Small drives and motors with a power output of up to 4kW are frequently used in control technology and machine design. In the process, sometimes both rotational directions (forward/reverse) need to be controlled and the drives have to be protected against possible errors. Also, it must be ensured that they can be reliably and safely shut off through an external Emergency Stop function in the event of a breakdown. MOTUS®ContactronControl from Wöhner combines these four important requirements into one device.
The MOTUS®ContactronControl is an extraordinarily durable innovation due to its hybrid switching technology, resulting in a smooth switching functionality. The built-in semiconductor switches without wear. The continuous current is carried by a mechanical contact. This keeps the load on the mechanical switching element extremely low, allowing the size of the relay to be considerably reduced. The combination of overload, short-circuit and safety functionality, integrated into a single device, also guarantees minimal connection effort.
The MOTUS®ContactronControl relies on CrossLink® Technology. The device is supplied with an adapter for the Systems 30Compact and 60Classic or for DIN rail mounting. With all versions, the contacts of the CrossLink® adapter remain covered to protect them from being touched when the Electronics module device is removed.
Flexibility is guaranteed through three current sizes. Within the range of 0.075A to 9A, the devices can be finely adjusted. In case of an overload or short circuit, the built-in electronics safely shut the unit down. In special fault cases, the integrated fuses provide additional protection. The fuses are simply exchanged and the device is ready to go again. Furthermore, with the UL approval, the requirements for the North American market are fulfilled.
