IIB intrinsically safe fieldbus power and signal repeater

MODULE ROLE
9122-IS-PS is the screw-terminal variant of Eaton MTL’s 9122-IS simplex FISCO power supply. It repeats a fieldbus signal from the host side to an intrinsically safe IIB segment and provides up to 256 mA output current.
CONFIGURATION NOTE
For 9122-IS-PS, Eaton’s ordering table identifies 9122-IS as the Gas Group IIB FISCO supply and -PS as the rising-cage screw-terminal version. The unit supports FOUNDATION Fieldbus H1 and PROFIBUS PA physical networks.

FAQ

Questions Buyers Ask Most

Can 9122-IS-PS be selected for an IIC fieldbus segment?+

9122-IS-PS is Eaton’s IIB FISCO variant; the 9121-IS family is listed for IIC. Match the hazardous-area classification and the certification of every fieldbus component before selection.

Which network role does 9122-IS-PS perform?+

9122-IS-PS supplies conditioned power to an intrinsically safe fieldbus segment and repeats the host-side signal. Eaton identifies FOUNDATION Fieldbus H1 and PROFIBUS PA physical networks for this family.

How should segment load be checked for 9122-IS-PS?+

9122-IS-PS provides up to 256 mA. Eaton describes support for up to 16 devices at 15 mA each; the actual segment design must account for device current and certified FISCO wiring/components.

What mounting and enclosure requirements apply to 9122-IS-PS?+

9122-IS-PS can mount on a 35 mm DIN rail or flat panel and is rated IP20. Eaton lists Zone 2 mounting, subject to the applicable certification, enclosure and site installation requirements.

Which termination settings matter when commissioning 9122-IS-PS?+

9122-IS-PS has a switch-selectable host-side terminator and a fixed terminator on the intrinsically safe side. Host-side power is also switch-selectable, so compare these settings with the segment design.

How does 9122-IS-PS differ from the -PC ordering option?+

9122-IS-PS uses pluggable screw terminals; Eaton lists 9122-IS-PC with spring-clamp terminals. The IIB power-supply family is otherwise identified by 9122-IS.

What should be confirmed before ordering 9122-IS-PS?+

9122-IS-PS specifies IIB FISCO service and screw terminals. Confirm the complete order number, hazardous-area certification, segment current budget and FOUNDATION Fieldbus H1 or PROFIBUS PA network requirements.
