S-DIAS Safety Digital Mixed Module SDM 081
The S-DIAS Safety SDM 081 digital mixed module has the safety integrity level
SIL3 in accordance with EN / IEC 62061 or Performancelevel e (PL e) in
accordance with EN ISO 13849-1/-2.
The SDM 081 has:
•2 Safe +24 V outputs with a maximum of 2 A per output
(EN 61131-2; EN / IEC 62061 und EN ISO 13849-1/-2)
•6 Safe +24 V DC/0.5 ms inputs (EN 61131-2; EN / IEC 62061 und
EN ISO 13849-1/-2)
•Redundant output signal (short-circuit proof)
The safe outputs are used for the safety-oriented output of two actuator
signals to, for example, control relays, valves, etc.
The safety inputs are used for reading six actuator signals (Emergency Stop,
confirmation button etc.). To test inputs and detect cross circuits (e.g.
Emergency Stop), the SDM 081 has two non-safe signal outputs, A and B.
The safety-related SDM 081 is ideal for use in systems with optional modules
and interface variables according to Safety System Handbook, see
homepage
1
.
To use the Safety digital input module in an application, the SDM 081 also
requires a Safety CPU module that regulates the synchronized communication with the safety
modules using safe bus telegrams. This also includes
•processing the safe application and
•the distribution of configuration data to remote safety modules.

(1) According to Table 5 and the corresponding notes EN / ISO 13849 in the "high" range.
In combination with the high MTTFDvalue and the good PFHDvalue, DC is the performance
level PLd according to table K.1.
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.
Contact Short 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 in- and
outputs.
It must also be considered that the cross-circuit detection only works between
adjacent inputs. Cross circuits between adjacent inputs must be prevented via
constructive measures (e.g. separate wiring, insulated cables).
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.
Il faut également tenir compte du fait que la détection de circuits croisés ne
fonctionne qu'entre des entrées adjacentes. Les circuits croisés entre des
entrées adjacentes doivent être empêchés par des mesures constructives (par
exemple, câblage séparé, câbles isolés).

short-circuit proof
(2) With increased ambient temperature >55 °C the maximum permissible supply voltage is
reduced from 30 V to 28.8 V.
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.
