S-DIAS Safety Analog-Input Current Module SAI 041
The S-DIAS safety analog input module provides the values of
four analog current inputs from the Safe CPU (Safety CPU). The
analog inputs can also be read by the functional control CPU via
the S-DIAS bus from the safety CPU. The four current inputs
have an input range of 4-20 mA with a resolution of 16 bits. A 24
V sensor supply is provided for the analog inputs, which must be
powered externally. The external 24 V supply for the analog
inputs is monitored for Over- and under voltage.
Safe evaluation of the analog inputs is ensured by two
independent diversitary evaluations with mutual monitoring.
The safety functions of the component meet the requirements
•for two-channel use
according to SIL 3 in compliance with EN 62061 and PL e,Cat. 4 in accordance with
EN ISO 13849-1/-2.
as well as
•for single-channel use,
the requirements for to SIL 3 in compliance with EN 62061 and PL e,Cat. 3 in
accordance with EN ISO 13849-1/-2.

1 Basic Safety Guidelines
1.1 General Information on Safety
If the Safety guidelines are not followed, danger to personnel can result, which could then
lead to serious injury or in worst cases, death. In less serious cases, systems and equipment
can be damaged.
The following symbols identify the individual risks as well as the degree of seriousness; their
respective meanings are briefly explained below. You should therefore familiarize yourself
with the Safety symbols and their meanings to prevent dangers and risks.
DANGER
DANGER
Identifies an immediate danger with high risk, which
will lead to immediate death or serious injury if not
avoided.
Identifie un danger immédiat à haut risque, qui
entraînera immédiatement la mort ou des blessures
graves s'il n'est pas évité.
WARNING
WARNING
Identifies a possible danger with a mid-level risk, which
can lead to death or (serious) injury if not avoided.
Indique un danger possible d’un risque moyen de
décès ou de (graves) blessures si les consignes de
sécurité ne sont pas respectées.
CAUTION
CAUTION
Identifies a low-risk danger, which can lead to injury or
property damage if not avoided.
Indique un danger avec un niveau de risque faible des
blessures légères ou des dommages matériels si les
consignes de sécurité ne sont pas respectées.
