220 Dual Speed Module The XM® series from Rockwell Automation is the world's first machine monitoring and protection system designed as a distributed network of modules deployed on an open standard industrial bus. The XM-220 Speed Module is an intelligent 2-channel measurement module that accepts input from two tachometers of any standard type including eddy current probes, magnetic pickups, optical tachometers and TTL output devices. The module measures speed, rotor acceleration and peak speed and is capable of detecting zero speed, locked rotor and reverse rotation. The module may also serve as a component of an Electronic Overspeed Detection System (EODS). The XM-220 can be configured to operate in three different modes. This controls how the sensors are used to calculate the speed, acceleration, and peak measurements. Dual Channel Mode This is the default mode. The two sensors are used independently to perform two separate speed, acceleration, and peak speed measurements. Single Redundant Channel Mode One sensor is used to perform the speed, acceleration, and peak speed measurement. The module automatically switches to the second (redundant) sensor when a transducer or tachometer fault is detected on the current sensor. Reverse Rotation Mode The two sensors are used to monitor both speed and direction. The first sensor measures the speed, acceleration, and peak speed in the forward direction. The second sensor measures the speed, acceleration, and peak speed in the reverse The module includes a single on board relay, expandable to five, two 4-20mA outputs, and a buffered output for each input. A third buffered output is available when the module is functioning in the single redundant channel mode. This buffered output signal corresponds to the active input signal. It is provided so that connected devices, including other XM modules, can be assured of always receiving a valid speed signal - as long as at least one of the two redundant speed inputs is functioning properly. The XM-220 can operate stand alone, or it can be deployed on a standard or dedicated DeviceNet network where it can provide real-time data and status information to other XM modules, PLCs, distributed control systems (DCS), and Condition Monitoring Systems. Configuration can be performed either locally or remotely via the DeviceNet network. Local configuration is provided by a simple, intuitive Serial Configuration Utility executing on a PC connected to the modules serial communications port. Remote configuration can be performed from any networked PC executing either any standard DeviceNet configuration software, or the XM specific configuration tool included in RSI's RSMACC EOL software system.
