Replacement
3500/42M has two rear-card variants: 128229-01 internal integrated terminal type (this set, sensor wires connect directly onto rear-card terminals) and 128240-01 external terminal type requiring a separate external terminal block - the two rear cards are NOT interchangeable. Front card 176449-02 works with both rear cards. Distinguished from the old-generation 3500/42 (non-M): the 3500/42M is the updated SIL2-compliant revision for modern TSI projects, standard tender-required model.
Frequently Asked Questions
What is 3500/42M used for?
3500/42M is a Bently Nevada 4-channel proximitor seismic monitor module for the 3500 rack, composed of the 176449-02 front card and 128229-01 rear card, for vibration, thrust and position monitoring of rotating machinery.
What is the difference between rear card 128229-01 and 128240-01?
128229-01 is the internal-terminal type (this set): field sensors connect directly on the rear-card terminals. 128240-01 is the external-terminal type requiring an extra terminal block. They cannot cross-replace.
Can 3500/42M work independently?
No. It must be installed inside a complete Bently Nevada 3500 rack with power supply and related rack modules to realize full monitoring and protection function.
Does 3500/42M meet tender requirements?
Yes. It fully matches the tender standard "Proximitor / Seismic Monitor, Model 3500/42M or equivalent, Bently Nevada or equivalent".
