Features:
- Two current channels accept 0–20 mA or 4–20 mA signals from two-wire transmitters.
- A 0.1 ms minimum conversion time supports fast ET 200S measurement cycles.
- Configurable smoothing and loop diagnostics separate signal noise from wiring faults.
Siemens 6ES7134-4GB52-0AB0 converts two transmitter currents into four bytes of controller input data.
The protected transmitter-supply paths of 6ES7134-4GB52-0AB0 belong to the selected terminal-module wiring.
Isochronous use of 6ES7134-4GB52-0AB0 depends on a supported ET 200S station cycle.
The Siemens 6ES7134-4GB52-0AB0 SIMATIC ET 200S 2AI High-Speed 2-Wire Analog Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Transmitter-to-Controller Signal Path
- Field loop: Each two-wire transmitter modulates current in its assigned input circuit.
- Input conversion: The module measures loop current and converts it into a signed controller value.
- Range selection: The configured 0–20 mA or 4–20 mA range determines scaling and diagnostic behavior.
- Address mapping: Both converted values occupy the documented four-byte input area.
Response and Smoothing Relationship
- Conversion: The high-speed electronics provide the documented minimum conversion interval.
- Channel cycle: Both active channels are updated within the stated all-channel cycle.
- Smoothing: A larger smoothing factor averages more conversions and slows the visible response.
- Isochronous mode: Station timing must support the configured synchronous acquisition path.
Loop and Module Fault Separation
- Wire break: The 4–20 mA range can identify loop current below the documented diagnostic threshold.
- Overflow: A value outside the selected measuring range sets the associated overrange information.
- Parameter error: An unsupported range or station assignment produces a configuration-related diagnosis.
- Group fault: The SF indication requires channel diagnostics and supply conditions to be read together.
Terminal Module and Cable Boundaries
- Terminal module: The installed ET 200S terminal base routes loop supply and measured current to the electronics.
- Shielding: Long analog runs require the documented shield and reference arrangement.
- Loop supply: Transmitter voltage must remain adequate after cable and input voltage drops.
- Commissioning: Measure loop current before changing PLC scaling or substituting the module.
