DeltaV S-series I/O hardware is designed for quick installation.
The I/O interface, sometimes called the I/O subsystem, consists of terminal blocks that clip onto the carrier to provide terminations for field wiring and the I/O cards that snap onto the terminal blocks. The I/O cards convert field signals to the appropriate format for control and communications.
The DeltaV S-series I/O interface consists of multiple types of I/O cards including analog and discrete input and output cards, HART input and output cards, Thermocouple / mV input, RTD / Resistance input, isolated, and pulse count input cards, serial cards, and Sequence of Events cards. Bus cards such as the Fieldbus H1, Profibus DP, AS-Interface, and DeviceNet are also supported. A single I/O subsystem supports up to 64 I/O cards.
DeltaV S-series Plus cards are redundant high-density cards for AI and AO HART, DI, DO, and fieldbus signals.
The following S-series and S-series Plus cards support simplex or redundant applications:
