The universal foot of the Weidmüller relay
modules allow them to be assembled on
TS 32, TS 35 x 7.5 and TS 35 x 15
mounting rails in accordance with
European standards EN 50 035 and
EN 50 022.
An LED status indicator in the coil of the
relay coupler indicates the relay switching
status.

resistance to burn-off
Contact material
The all-round capability of Weidmüller relay
modules is achieved by the choice of the
contact material.
The contact is responsible for both the
reliable transmission of the control signals
and for switching power contactors.
Weidmüller uses gold-plated or gold-
flashed AgNi contacts for most applica-
tions. Gold-plated contacts permit
the switching of the low-power applica-
tions up to 40 µW with a gold-plating
thicker than 2 µm. For switching higher
ratings we use AgSnO2 or AgCdO con-
tacts (RS 31).
