087H3200

Product Description:

The 087H3200 from Danfoss is a compact controller made for the Danfoss Cables and Accessories lineup. Here the build is dense, not oversized, and the whole unit comes protected at IP41, which blocks small objects and light moisture in places like control panels or wall installations. Overall size checks in at 220 × 110 × 80 mm, measuring with the base. Major visibility comes from a bright graphical monochrome display showing 128 × 96 dots. With this many pixels, numbers and menus come up clear no matter the room light, and the backlight means no guessing when shadows land.

Turning to operation, things are made simple using the turn-push-dial, hooked into a menu-based system. Tuning settings or walking through screens avoids the mess of tricky button groups—spin, tap, and jump to the needed part fast, which makes setup or changing a value quick work. One hidden plus is the external sensor input for Pt1000 (ESM-10) sensors. This port lets users add precise temperature measurement, a solid utility inside HVAC zones or when tracking conditions in a room from the outside. Signals and power both run smoothly, as the supply connects through the reliable ECL 485 communication bus, tying right into other Danfoss controller setups that use the same network.

Inside every device, the data matters. Memory lands on EEPROM, so saved settings stand firm even if power drops or the lines get pulled by accident. For energy, the total use sticks low at 1 VA, so panels aren’t loaded heavy and standby loss stays minimal. More tough details: the storage temperature spreads from -40 to 70 °C, holding together whether shipped inside a freezing van or left in a hot storeroom. Fit is flexible too—there’s a mounting cut-out spec’d as 139 × 93 mm, letting this controller swap in without headache during upgrades.
