Carrier width accepts eight I/O cards. Backplane current capacity is 8 A maximum to I/O cards. Bussed field-power bus capacity is 6.5 A maximum. Control-network interface uses redundant RJ-45 primary and secondary connections at 10/100 Mbps where fitted. Operating temperature is -40 to 70°C. Storage temperature is -40 to 85°C. Relative humidity is 5 to 95% noncondensing. Conformal coating is ISA-S71.04 G3. Carrier dimensions from Emerson M-series data are 16.5 cm height, 33.6 cm width, and 3.1 cm depth.

Carrier shield bar for EMI reduction, keyed module slots to prevent incorrect insertion, redundant control-network connections, hot-swap support for compatible I/O cards, and hazardous-area certification options.

The shield bar reduces electromagnetic interference across mounted I/O modules. Keyed slots prevent incorrect module insertion. Redundant network connections support primary and secondary DeltaV communications. Compatible I/O cards can be replaced under power according to Emerson procedures.

DeltaV process automation in refineries, chemical plants, power plants, oil and gas facilities, water and wastewater treatment, and Zone 2 or Class I Division 2 installations using M-series I/O.

Eight I/O slots allow high-density signal integration. Backplane power supports multiple analog, digital, HART, and specialty I/O modules within the 8 A backplane and 6.5 A field-power limits. Network performance depends on DeltaV controller and I/O card type.

Coated metal carrier frame, printed backplane, shielded connector blocks, and G3-conformal-coated circuit areas where specified. Shield bar uses conductive structural material for EMI bonding.

Horizontal eight-wide carrier with I/O card slots, terminal-block positions, carrier shield bar, control-network ports, power connection points, and keying mechanisms. It can be extended with carrier extender cables for larger I/O groups.

The carrier distributes 12 V or system power, field power, and DeltaV backplane communication to each installed I/O module. I/O modules convert field signals and exchange digital process data with the DeltaV controller through the carrier backplane and control network.

Mount in a suitable DeltaV cabinet or horizontal carrier assembly with adequate ventilation. Connect system power and field power within rated current limits. Install network cables with proper grounding and shielding. Follow hazardous-area instructions for ATEX, IECEx, or UL Class I Division 2 deployment.

Use only M-series I/O cards compatible with the slot keying. Do not exceed 8 A backplane or 6.5 A field-power ratings. Verify redundant network addressing before hot-swap. Inspect conformal coating and shield-bar grounding during maintenance.
