Rittal 3118000 Hygrostat, 24-250V DIN Rail Mount Condensation Control

The Rittal 3118000 Hygrostat activates the heater and/or fan when a preset relative humidity inside the enclosure is exceeded, raising the relative humidity above the dew point to prevent condensation on assemblies and electronic components. Rated for 24 V - 250 V, 1~ AC and 24 - 48 V (DC) operation, this compact enclosure accessory mounts on a vertical or horizontal 35 mm support rail to EN 50 022 or snap-fastens directly into the enclosure section or mounting plate using the supplied adapter, making it well suited for control cabinets, panelboards, and other enclosed electrical assemblies exposed to fluctuating ambient humidity.

Key Features

  • Humidity-Activated Switching: Activates the heater and/or fan when a preset relative humidity inside the enclosure is exceeded, raising RH above the dew point to prevent condensation on assemblies and electronic components.
  • Flexible Mounting: Mounts on a vertical or horizontal 35 mm support rail to EN 50 022, or snap-fastens into the enclosure section or onto the mounting plate using the supplied adapter.
  • Time-Saving Connection: Terminal strip with a screw connection accessible from outside the enclosure for fast, straightforward wiring without opening the device housing.
  • Rated Operating Voltage: 24 V - 250 V, 1~ AC and 24 - 48 V (DC) for broad compatibility with control circuit power sources.
  • Finish: RAL 7035 housing color for a consistent enclosure appearance.
  • Compact, Lightweight Design: 0.1 kg weight, packaged 1 pc(s) per unit for straightforward stocking and installation.

Rittal 3118000 – Frequently Asked Questions

1) Will the Rittal 3118000 hygrostat mount on standard 35 mm DIN rail in my control cabinet?
Yes. The 3118000 hygrostat mounts on a 35 mm support rail to EN 50 022, run either vertically or horizontally. If you have no spare rail, it also snap-fastens directly into the enclosure section or onto the mounting plate using the adapter that comes with it.
2) What control voltage can I wire a Rittal 3118000 hygrostat to?
Rated 24 V to 250 V, 1~ AC, and 24 to 48 V DC. That covers a 24 VDC control circuit, 120 V, and 230 V single phase, so you normally don't need a separate control transformer for it.
3) What is the difference between a hygrostat and a thermostat for an enclosure heater?
A thermostat switches on temperature; the 3118000 switches on relative humidity. It energizes the heater and/or fan once a preset RH inside the enclosure is exceeded, which raises the air temperature and pushes RH back below the dew point so moisture doesn't condense on boards and assemblies. If your problem is cold components or freezing, you want a thermostat. If your problem is condensation from swinging ambient humidity, this is the control you want. Many cabinets use both.
4) Does the Rittal 3118000 hygrostat include a heater, or do I have to order that separately?
It's the control only. The 3118000 is a humidity switch that turns a heater and/or fan on and off; the enclosure heater or filter fan is a separate order. Size the heater or fan to the cabinet and make sure its load is within the hygrostat's 24-250 V AC switching range.
5) Can I wire the hygrostat without opening up the device?
No need to. The 3118000 uses a terminal strip with screw connections reachable from outside the enclosure, so you land conductors without taking the housing apart. Useful when you are adding condensation control to a cabinet already populated and energized nearby.
6) How is the Rittal 3118000 hygrostat packaged and how much does it weigh?
One piece per packaging unit, 0.1 kg. It's a single compact device, so for a multi-cabinet standardization job you order one per enclosure.
7) What is the Rittal part number for the DIN rail hygrostat?
Rittal 3118000. That is the manufacturer part number for the DIN rail mount hygrostat rated 24-250 V, 1~ AC and 24-48 V DC.
8) Will this hygrostat match the look of the inside of my Rittal cabinet?
The housing is RAL 7035 light grey, the same shade Rittal uses on its enclosure interiors and mounting plates, so it blends in on a panel rather than standing out.
