XM-121 Absolute Shaft Technical Specifications
Product Feature Specification
Communications
DeviceNet
Side Connector
Serial
Standard DeviceNet protocol for all
functions
NOTE: The XM-121 uses only the DeviceNet
protocol, not power. Module power is provided
independently.
Available Electronic Data Sheet (EDS) file
provides support for most DeviceNet
compliant systems
Baud rate automatically set by bus master
to 125 kb, 250 kb, 500 kb
Configurable I/O Poll Response size and
Assembly helps optimize space utilization
within scanner input tables.
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.
RS-232 via mini-connector or terminal base
unit
Baud rate fixed at 19200.
NOTE: Local configuration via Serial
Configuration Utility.
