Why do some priducts qualify for forum and email support while others don't?

Some products show forum and email support while others don’t. Why?

The PR33-26 and PR33-49 are very similar 4-20mA current loop transmitters, the difference being that one supplies loop power. Yet one has support and the other doesn’t.

PR33-26 shows forum and email support.

This product qualifies for:

  • Forum Support (fastest)
  • Direct Email Support

PR33-49

does not sjhow forum and email support.

ALL I2C products fall under forum support, no exception
