Switch Actuators SA/S
x.6.1.1, 6 A, MDRC
SA/S 12.6.1.1
Switch Actuators SA/S
x.6.1.1 6 A are
modular installation devices in Pro
M
design for installation in the distribution
board. They are suitable for switching
resistive, inductive and capacitive loads.
The actuators can switch up to
12 independent electrical loads via
floating contacts. The outputs are
connected using screw terminals in
groups of two contacts for SA/S 8.6.1.1
and SA/S 12.6.1.1. SA/S 4.6.1.1 has one
terminal per output for power feed. Each
output is controlled separately via KNX,
regardless of the variant.
The device does not require an
additional power supply and is ready for
immediate use after the bus voltage
has been applied. The Switch Actuator
is parameterized via ETS. Connection
to KNX is implemented using the bus
connection terminal on the front.
