Supplied with full traceability and documentation. Request a... Price & Availability It is intended for use within Pepperl+Fuchs LB remote I/O (FieldConnex), where dependable operation and a precise fit are essential to keeping the plant running. Listed as Discontinued, it is offered as a maintained and verified spare that supports the continued operation of the installed base. Key technical specifications include: The Number of channels is 4. Its Rated voltage is rated at 12 V DC (only with LB9*** power supplies). For reference, the Output current is 0. 20 mA (short-circuit protected). The Max. load is 750 Ohm at 20 mA. Its HART communication is rated at Yes (primary and secondary variable). For reference, the Degree of protection is IP20 (when mounted on backplane). The Dimensions is 32.5 x 100 x 102 mm. Its Mass is rated at approx. 150 g. For reference, the Ambient temperature is -20. 60 C (some listings -40. 60 C). Notable features of this unit: Ex ia intrinsically safe outputs for hazardous-area field devices. HART communication via field bus or service bus. Line fault detection (LFD) with one LED per channel. Hot-swappable module, permanently self-monitoring with watchdog. Typical applications include Remote I/O installations in oil & gas, chemical and utility sites. It is compatible with or cross-references LB9*** backplane power supplies (required for 12 V DC operation), HART-capable control systems and field devices (valves, I/P converters, displays). Within industrial automation and process-control environments, components of this type are relied upon to keep critical equipment operating safely and efficiently. They are typically specified where uptime, repeatability and a predictable maintenance cycle matter more than upfront cost. Pepperl+Fuchs parts are widely used across power generation, manufacturing, oil and gas, water and process industries, where engineering teams standardise on proven series to simplify spares planning. When selecting a replacement, confirm the exact model designation and verify that the mechanical and electrical interface matches the unit currently installed. Cross-checking the order code, mounting style and connection type against the existing device helps avoid compatibility issues and unplanned downtime during a maintenance window. Where several variants exist, the suffix often defines voltage, range or firmware, so it should be matched precisely rather than approximated. This item is offered from our active stock of current and discontinued industrial parts. Each listing is verified against the manufacturer designation before shipment so you receive the correct part for your application. Availability and lead time vary by item; our team can confirm the fastest option for your required quantity and provide a formal quotation on request. Common questions: Regarding "Is it suitable for hazardous areas": Yes. The outputs are Ex ia rated for use in Zone 2 / Div. 2 or in the safe area on an appropriate backplane. Please contact us to confirm current pricing, availability and delivery for your required quantity; volume and project pricing are available on request.
