Bently Nevada 136294-01 Process Variable Monitor
The internal-termination isolated-current I/O execution used behind a compatible 3500/62 monitor.
Key Information
136294-01 is the Bently Nevada isolated +4 to +20 mA I/O module with internal terminations listed for the 3500/62 Process Variable Monitor. It is the rear field-interface module, not the six-channel front monitor itself.
The distinction matters because the 3500/62 family also includes voltage, isolated-current external-termination and intrinsic-safety barrier I/O executions. The installed termination method and input architecture must match the rack documentation.
Selection should retain the paired front monitor, rack slot, loop-power arrangement and transmitter records. This prevents an internal-termination spare from being substituted into an external termination or barrier installation.
Functions
Isolated current acquisition
Routes compatible +4 to +20 mA process signals to the paired 3500/62 monitor.
Rear-rack termination
Provides direct internal field termination at the monitor slot.
Channel separation
Maintains the isolated-current architecture identified for this I/O execution.
Protection integration
Supports alarm processing performed by the configured front monitor.

About IndustryParts
https://www.industryparts.com/Current-loop architecture is checked before supply
IndustryParts links the exact rear I/O part, front monitor identity, loop-power plan and termination method before preparing a 3500/62 proposal.
Installation
Record every loop
Capture transmitter type, loop power, polarity, cable screen, configured range and rack channel before conductors move.
Match the I/O architecture
Confirm internal termination and isolated-current requirements rather than selecting by 3500/62 family name alone.
Commission with known signals
Verify channel scaling, isolation behavior, alarms and system indications through the approved test plan.
Lifecycle
Pairing record
Keep the front monitor and 136294-01 identities together in the rack asset record.
Terminal condition
Inspect connector headers and conductor retention during planned outages.
Loop documentation
Preserve transmitter ranges, engineering units and alarm setpoints after any I/O exchange.

FAQ
Why must 136294-01 not be ordered as a generic 3500/62 module?
It is specifically the isolated-current rear I/O with internal terminations; the front monitor and other I/O styles use different part numbers.
What loop information should accompany a 136294-01 enquiry?
Provide transmitter ranges, loop-power source, polarity, isolation requirements, channel map and clear rear-rack photographs.
Can 136294-01 replace the external-termination I/O?
No. External termination uses a different I/O module and the matching termination block and cable architecture.
When is the barrier I/O used instead of 136294-01?
Use the documented barrier execution only where the approved intrinsically safe loop design requires it.
What proves 136294-01 is ready after service?
Known-current injection, correct engineering scaling, stable channel status and completed alert and danger tests provide the acceptance record.
