Motor brake relay
GB 9034

The electronic braking devices enable wear-free braking of three-phase and alternating current asynchronous motors. The braking devices are used for drives that must be reliably braked for safety and functional reasons. Depending on the device version and the user‘s specification, the braking current switches off after a set braking time or via the integrated standstill detection after the motor has come to a standstill. With standstill-dependent braking, a potential-free signal contact signals if the motor has not come to a standstill within the maximum braking time.
