The M-series Fieldbus H1 Carrier connects your field-mounted discrete I/O to your fieldbus segment and substantially reduces the wiring and associated costs that are typical of the fieldbus architecture. The carrier is programmed to accept DeltaV™ Classic I/O discrete signals and transmit the signals over the fieldbus segment to the controller. Use the DeltaV M-series Fieldbus H1 Carrier as remote I/O to bring in 16 signals on one segment, thereby greatly reducing costs.
