Possible to create the highest level safety system
Compatible up to control
category 4
Installation time and labor can be saved due to the usage of
detachable terminal blocks
Control category 4 compatible
with an SF4B series / SF4B-C
series / SF4C series combination
and control category 2 compatible
with an SF2B series / SF2C
series combination.
As wiring can be performed with the terminal blocks
removed, it is not necessary to detach the controller
from the control panel when performing maintenance,
thus reducing the number of installation procedures
required. Also, when replacing the relay units,
you simply insert new terminals without having to
manipulate the wiring.
A connecting terminal blocks are not needed
As SF-AC incorporates a
power supply terminals and
synchronization lines terminals for
the light curtain, so terminal blocks
are not required.

Unexpected start due to start-switch welding prevented
Incorporates a 2-channel auxiliary output
The unit is equipped with a trailing edge switching
function, which causes an ON signal to be sent when the
start switch signal is falling. This prevents unexpected
starting which can occur if the start switch gets welded.
SF-AC incorporates both an auxiliary output that
operates together with the light curtain’s control output
(OSSD), and an alarm output that functions together with
the light curtain’s auxiliary output (non-safety output).
These features allow for monitoring of light curtain
activity.
