The speed monitor, manufactured by Bihl+Wiedemann, is part of the large range of AS-i safety products distributed by TURCK in the United States.
The speed monitor may be efficiently programmed using a configuration push-button or by using AS-i control tools. When the speed falls below the designated threshold, the device sends a signal to AS-i. The monitor also employs an integrated chip card to record all programmed parameters. With this feature, the device does not require reprogramming to regain access to the machine after a controlled stop.
