Products Description

125680-01

Model 125680-01 from Bently Nevada functions as a four-channel Proximitor input/output card, engineered to work alongside the 3500/40M Proximitor Monitor unit. Mounted on the back side of the 3500 series rack, this component features built-in field wiring terminals, enabling connection of as many as four separate Bently Nevada proximity probe signal lines to its matching monitor module.

This hardware unit delivers measurement capacity critical to rotating equipment protection, covering parameters including radial vibration, axial thrust displacement, rotor eccentricity, differential thermal expansion and REBAM signals; measurable metrics vary based on the channel setup programmed within the 3500/40M monitor. Classified as a regular non-isolation I/O card, the 125680-01 omits integrated intrinsically safe barrier circuitry. It cannot operate independently as a monitoring device, and requires matching 3500/40M monitor hardware for full functional deployment.

Key Features

  • Designed for the Bently Nevada 3500/40M Proximitor Monitor

FAQ

 

 

1. What is the Bently Nevada 125680-01?

The 125680-01 is a Proximitor I/O module with internal terminations. It connects proximity transducer field wiring to a 3500/40M Proximitor Monitor.

2. Is the 125680-01 the main 3500/40M monitor?

No. It is the rear I/O module. The corresponding 3500/40M monitoring module is installed in the front slot and performs signal processing, alarm comparison, and machinery-protection functions.

3. How many transducer signals does the module support?

When paired with the 3500/40M, the module supports between one and four proximity transducer signals.

4. Does the 125680-01 include internal safety barriers?

No. The 125680-01 is a standard non-barrier I/O module. For internal barriers and internal terminations, the official 3500/40M spare part is 135489-04.

5. Does it require an external termination block?

No. Field wiring connects directly to the module through its internal terminations. External termination blocks and I/O cables are used with the 126615-01 external-termination version instead.
