Features:
- Four channels supply and measure 4–20 mA two-wire transmitters.
- HART V6 messages share each analog loop with the process-current signal.
- Wire-break and overcurrent thresholds separate open-loop faults from short-circuit conditions.
Siemens 6ES7134-7TD00-0AB0 converts four transmitter loop currents into ET 200iSP process values.
Each 6ES7134-7TD00-0AB0 channel adds HART communication without requiring a separate digital field cable.
Filtering and smoothing settings on 6ES7134-7TD00-0AB0 determine the update response of the reported measurements.
The Siemens 6ES7134-7TD00-0AB0 SIMATIC ET 200iSP 4-Channel Analog Input HART Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Two-Wire Current Measurement
- Loop supply: Each channel powers its connected two-wire transmitter from the module supply path.
- Process current: The transmitter controls a 4–20 mA loop that represents the measured process value.
- Conversion: Sigma-delta conversion turns the loop current into a digital value for the station.
- Load limit: The transmitter, cable, and termination resistance must remain within the documented loop-load boundary.
Analog and Digital Data on One Loop
- HART carrier: Digital HART communication is superimposed on the analog current signal.
- Channel identity: Commands and returned variables remain associated with the selected physical channel.
- Device data: The controller or engineering tool accesses supported transmitter information through the module.
- Commissioning: Polling address, channel assignment, current range, and device variables must match the installed transmitter.
Loop Fault Separation
- Wire break: A loop current below the documented threshold identifies an open or under-range circuit.
- Overcurrent: A value above the upper threshold identifies an overload or short-circuit condition.
- Transmitter supply: The channel supply is electronically protected against a field short circuit.
- Status review: Module diagnostics, channel value, HART status, terminal wiring, and loop power should be checked together.
Station and Channel Boundaries
- Backplane isolation: The analog circuitry remains isolated from the ET 200iSP backplane.
- Channel relationship: All four channels follow the potential grouping defined for this electronic module.
- Shielded cable: The documented cable length assumes the specified shielded loop installation.
- Enclosure: The IP30 module remains inside the ET 200iSP assembly and suitable protected installation.
