Allen-Bradley 1440-DYN02-01RJ Dynamic Measurement Module

Configured for vibration and rotational speed signal acquisition in XM condition monitoring systems, the Allen-Bradley 1440-DYN02-01RJ (1440-DYN02-01RJ dynamic measurement module) provides direct electrical processing for dynamic transducer and tachometer input channels.

Suffix Breakdown & Model Matrix

The supplied documentation identifies 1440-DYN02-01RJ as a fixed XM Series catalog model. No official suffix segmentation or configurable ordering matrix was specified in the provided material.

Hardware Specifications

Deterministic ControlNet Signal Processing

The module transfers dynamic waveform and tachometer data through the XM ControlNet monitoring structure using the 1440-ACNR communication adapter. Signal acquisition timing is synchronized through scheduled network communication intervals for vibration and rotational speed monitoring functions.

The two dynamic input channels operate with input impedance greater than 100 kOhm to reduce loading effects on connected transducers. Tachometer input circuitry supports rotational signal acquisition from low-speed shafts through high-frequency pulse sources up to 20 kHz.

The module processes dynamic measurement data through the XM architecture using dedicated transducer excitation at 24 VDC with a maximum current supply of 60 mA. ControlNet output operation depends on valid adapter communication and terminal base connectivity.

Frequently Asked Questions

Q: Does the 1440-DYN02-01RJ require a separate communication adapter?
A: Yes. The module operates with the 1440-ACNR ControlNet adapter for ControlNet network communication.

Q: What type of mounting base is required for installation?
A: The module is designed for installation on a 1440-TBS-J terminal base assembly.

Q: Can the tachometer input process high-frequency rotational signals?
A: Yes. The tachometer input supports frequencies up to 20 kHz and rotational speed ranges up to 1.2 million rpm as specified in the supplied data.

Field Installation Guidelines

Install the module inside a grounded industrial enclosure with adequate spacing between vibration signal wiring and high-current motor conductors. Dynamic transducer cables should use shielded twisted-pair construction with shield grounding terminated at a single enclosure reference point.

Verify ControlNet segment integrity and adapter communication status before commissioning the module. Improper network termination or node configuration can interrupt dynamic waveform transmission.

Avoid routing tachometer input wiring adjacent to variable frequency drive output cables or relay switching conductors. Excessive electromagnetic interference may introduce unstable pulse detection or incorrect rotational speed calculations.

Inspect the 1440-TBS-J terminal base for complete mechanical engagement before energizing the transducer supply circuit. Loose terminal seating may generate intermittent vibration channel loss during operation.
