Features:

  • Two position-monitoring channels for compatible proximity probes
  • Local alarm, buffered-output, and networked measurement paths
  • Configurable protection for documented displacement applications
The module turns conditioned proximity-probe signals into position variables used for indication and machinery protection.

Measurement quality depends on the entire probe chain and its mechanical reference, not only on the electronics module.

A controlled replacement preserves gap, scale, polarity, alarm direction, network mapping, and the final trip response as one configuration.

The 1440-TPS02-01RB Allen-Bradley may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Identify probe, extension cable, driver, sensitivity, and linear range.
  • Retain original channel polarity and mechanical reference.
  • Do not infer compatibility from connector fit alone.
  • Validate alert and danger directions against the mechanical measurement.
  • Check relay latching, delay, failsafe behavior, and destination wiring.
  • Test the complete shutdown chain under controlled authorization.
  • Record node settings and channel mapping before removal.
  • Separate local probe faults from network communication faults.
  • Restore only a configuration verified for the installed machine.
  • Axial-position monitoring
  • Differential-expansion measurement where documented
  • Legacy XM machinery-protection maintenance
Description
Allen-Bradley 1440-TPS02-01RB is a two-channel position monitoring module in the XM machinery-protection family. It conditions proximity-probe signals for position-related measurements and makes configured values available to local alarms, buffered outputs, and the monitoring network.

The two input channels of 1440-TPS02-01RB can be applied to documented functions such as thrust or axial position, valve position, differential expansion, and case expansion when the probe, driver, target, range, and polarity are correctly matched. The module does not by itself establish that an existing probe system is suitable.

A replacement or new installation of 1440-TPS02-01RB should preserve probe and driver part numbers, scale factor, mechanical zero, gap voltage, channel polarity, alarm setpoints, relay logic, network node settings, and terminal wiring. Recommission each channel against known mechanical reference data before relying on its relay or alarm output in a protective scheme.

Technical notes
Before installing 1440-TPS02-01RB, match the probe, extension cable, driver, sensitivity, range, polarity, terminal base, and network configuration. Record gap voltage and mechanical reference before removal. After replacement, validate channel scaling, alarm direction, relay action, buffered outputs, and the complete machine trip path. Record as-left readings for future maintenance comparison.

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-TPS02-01RB be replaced without identifying the probe system?
No. Record the probe, extension cable, driver, sensitivity, range, polarity, target, and terminal-base wiring before selecting or configuring the replacement.
Why can position shift after an otherwise successful 1440-TPS02-01RB change?
A changed scale factor, polarity, mechanical zero, probe gap, channel assignment, or driver type can move the displayed value. Reconcile these items before changing alarm setpoints.
What should be done if a channel of 1440-TPS02-01RB reads full scale after installation?
Keep protection changes controlled and check probe continuity, driver power, connector seating, wiring polarity, gap voltage, channel configuration, and the selected measurement range.
Can alarm values for 1440-TPS02-01RB be copied without checking relay direction?
No. Validate increasing or decreasing alarm direction, latching, delays, failsafe state, relay assignment, and the final shutdown response.
Does Rockwell list a planned replacement for 1440-TPS02-01RB?
Rockwell lists 1440-TPS02-01RB as discontinued with no planned Rockwell Automation replacement. Any alternative requires an engineering review of the sensors, wiring, monitoring architecture, relay use, and protection logic.
What commissioning evidence should be retained for 1440-TPS02-01RB?
Retain probe and driver identities, scale factor, mechanical reference, gap voltage, polarity, channel configuration, alarm and relay tests, network settings, terminal wiring, and the site's return-to-service record.
