The Setra SRH30011D1RPNNMAAA is a factory-configured Setra Model SRH300 humidity and temperature transmitter, set up as a wall-mount unit with display, one sensor port, and a remote probe. Besides measuring relative humidity and temperature directly, the SRH300 also calculates related values like dew point, absolute humidity, and mixing ratio, so you don’t need a separate calculation step on the controller side.
In actual application, this unit outputs a 4-20mA analog signal, and the housing is rated IP65/NEMA4, so it holds up well even in washdown areas or humid mechanical rooms. From our experience, this is the kind of transmitter used in cleanrooms, labs, and climate-controlled storage where both the humidity reading and the temperature reading matter for process control, not just one or the other.
Setra also offers optional configuration accessories (SETRAPCA1 and SETRAPCA3) that let you set custom output scaling or do a one or two point field adjustment of the RH and temperature reading, which is handy if you need to recalibrate on site without sending the unit back.
Before we quote this, we would normally check the mounting type (wall, duct, or outdoor air), whether you need the remote probe or an integrated probe, the accuracy class you need, and whether analog or RS485 (BACnet/Modbus) output suits your system better. Hope this helps.
