1. Description
The KNX-SA41 / KNX-SA24 module is an universal switch actuator, which makes it possible
to control electrical devices (lighting, ventilation).
The modules differ by the number of outputs, the KNX-SA41 having four and the
KNX-SA24 eight relay outputs (see “Electric diagram of relay outputs”).
load circuit terminals for connecting loads (2 terminals per channel).
green LEDs indicating the channel state. One channel state LED is assigned to each
channel:
ON –channel enabled,
OFF –channel disabled.
buttons to manually change the channel state. One ON/OFF button is assigned to each
channel.
The manual change of channel state is monitored by the module. The values of
communication objects responsible for storing information about the current state of
individual channels are systematically updated, according to the changes made.
The buttons are also used to restore the module factory default settings (see
“Restoring the module factory default settings”).
red LED –is ON when physical address is being set using the ETS program. Setting the
address may be activated manually, using the button on the enclosure, or remotely
from the ETS program.
programming button (used when setting the physical address).
terminal to connect KNX bus.
mains supply terminals.

1.1 Electric diagram of relay outputs
The KNX-SA41 and KNX-SA24 modules differ by the number of independent circuits and the
number of relays per each of these circuits. The KNX-SA41 has 4 independent circuits with 1
relay per circuit, while the KNX-SA24 has 2 independent circuits with 4 relays per circuit
(Fig. 2).
Information on what is the number of circuits and relays in the module is contained in
the module symbols (KNX-SA41/KNX-SA24). The first digit in the symbol means the
number of circuits in the module, and the second –the number of relays per one
circuit.
1.2 Enclosure
PCB of the KNX SA41 and KNX SA24 modules is mounted in enclosures, which have
identical shape and dimensions. The enclosures only differ by their panels for manual control
of channel state. In the figure 3, the enclosure dimensions are presented based on the
example of KNX-SA41 module. The module occupies 4 units on the DIN rail (35 mm).

2. Installation
Disconnect power before making any electrical connections.
The module is designed for indoor installation, in spaces with normal air humidity, e.g. in
distribution boxes on 35 mm DIN rail.
1. Mount the module on mounting rail.
2. Use the connecting terminal to connect KNX bus cable to the module.
3. Connect the loads to load circuit terminals.
4. Connect module power to N and L terminals.
All connections should be made in accordance with the wiring diagram for the given
module (see “Wiring diagram”).
5. Connect a computer running ETS program to the KNX bus and configure the module.
To configure the module, you will require a computer running the ETS program version
5.5 or newer, provided with USB or Ethernet (TCP/IP) connector. The SATEL ETS
application file, which can be downloaded from www.satel.eu/ets, must be imported
into the program.

3. Restoring the module factory default settings
1. Disconnect the module from KNX bus.
2. Power off the module.
3. Power on the module again.
4. Press simultaneously the four channel state control buttons situated on the module
enclosure (see “Description”). For the KNX-SA24 module, use the control buttons
grouped in the upper row of buttons (A,C,E,G) to reset memory. The indicator LEDs
situated above the buttons will go on.
5. Hold down the buttons until the indicator LEDs go off (about 10 seconds). The module will
restart with restored factory default settings.
6. Connect the module to KNX bus.
