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.
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)
•6 Safe +24 V DC/0.5 ms inputs (EN 61131-2; EN IEC 62061 und
EN ISO 13849)
•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.

3.5 Compatibility
INFORMATION
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.
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).
