or 12).
The device does not support the locking function of a KNX device in ETS. If you inhibit access to all of
the project devices by using a BCU code, it has no effect on this device.
Data can still be read and programmed.
