Product Description:
The 084B8040 controller from Danfoss is built as part of the Electronic Climate Controllers lineup. This device works with a supply voltage of 24 V AC/DC ±15% and runs steady at 50/60 Hz. Weight comes in at 300 g, so mounting isn’t a hassle, even in areas where there’s only tight access. The IP20 enclosure rating gives it basic protection, aimed mostly at indoor spots that stay pretty clean. Power draw measures 5 VA for the controller itself, which helps with efficient setups where there are several devices running together.
Connections and control signals are straightforward. Two Pt 1000 Ω sensor inputs allow for reliable temperature readings, which is critical in HVAC or industrial rooms that need constant monitoring. As for input types, signals get accepted in either 4-20 mA or 0-20 mA (current mode) and 0-10 V or 1-5 V (voltage mode). There’s also a RS-485 Modbus line, making remote adjustments or real-time checks possible from a distance. Output to the stepper motor ranges from 30-300 mA RMS switching, and alarm events have a SPDT relay with a max of 24 V, up to 1 A resistive, so status changes are easy to track or connect with external indicators if needed.
Operation covers a fair range: workable environments can go from 0 to +55°C routinely, with transport conditions staying safe down to -40°C and up as high as +70°C. This all helps installations in places with big temperature swings, like warehouses, greenhouses, or shops with on-off heating cycles. The compact layout, plus dual sensors and real-time Modbus link, lands well for plant managers or system installers who care about dependable climate management but don’t want a complicated setup. Small size, flexible input options, and solid output specs give this Danfoss controller a strong fit in busy, temperature-sensitive buildings.
