Monitor family	3500/42M Proximitor Seismic Monitor
Channel capacity	Four channels
Supported input classes	Proximity, velocity or acceleration transducers
Rack position	One full-height front slot; matching I/O module uses one rear slot
I/O matching	Verify the installed I/O module and transducer type against the existing rack configuration

Installation

Rack installation
Install the monitor in one full-height front rack slot with the matching I/O module in the corresponding rear slot.

I/O verification
Confirm transducer type, termination style and installed I/O module before wiring or module exchange.

Commissioning
Configure channel type, scale, alarms and recorder outputs in the 3500 system before placing protection functions in service.

Environment

-30 to +65 deg C operating range with internal or external termination I/O.

Barrier I/O temperature
0 to +65 deg C operating range with internal barrier I/O.

Storage and humidity
-40 to +85 deg C storage; 95% noncondensing humidity.

FAQ

Q1. How can the quoted complete model be verified?

The quotation, photos and supplied assembly should identify 3500/42M 140734-02. Also verify that it is the four-channel Proximitor Seismic Monitor and that its rack and I/O arrangement matches the application.

Q2. How can New, Used or Refurbished condition be distinguished?

Request photos of the front panel, connectors, PCB edges, rack guides and labels. Scratched insertion surfaces, contaminated connectors, replaced components or altered labels can indicate prior use or refurbishment.

Q3. How can supplier legitimacy be checked?

Confirm the supplier legal entity, address, traceable quotation, invoice beneficiary, return policy and ability to provide model-specific photos. Do not accept a generic 3500/42M image as proof of stock.

Q4. What should an engineer confirm before purchase?

Check four-channel requirements, input transducer classes, 7.7 W power, 241.3 x 24.4 x 241.8 mm board dimensions, one front rack slot, corresponding rear I/O type and required operating-temperature range.

Q5. What evidence should be requested before payment?

Request timestamped photos of the complete model label, front panel, rear connections or PCB interface, packaging and traceable serial or date markings, plus confirmation of the matching I/O module.

Q6. Can a similar suffix or current spare replace 140734-02?

Do not assume equivalence from a family name or suffix. Compare the installed rack, firmware or configuration requirements, transducer inputs and I/O module before approving any substitute.
