The retrofittable module is clamped into the power supply of the brake. It detects the movement of the armature disk through an extended analysis of current and voltage and knows what state the brake is in.

In an extended version, the module is equipped with an additional board with a customer-specific interface (e.g. optical, WiFi, IO Link, OPC UA, etc.). Via this interface, it can supply data on switching time, current, voltage, resistance, power and relative starting current. This means that processes can also be evaluated, abnormalities in the machining process can be identified quickly and conclusions can be drawn from complex relationships.
