D521.12 Single Channel Speed Monitor Card

Single Channel Speed Monitor Card D521.12 can be used to monitor motors, pumps, feeders, gears, drums and small turbines. It can provide overspeed protection under any required speed value, including static state. At the same time, the single channel speed monitor can be used together with sensors, tachogenerators, incremental encoders or magnetic induction sensors.

For single channel processing, the security is completely determined by the device configuration. In this case, redundancy is not provided. If a fault is detected, the entire system will alarm and shut down immediately. For dual channel processing, you can select how to set it according to requirements. In principle, the two monitors operate independently, but the alarm display can be realized through linkage.
