■ Overview
Contact modules and LED modules
The contact modules are fitted with slow-action contacts (NO
contacts or NC contacts). These ensure a high switching reliabil-
ity even with small voltages and currents, such as 5 V/1 mA.
They are suitable for use in electronic systems as well as
conventional controls. The contact pieces of the NC contacts are
positively driven.
Only LED modules with permanently integrated LEDs are
available for illumination.
Contact modules and LED modules bear terminal designations
acc. to EN 50013.
Mounting the modules
With SIRIUS ACT, the modules are mounted on the holder with-
out any further accessories. Holders in plastic or metal versions
are available for mounting three modules.
Connection methods
The modules are available with:
• Screw terminals
• Spring-type terminals or
• Solder pin connections (0.8 mm × 0.8 mm solder pins)
for assembly on printed circuit boards
■ Selection and ordering data
1)
The contact module has 1 NO internal contact + 1 NC internal contact.
The NO contact is connected in series with the NC contact and brought
out at terminal 1-2. When the module is snapped onto the holder, the
NO contact closes. It opens when the module is detached from the holder
again (the NC contact remains closed). The NC contact opens when the
EMERGENCY STOP device is actuated (the NO contact remains closed).
The contact is closed only when both the NC and NO contacts are closed.
Unsuitable for mounting in 3SU18 enclosure.
Positive opening according to IEC 60947-5-1, Annex K.
Can be used with 3SK11 safety relays or the 3RK3 Modular Safety System,
see page see page 11/1 onwards.
