PRODUCT DESCRIPTION
Two voltage channels with configurable speed and filtering
Siemens 6ES7134-4LB02-0AB0 is a two-channel High Feature voltage input module for SIMATIC ET 200S. It accepts ±5 V, ±10 V and 1–5 V signals, using sigma-delta conversion and four input bytes. The module does not supply power to voltage transmitters.
Without interference-frequency suppression, the module cycle is 0.5 ms; enabling suppression changes the timing. Isochronous operation is supported only with smoothing and suppression disabled. Configurable diagnostics include wire-break checking specifically for the 1–5 V range, with red SF indication for reported faults.

ET 200S HIGH FEATURE VOLTAGE INPUTS
Choose acquisition timing together with filtering and range
Match each channel to ±5 V, ±10 V or 1–5 V and provide any required transmitter power separately, because this voltage module has no transmitter supply. Confirm the selected terminal module and differential signal polarity. The inputs occupy four bytes, while the chosen S5 or S7 representation determines how the controller must interpret the returned values.
Set timing and filtering as a coordinated choice. With interference-frequency suppression disabled, the module cycle is 0.5 ms; 60 Hz or 50 Hz suppression raises it to 18 or 21 ms. Smoothing uses one, four, 16 or 32 cycles, but neither smoothing nor suppression may be configured for the documented isochronous mode.
Integrate range diagnostics and hardware interrupts with the controller's actual fault-handling strategy. Wire-break checking is confined to the 1–5 V range, and limit interrupts depend on the process-interrupt mechanism not being overloaded. Observe the channel potential limits and shielding instructions; increased permitted common-mode voltage does not mean that the two inputs are individually isolated.
Features:
- Range-specific signal interpretation
- Explicit speed/filter trade-off
- Conditional diagnostics and interrupts
The Siemens 6ES7134-4LB02-0AB0 requires the documented hardware configuration, installation conditions and interface arrangement to be verified before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Verify the complete 4LB02 order number and the existing voltage signal ranges before choosing a replacement. Do not substitute a current-input module or infer a wider measuring range from the permissible common-mode voltage. Retain the terminal-module selection, input address interpretation and separate transmitter supply arrangement as part of the recorded station configuration.
When replacing 6ES7134-4FB51-0AB0, use the explicit June 2013 Siemens recommendation as the starting point, not a promise of unchanged configuration. Compare cycle time, suppression, smoothing and diagnostic settings, then verify the interface and engineering configuration. The source specifically warns that a new configuration may become necessary for this recommended High Speed to High Feature replacement.
Qualified personnel should follow the station's applicable replacement procedure and inspect signal polarity, shielding and permitted potentials before commissioning. After parameterization, confirm L+ and wait for valid converted data. Check SF and diagnostic status, then test known voltages in the configured range. Ensure startup, overflow or deactivated-channel 7FFFH values are not accepted as normal process data.
Features:
- Exact voltage-module matching
- Documented 4FB51 replacement review
- Known-voltage and fault-code validation
The Siemens 6ES7134-4LB02-0AB0 requires replacement verification based on its complete order number, installed hardware, signal configuration and project documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 6ES7134-4LB02-0AB0
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Is the 0.5 ms cycle available with noise suppression enabled?
No. The manual gives a 0.5 ms module cycle without interference-frequency suppression, 18 ms with 60 Hz suppression and 21 ms with 50 Hz suppression. These module-cycle values are different from per-channel conversion time and should be used when checking station response. -
Can smoothing be used during isochronous operation?
No. The exact manual permits isochronous operation only when neither smoothing nor interference-frequency suppression is configured. Check both module parameters and the station timing before relying on synchronized acquisition. -
Does wire-break detection work on ±10 V signals?
The documented wire-break diagnostic applies only to the 1–5 V range. Do not assume equivalent open-circuit detection on ±5 V or ±10 V. Confirm the actual range and enabled diagnostic parameters before defining fault-handling logic. -
Are the two channels galvanically isolated from each other?
No. Siemens specifies isolation from the backplane and load supply, but not between channels. The increased permissible potential difference of 140 V DC or 100 V AC between inputs is not an isolation claim and does not change the voltage measurement ranges. -
Can 4LB02 replace the older 4FB51 High Speed module?
Siemens' June 2013 product information recommends 4LB02 as a replacement for 6ES7134-4FB51-0AB0, while warning that a new configuration may be necessary. Review voltage range, timing, diagnostics and station configuration; it is not an unconditional plug-and-play statement. -
Why can an input return 7FFFH after installation?
The code can occur before the first conversion, with missing L+, before or after incorrect parameter assignment, for overflow, or on a deactivated input. Read the diagnostic and operating state before interpreting it as a process voltage.
