PRODUCT DESCRIPTION
Four channel relay module
Bently Nevada 3500/32 125712-01 is a four-channel relay module. The four-channel relay module uses configured alarm-drive logic to produce relay outputs from rack monitoring conditions. Each output can implement a separate voting function using supported alarm inputs. The front module and its corresponding rear I/O form the documented relay arrangement.
The historical manufacturer spare table identifies 125712-01 as the original 3500/32 four-channel relay module. It lists 125720-01 separately as the rear relay I/O. Confirm both assemblies and the installed logic before replacement; the spare number does not establish a delivered firmware version.

ACTUAL APPLICATIONS
Applications for original 3500/32 relay system
These applications describe manufacturer-documented family use. They do not establish that this exact ordering code was installed at a named customer site.
-
01 · ALARM OUTPUTS
Rack alarms to external circuits
The relay module takes configured alarm conditions from monitor channels and switches the selected outputs. The field load must remain within the applicable contact ratings. -
02 · VOTING LOGIC
Combining machinery alarm conditions
AND and OR expressions combine selected Alert or Danger signals from one or multiple monitor channels. Each output is programmed for its own intended response. -
03 · MAINTENANCE
Restoring the original relay arrangement
Replacing the correct front module requires the matching rear I/O and saved rack configuration. Preserve channel operating mode and test the intended alarm response under approved maintenance procedures.

FOUR CHANNEL RELAY MODULE
Integrating 3500/32 125712-01
The four-channel relay module uses configured alarm-drive logic to produce relay outputs from rack monitoring conditions. Each output can implement a separate voting function using supported alarm inputs. The front module and its corresponding rear I/O form the documented relay arrangement.
The original 3500/32 uses 3500 Rack Configuration Software for alarm-drive logic and is installed to the right of the rack interface module. Triple-modular-redundant applications require the separately documented 3500/34 TMR relay module, not this standard four-channel unit.
Follow manual 129771-01, match the rear relay I/O and verify every configured alarm expression. Check the normally energized or de-energized selection and actual load against all contact limits. Treat the cited contact ratings as resistive-load specifications, not universal motor-load ratings.
Features:
- Match exact assembly, interface generation, connection and installation instructions
- Follow the applicable installation instructions
- Confirm unverified configuration details
The 3500/32 125712-01 four-channel relay module requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Replacement of 3500/32 125712-01 requires comparing exact assembly, interface generation, connection and installation instructions. A shared base family or similar appearance does not establish a drop-in replacement for the complete ordered assembly.
The original 3500/32 uses 3500 Rack Configuration Software for alarm-drive logic and is installed to the right of the rack interface module. Triple-modular-redundant applications require the separately documented 3500/34 TMR relay module, not this standard four-channel unit.
No verified exact-order discontinuation date, product revision or designated successor is asserted. Document revisions identify the reference literature, not hardware changes to the supplied product. Unconfirmed replacement options must be resolved before substitution.
Features:
- Preserve the complete ordering identity
- Compare the installed electrical and mechanical interfaces
- Do not infer hardware revisions or successor models
The 3500/32 125712-01 four-channel relay module requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 3500/32 125712-01
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
How is 3500/32 125712-01 identified?
The historical manufacturer spare table identifies 125712-01 as the original 3500/32 four-channel relay module. It lists 125720-01 separately as the rear relay I/O. Confirm both assemblies and the installed logic before replacement; the spare number does not establish a delivered firmware version. -
What does this component do?
The four-channel relay module uses configured alarm-drive logic to produce relay outputs from rack monitoring conditions. Each output can implement a separate voting function using supported alarm inputs. The front module and its corresponding rear I/O form the documented relay arrangement. -
Which equipment and interfaces must match?
The original 3500/32 uses 3500 Rack Configuration Software for alarm-drive logic and is installed to the right of the rack interface module. Triple-modular-redundant applications require the separately documented 3500/34 TMR relay module, not this standard four-channel unit. -
Where is this product used?
The relay module takes configured alarm conditions from monitor channels and switches the selected outputs. The field load must remain within the applicable contact ratings. -
What matters when installing this component?
Follow manual 129771-01, match the rear relay I/O and verify every configured alarm expression. Check the normally energized or de-energized selection and actual load against all contact limits. Treat the cited contact ratings as resistive-load specifications, not universal motor-load ratings. -
Is this module suitable for a TMR relay application?
The historical manufacturer note requires 3500/34 for TMR applications. Do not treat ordinary configurable voting in 3500/32 as the same hardware architecture. -
Can 5 A be switched at every listed voltage and load?
No. The resistive-load limits apply together: 5 A maximum, 30 Vdc or 250 Vac maximum, and 120 W DC or 600 VA AC maximum. The source does not grant the same ratings for arbitrary inductive loads.
