It operates effectively within a temperature range of -40°C to +80°C, boasts an IP 66 / IP 69 K protection class, and is rated for 24V and 5A. Its dimensions are 150 x 200 x 200 mm.

Key Features & Benefits

This modulator basically controls the air brakes on an axle – specifically, it manages the air pressure going to the brake chambers on either side of that axle. It’s a two – channel unit, meaning it handles one brake on each side, independently. It receives signals from the ABS system, and uses those to quickly apply or release the brakes on that axle, helping prevent wheel lockup. It also balances the braking force left to right, so you get a smoother, more controlled stop. It's all about fine control of the air pressure. Think of it as a smart valve. It sits between the air reservoir and the brake chambers. It doesn't do the braking itself – the chambers do that – but it's the brain telling them how much to brake. It’s a key component of the entire anti – lock braking system. It takes information from the wheel speed sensors, then uses that to adjust the air pressure to each wheel. It’s a pretty crucial piece of the puzzle for modern air brakes.

Symptoms, Risks & Replacements

Well, without this working right, your ABS system can’t do its job. You’ll notice if this fails – usually it's a loss of ABS function, the ABS light comes on, and the vehicle won’t stop as effectively, especially in slippery conditions. It also prevents wheel lockup, which can lead to skidding and loss of control. It's a safety item, plain and simple. It protects you from losing control during hard braking, and helps keep you and others on the road safe.
