CMSS56 - Networked DC Motor Speed Sensor
|
The CMSS56 module measures the speed of a DC electric motor based on the ripple in the motor's supply current. No physical contact or line of sight is required. Allows for test of correct installation and/or operation of motor embedded inside the end product. Click for advantages of using current to sense motor speed. The input to the module can be a typical current shunt, Hall effect sensor, or other current measurement device. The analog inputs to the module are rugged and electrically isolated from the main power supply. The module has a secondary analog input channel that can be used to measure some other physical property (such as pressure, vibration, voltage) simultaneously. Seven digital inputs and seven digital outputs programmable from network interface. The module is available with DeviceNet, Ethernet, or Profibus interface. Contact factory for specialty/custom variations of this module to exactly meet your application's requirements. |
