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.
