Installation examples
The PNP output is internally con-
nected to the +24 VCC. On termi-
nal 34 is available the collector of
the PNP transistor.
Connect to the 34 terminal an
external resistive load with R≥2400
Ohm (see fig. 3).
Connect the ground of the PNP
external circuit to:
• A2 terminal, if the safety relay is
powered with 24 Vdc supply;
• S12 (internal ground) terminal if
the relay is powered with an AC
supply.
WARNING
√
Please, note the maximum
length of the cables!
