Overview Manuals Sensor Inputs Outputs and Relays Network Setup Product Applications

Features:

  • Two independent tachometer inputs for speed-related monitoring
  • 1–1,200,000 rpm measuring range for varied rotating assets
  • Two isolated 4–20 mA outputs with relay and network alarming
The XM-220 converts tachometer pulse trains into speed and protection variables used by local relays, analog outputs, and the connected monitoring network.

Its value lies in channel configuration: sensor behavior, pulses per revolution, alarm logic, and output scaling determine whether the same hardware suits a particular machine.

Commissioning should prove both measurement accuracy and the complete alarm-to-shutdown path before normal operation resumes.

The 1440-SPD02-01RB Allen-Bradley is listed as Active / Available from OEM.

Description
Allen-Bradley 1440-SPD02-01RB is an XM-220 dual speed module for machinery monitoring and protection. Two independent tachometer inputs allow the module to measure rotational speed, acceleration, zero-speed, reverse rotation, and related timing conditions.

1440-SPD02-01RB supports a measuring range from 1 to 1,200,000 rpm. Two isolated 4–20 mA outputs can retransmit configured measurements, while its relay and network outputs can provide configured signals to a wider monitoring or trip scheme; final protective action depends on the complete machine circuit and validated logic.

Application approval for 1440-SPD02-01RB should match the sensor type and pulse pattern, expected speed range, relay logic, analog scaling, network configuration, terminal base, and power arrangement. Where a relay is used in a protective scheme, prove the complete downstream path under the site's controlled commissioning procedure before relying on it.

Technical notes
Before commissioning 1440-SPD02-01RB, confirm sensor pulse characteristics, input channel assignment, maximum expected speed, relay voting and failsafe states, analog-output scaling, network node settings, and terminal-base wiring. Test zero-speed, overspeed, loss-of-signal, and trip paths with the machine under controlled operating authority. Confirm enclosure grounding and environmental limits during final inspection.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can 1440-SPD02-01RB be ordered without checking the speed sensor?
No. Verify sensor type, power, pulse amplitude, target pattern, pulses per revolution, expected frequency, and wiring before selecting or configuring the module.
What should be checked when 1440-SPD02-01RB shows a stable but incorrect speed?
Compare pulses per revolution, channel assignment, sensor gap, target geometry, input frequency, and engineering-unit scaling before replacing the module.
What can cause an intermittent zero-speed indication on 1440-SPD02-01RB?
Investigate sensor gap, loose wiring, target runout, weak pulse amplitude, noise, grounding, and channel thresholds. Capture the raw signal condition before changing alarm delays.
Can relay settings for 1440-SPD02-01RB be copied without a functional test?
No. Confirm relay logic, energize-to-trip or de-energize-to-trip behavior, delays, latching, voting, and the final shutdown circuit under controlled conditions.
Which data should be backed up before replacing 1440-SPD02-01RB?
Save the node address, channel configuration, pulses per revolution, alarm setpoints, relay assignments, analog scaling, network mapping, and terminal wiring record.
What should be checked before enabling a trip from 1440-SPD02-01RB?
If the relay is used in a trip scheme, prove the sensor input, pulses per revolution, scaling, setpoints, delay, latching and failsafe state, relay direction, and downstream trip path under the site's controlled commissioning procedure.
