Technical specifications
Why choose SRO24M
Built for a defined industrial duty
Use SRO24M when the application calls for a true mechanical contact rather than a solid-state output. The relay combines a 6 A contact rating, AC/DC load capability, visible status indication and a replaceable plug-in format for industrial control panels.
240 VAC / 250 VDC nominal load
One relay type covers common industrial AC and DC circuits.
10 million mechanical operations
Published typical mechanical life for the relay mechanism.
Integrated status LED
Local indication helps commissioning and troubleshooting.
Application guidance
Use it where its strengths matter
Suitable applications
- General-purpose AC and DC load switching
- Applications requiring a true galvanically isolated mechanical contact
- Industrial panels using 24 VDC control voltage
- Replaceable relay assemblies with DIN-rail sockets or multi-channel bases
Check before selection
- The nominal coil voltage is 24 VDC; the absolute input range is 19–32 VDC.
- The 6 A contact rating must be checked against the actual load type and the datasheet derating curve.
- For DC loads, the datasheet specifies a 12 V / 100 mA minimum load point.
- Use a correctly rated fast fuse and confirm that the switching duty is suitable for an electromechanical contact.
Mechanical-contact option: SRO24M provides a true normally open AgSnO₂ contact for applications that specifically require electromechanical switching. For contactless high-frequency switching, compare the application with a Delcon solid-state output relay. See how Delcon technology works →

Frequently asked questions
SRO24M selection basics
Is SRO24M a solid-state relay?
No. SRO24M is an electromechanical output relay with one normally open AgSnO₂ contact.
Can it switch both AC and DC loads?
Yes. The datasheet gives nominal load voltages of 240 VAC and 250 VDC. The actual load must still be checked against the contact rating and derating curve.
What control voltage does it require?
The nominal coil voltage is 24 VDC, with an absolute input-voltage range of 19–32 VDC.
Which socket should be used?
Use MOS1GN for screw terminals or MOS1CCN for spring terminals. Compatible MB/MBS 8- and 16-channel mounting bases can also be used.
