S-DIAS Safety Digital Input Module SDI 101
The S-DIAS SDI 101 Safety digital input module has the safety integrity
level SIL3 or SIL CL 3 (EN / IEC 62061) or Performancelevel e (PL e)
(EN ISO 13849-1/-2).
The SDI 101 has:
• 10 Safe inputs (EN 61131-2; EN/IEC 62061 and EN ISO 13849-
1/-2)
• Doubled clock output signal (short-circuit proof)
The safety inputs are used for reading 10 actuator signals (Emergency
Stop, confirmation button etc.).
To test inputs and detect cross circuits (e.g. Emergency Stop), the
SDI 101 has two non-safe signal outputs, TA and TB.
The safety-related SDI 101 is ideal for use in systems with optional
modules and interface variables according to Safety System Handbook,
see homepage1.
To use the SDI 101 in an application, a Safety CPU module that regulates
the synchronized communication with the safety modules using safe bus
telegrams is also required. This also includes
• Processing the safe application and
• The distribution of configuration data to remote safety modules.

SIL 3
(1)
DC is "high" according to table 5 and the corresponding note EN / ISO 13849. In
combination with the high MTTFD value and the good PFHD value, the performance level
according to table K.1 is PLd.
Reason for SIL 3 with single-channel use:
Because the high SFF value is greater than 99 %, SIL 3 can be accepted with a hardware
tolerance (HFT) of 0 according to EN 62061.

2.4 Compatibility
Compatibility
For compatibility of the S-DIAS Safety modules, see section
"Compatibility of S-DIAS Safety Modules" in the system
handbook.
Test Signals for Cross-Circuit Detection
The module sends pulses in cyclic time intervals to detect a crossed circuit in
the outputs. When selecting the actuators, keep in mind that these pulses do
not activate the actuators or trigger any diagnostic messages. The pulse
signals cannot be deactivated or configured.
Les tests pour la détection de courts-circuits
Le module envoie cycliquement des impulsions afin de détecter un court-circuit
sur les sorties. En choisissant les actionneurs assurez-vous que ces
impulsions ne provoquent ni une commutation d'un actionneur ni l’apparition
d’un message de diagnostic. Les impulsions ne peuvent être ni désactivées ni
configurées.
Cross-Circuit Detection
It is important to keep in mind that the cross-circuit detection only functions
correctly when it is configured and wired correctly. This applies equally to inand outputs.
Détection de courts-circuits
Il est important de noter que la détection de courts-circuits dans le contexte
des fonctionnalités de sécurité ne fonctionne que si elle a été correctement
câblée et configurée. Cela vaut aussi bien pour les entrées que pour les
sorties.

Miscellaneous
short-circuit proof
The clock outputs A and B are generated once internally and are wired in parallel to
the connectors. A direct cross-circuit of Clock A and/or B of a connector therefore
results in cross-circuit detection in all channels.
When using the digital inputs with the clock outputs for cross-fault detection for long
cable lengths, make sure that the cable capacitance from the clock output to the
digital input does not exceed a value of 100 nF and that the cable resistance does not
exceed a value of 250 Ω, so that the cross-fault detection does not detect a wiring
error with proper wiring.

6.2 Note
The input filters, which suppress noise signals, allow operation in harsh environmental
conditions. A careful wiring method is also recommended to ensure error-free function.
The following installation guidelines should be observed:
• Avoid parallel connections between input lines and load-bearing circuits.
• Protective circuits for all relays (RC networks or free-wheeling diodes)
• Correct wiring to ground
The ground bus should be connected to the control cabinet when possible!
Si possible la terre doit être connectée à l'armoire de commande!
The wiring and assembly must be performed when no voltage is applied!
Le câblage et l'installation ne doivent être effectués que sur un système hors
tension !
IMPORTANT:
The S-DIAS module CANNOT be connected or disconnected while voltage is applied!
IMPORTANT:
Le module S-Dias NE PEUT PAS être inséré ou retiré sous tension.

7 Mounting
The S-DIAS modules are designed for installation into the control cabinet. To mount the
modules a DIN-rail is required. The DIN rail must establish a conductive connection with the
back wall of the control cabinet. The individual S-DIAS modules are mounted on the DIN rail
as a block and secured with latches. The modules must be mounted horizontally (module
label up) with sufficient clearance between the ventilation slots of the S-DIAS module blocks
and nearby components and/or the control cabinet wall. This is necessary for optimal
cooling and air circulation, so that proper function up to the maximum operating
temperature is ensured.

8 Supported Cycle Times
The SDI 101 supports different cycle times. If variable sample points are deactivated, the
IOs are updated with 4 kHz at cycle times of 250 µs to 32 ms. If the cycle time is lower than
250 µs, the IOs are updated with 3 kHz and PDO data are transmitted in a millisecond
