Can I use this converter for a 24V PLC, relay, and sensor circuit in automation equipment?

Yes, it can fit a 24V constant-voltage load when the source is within 19-36VAC. The output is rated at up to 8.4A and 201.6W, so the total PLC, relay, and sensor demand needs to stay inside that range.

Will this work for a 24V HMI or industrial touchscreen system?

It can support a 24V HMI or touchscreen system that expects constant-voltage power. This model provides 24V output up to 8.4A, with 201.6W total available power.

Is this suitable for a 24V embedded controller or communications device?

It is appropriate for 24V embedded or communications hardware if the equipment uses a fixed 24V input and the load does not exceed 8.4A or 201.6W. The 19-36VAC input range also helps when the upstream source varies within that span.

Can this be used in a cold or hot indoor equipment enclosure?

The specified operating temperature range is -20°C to +60°C, so it is intended to operate across a fairly wide enclosure temperature range. Because no IP rating is listed, the safer fit is a protected indoor enclosure rather than direct outdoor exposure.

What are the differences between the SD-200B-48 and the other SD-200B versions?

The SD-200B variants listed here are SD-200B-12 at 170W, 5V, 34A; SD-200B-24 at 200.4W, 12V, 16.7A; SD-200B-48 at 201.6W, 24V, 8.4A; and SD-200B-5 at 201.6W, 48V, 4.2A. That means the selection is mainly about matching the required output voltage and current while staying within the same 19-36VAC input family.
