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

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

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

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.
