XM-220 DUAL SPEED MODULE
XM-220 DUAL SPEED MODULE
EVERYTHING ABOUT SPEED IN A
DISTRIBUTED ARCHITECTURE
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.
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 Rockwell Software’s RSMACC Enterprise Online software system
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.
SPECIFICATIONS
Communications
DeviceNet:
• Standard DeviceNet protocol for all functions
• Available Electronic Data Sheet (EDS) file provides
support by most DeviceNet compliant systems
• Autobaud to 125kb, 250kb or 500kb
The XM-220 uses only the DeviceNet protocol, not power.
Module power is provided independently.
Side Connector: All XM measurement and relay modules
include side connectors that allow interconnecting
adjacent modules thereby simplifying the external wiring
requirements. The Interconnect provides primary power,
DeviceNet communication and the circuits necessary to
support expansion modules such as the XM-441
Expansion Relay module.
Serial: Local configuration via Serial Utility Program
• RS-232 via mini-connector or terminal block
• Baud rate auto baud to 19200
Inputs
2 Tachometer Inputs:
±25V (50V maximum peak to peak)
• Eddy current transducer signals
• Magnetic pickups
• TTL output devices
Input Impedance:
120k ohms minimum
Speed/Frequency Range:
1 to 1,200,000 RPM
0.0167 to 20,000Hz
Speed Measurement Error:
1 to 240 RPM: ±0.2 RPM
241 to 12,000 RPM: ±2 RPM
12,001 to 20,400 RPM: ±5 RPM
20,401 to 120,000 RPM: ±20 RPM
120,001 to 360,000 RPM: ±50 RPM
360,001 to 1,200,000 RPM: ±160 RPM
Sensor Fault Detection:
• Eddy Current Transducer:
Bias voltage is compared with user defined fault limits
• Magnetic pickups:
A current source is available for biasing passive magnetic
pickups to detect open or short circuits
Outputs
4-20mA Outputs:
• Each output is independently programmed to represent
speed or acceleration, from either channel
• 2 isolated outputs
• 300 ohm max load
Buffered Outputs:
• 1 active buffer per input channel
• Output range configurable by wiring:
-24V to +9V
-4.7 to +24V
-4.7 to 9V
• Third buffered output available when the module is
configured for single redundant channel mode. Out-puts
a TTL level square-wave that corresponds to the active
input signal.
Indicators
6 LEDs:
• Module Status -red/green
• Network Status - red/green
• Channel 1 Status - off/yellow/red
• Channel 2 Status - off/yellow/red
• Startup - off/yellow
• Relay - off/red
Measurement Modes
Dual Channel:
Inputs are used independently to perform two separate
speed, acceleration and peak speed measurements
Single Redundant Channel:
One sensor is used to perform the speed, acceleration
and peak speed measurement. If the current sensor fails
the module automatically switches to the second
(redundant) sensor
Reverse Rotation:
Two sensors are used to monitor both the speed and
direction.
