Safety Automation Solution – BACHMANN SDO204 | SD0204 Safety Digital Output Module | MX Series
Where This Product Is Used
The BACHMANN SDO204 (SD0204) Safety Digital Output Module is purpose-built for safety-critical industrial environments where reliable, certified digital output control is non-negotiable. Typical deployment scenarios include:
- Wind Turbine Control Systems – Integrated into BACHMANN MX Series controllers for pitch control, brake actuation, and emergency stop circuits in onshore and offshore wind turbines.
- Industrial Safety PLCs – Used as a certified safety output stage in machine guarding, emergency shutdown (ESD), and safety instrumented systems (SIS).
- Process Automation – Deployed in oil & gas, chemical, and power generation plants requiring IEC 61508 / SIL2-compliant digital output channels.
- Renewable Energy SCADA – Acts as the final control element in safety loops monitored by SCADA and DCS platforms.
- Test & Validation Rigs – Used in HIL (Hardware-in-the-Loop) test benches for validating safety logic in automotive and aerospace applications.

Application-Specific FAQ
Q: Is the SDO204 compatible with BACHMANN MX200 controllers?
A: Yes. The SDO204 is fully compatible with the BACHMANN MX Series backplane, including MX200, MX213, and MX220 CPU modules.
Q: Can the SDO204 be used in SIL2 safety loops without an external safety relay?
A: In many architectures, yes. The SDO204 is TÜV-certified to SIL2 per IEC 61508, allowing direct connection to actuators in certified safety loops. Always verify with your functional safety engineer and the applicable BACHMANN safety manual.
Q: What is the difference between SDO204 and SD0204?
A: SDO204 and SD0204 refer to the same physical module. SD0204 is an alternate notation (using the digit zero instead of the letter O) commonly found in older documentation and procurement systems. Both designations are accepted when ordering.
Q: Do you provide a warranty?
A: Yes. Konmask offers a 90-day functional warranty on all tested modules. Extended warranty options are available upon request.
Q: Can you supply the BACHMANN SolutionCenter software license?
A: We can assist with sourcing BACHMANN software licenses. Contact us for availability and pricing.
