Can I use this converter for a 12V PLC and I/O load in an industrial control cabinet?

Yes, it can fit a 12V constant-voltage control load when the source is within 19-36VAC. The output is rated for up to 16.7A and 200.4W, so the combined PLC, I/O, and accessory load needs to stay within those limits.

Is this a good choice for powering a 12V HMI or operator interface from a higher input range?

It is suitable for 12V HMI or operator interface equipment that needs constant-voltage power from a 19-36VAC input source. The available output is 12V at up to 16.7A, with 200.4W total capacity.

Can this run a 12V embedded computer or industrial edge device?

It can support a 12V embedded or edge system as long as the total draw remains at or below 16.7A and 200.4W. The unit is a constant-voltage converter, which is the right operating mode for electronics designed for a fixed 12V supply.

Is the SD-200B-24 intended for outdoor or washdown environments?

The listed operating temperature is -20°C to +60°C, but no IP rating is provided in the specs. That means it is better suited to protected indoor enclosures rather than open outdoor or washdown exposure.

How does the SD-200B-24 compare with the other SD-200B models?

In the SD-200B group shown here, SD-200B-12 is listed at 170W, 5V, 34A; SD-200B-24 is listed at 200.4W, 12V, 16.7A; SD-200B-48 is listed at 201.6W, 24V, 8.4A; and SD-200B-5 is listed at 201.6W, 48V, 4.2A. All share the same 19-36VAC input family and constant-voltage operation, so the main differences are output voltage, current, and wattage.
