Product Description:

The 084B4157 sits in the AK-CC55 Case Controllers line from Danfoss and brings a mix of practical controls with a straightforward design. Built for easy operation in supermarket cases or walk-in coolers, the unit features a simple front display for local adjustments on the spot. The supply voltage works in a range from 115 to 230 V AC at 50/60 Hz, so switching between electrical standards isn't a big issue. Inputs run six analog for all sorts of sensors, fitting right into any modern setup that demands more control options.

Outputs back up its flexibility, with six digital outs and support for AKV valve output type. The addition of MODBUS communication inside the controller means it can link up with larger automation systems smoothly. There are three digital inputs, which gives just enough triggers for things like door switches or alarm signals—never too little, never wasted. Wiring through screw terminals keeps everything simple and is useful when swaps or repairs happen fast.

With the built-in features locked down, the controller keeps to a reliable pace in environments where stability matters—think constant temperature or regular defrost cycles in food retail. The unit’s durability comes from steady power handling (only 5 VA drawn from the grid) and the protected enclosure doesn’t let dust or minor splashes knock it out. For extra options, some models support a LON RS485 comm card, making upgrades possible later on. Screw mounting keeps it easy to swap out during routine work, and the straightforward construction means no fuss in tight panels. This controller slides neatly into everyday setup routines but stands ready for advanced connections, saving both time and some headaches during installation or troubleshooting. With every sensor and relay slot mapped out, the 084B4157 manages cooling reliably, so goods stay fresh and systems keep moving.
