136294-01 is the internal-termination I/O module for isolated +4 to +20 mA inputs in a Bently Nevada 3500/62 Process Variable Monitor assembly. It provides the rear field interface while the associated front monitor performs signal conditioning, display and alarm processing.
With 136294-01, field wiring terminates at the rear module and does not use the external termination blocks required by an external-termination configuration. The input path has a published 50 Ω impedance and 500 V isolation.
Specify 136294-01 only after verifying the front 3500/62 monitor, signal type, termination architecture and approval requirements. It is not the ±10 Vdc option and does not include the intrinsic-safety barriers used by the barrier I/O version.

Application Decisions
Signal & Termination Architecture
Confirm that every connected channel uses an isolated 4–20 mA signal.
Verify the 50 Ω input impedance and 500 V isolation against the loop design.
Keep internal-termination wiring separate from external-block and barrier-I/O configurations.
3500/62 Rack Integration
Pair the rear module with the correct 3500/62 front monitor and rack position.
Confirm channel mapping, engineering units and configured ranges before return to service.
Treat the module as part of the 3500/62 assembly; it is not a standalone signal conditioner.

Isolated +4 to +20 mA I/O Module with Internal Terminations
How can I distinguish 136294-01 from the external-termination 136483-01 module?
136294-01 uses internal terminations. 136483-01 uses external terminations and requires the appropriate termination block and cable architecture.
Which front monitor should be verified before ordering 136294-01?
Verify that the installed assembly is a 3500/62 Process Variable Monitor; the official front-monitor spare listed with this family is 163179-03.
Can 136294-01 be used for a −10 to +10 Vdc input?
No. This is the isolated 4–20 mA option. The internal-termination voltage-input spare listed by Baker Hughes is 136491-01.
Does 136294-01 provide an intrinsic-safety barrier for the field loop?
No. Signal isolation is not the same as an intrinsic-safety barrier; the family lists 137110-01 as the 4–20 mA barrier I/O module with internal terminations.
What information should accompany an RFQ for 136294-01?
Send photos of the front monitor and rear I/O labels, terminal wiring, input signal type, rack position, approval requirements and quantity.
