More Information

Overview Manuals Sensor Wiring Output & Power Ex i System Product Applications

Features:

  • Dual Ex i inputs: accepts two intrinsically safe temperature or resistance circuits.
  • Safe-area outputs: provides two configurable 0/4-20 mA signals.
  • Channel diagnostics: includes separate LF1 and LF2 line-fault indication.
RTDs, thermocouples and potentiometers can be configured within the documented device limits.

The transmitter isolates hazardous-area sensor circuits from the safe-area control system.

Terminal power or pac-Bus can be used according to the installed cabinet design.

Apter Power can provide quotations, documentation and Ex i loop review for the R. STAHL 9182/20-51-11 Two-Channel Active Ex i Temperature Transmitter.

Important Notice: Verify the complete catalog number, document revision and installed Ex i system before use.
  • Channel configuration: each input channel can be set for the supported RTD, thermocouple or potentiometer function.
  • RTD connection: the selected 2-, 3- or 4-wire Pt100 arrangement must match the actual sensor wiring.
  • Thermocouple reference: thermocouple measurement requires the documented reference-junction arrangement for the selected sensor type.
  • Per-channel setup: sensor type and measuring range are configured separately for each channel.
  • Analog outputs: provides two configurable 0/4-20 mA outputs, so each receiving channel must use the corresponding range.
  • Supply boundary: the 18 to 31.2 V DC supply range includes nominal 24 V operation and must match the cabinet power design.
  • Fault reporting: LF1 and LF2 provide channel-specific line-fault indication for commissioning and diagnostics.
  • Power integration: terminal supply or pac-Bus integration must follow the selected cabinet arrangement.
  • Hazardous-area inputs: sensor circuits use intrinsically safe Ex i protection.
  • Galvanic separation: isolates inputs, outputs and auxiliary power.
  • Entity evaluation: each connected sensor circuit uses its own parameters.
  • Operating mode: ISpac Wizard or documented DIP switches set configuration.
  • Hazardous-area temperature: feeds two sensor signals to safe-area DCS inputs.
  • RTD loops: adds intrinsic-safety separation to resistance measurements.
  • Thermocouple conversion: isolates and converts signals to 0/4-20 mA.
  • Dual-channel cabinets: supports pac-Bus power and line-fault indication.
Description
9182/20-51-11 is a two-channel active R. STAHL ISpac Ex i temperature transmitter. It accepts intrinsically safe temperature-sensor or resistance-transmitter signals from the hazardous area and transfers two configurable current outputs to the safe area.

The input side of 9182/20-51-11 supports common resistance thermometers, thermocouples and potentiometers, with configuration through ISpac Wizard or the documented DIP-switch functions for this type family.

For a compatible installation, 9182/20-51-11 should be matched to both sensor circuits, the 0/4-20 mA receiving channels, auxiliary supply, pac-Bus or terminal arrangement and the hazardous-area entity parameters.

Technical notes
Each 9182/20-51-11 Ex i sensor circuit should be evaluated with its cable values and entity parameters. During commissioning, LF1 and LF2 provide separate line-fault indication, while the configured 0/4-20 mA fault response determines how each safe-area control channel reports a wiring fault.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How should the RTD wiring mode be selected on 9182/20-51-11?
Select the 2-, 3- or 4-wire mode that matches the actual sensor circuit. The wrong mode changes how lead resistance is compensated and can create a temperature error even when the sensor type is correct.
Can the two channels of 9182/20-51-11 use different temperature sensors?
Yes, each channel can be configured for its own supported sensor type and measuring range. The hazardous-area parameters and safe-area output scaling still need to be evaluated separately for each channel.
What does one illuminated LF indicator mean on 9182/20-51-11?
LF1 or LF2 identifies a line fault on the corresponding channel, so the associated sensor circuit and cable are the first diagnostic scope. The configured output fault response should also be checked at the control-system input.
Which power arrangement should be retained when installing 9182/20-51-11?
Use the documented terminal-supply or supported pac-Bus arrangement that matches the cabinet design. Power distribution, fault signaling and carrier connections should be treated as one installation choice rather than mixed informally.
What must be established before 9182/20-51-11 is connected to a hazardous-area sensor?
The sensor and cable entity parameters, area classification, wiring method and control drawing must all fit the Ex i circuit. A compatible signal type alone is not sufficient for intrinsic-safety compliance.
What should be proven during commissioning of 9182/20-51-11?
Apply representative sensor values to each channel and confirm the configured 0/4 to 20 mA scaling, channel assignment and line-fault response. This verifies both normal measurement and the control system’s reaction to a field-circuit fault.
