Three−row connector socket from connector set type
SEA−KL−SAC10/30
Two rows of the three−row connector socket are intended as
distributor boards for the sensor supply. These rows are each
connected internally. The upper row (blue push buttons) is
intended for the 0 V distributor, the centre row (red push but
tons) is intended for the 24 V distributor. The relevant voltage
must be supplied with the aid of an external bridge from ter
minals + and (lower row).
