Emerson DeltaV ™ S-series Traditional I/O

3.1 Analog input card

8-channel 4-20mA HART input card: supports 2/4-wire transmitters, with an accuracy of 0.1% and a resolution of 16 bits. Each channel is optically isolated and tested for a withstand voltage of 1500V DC. Supports transparent transmission of HART protocol, facilitating intelligent device management through AMS Device Manager. Optional 2.0A fuse.

16 channel 4-20mA HART input card (including Plus type): Provides higher channel density with an accuracy of 0.2%. The Plus card supports redundant configuration and can be used in conjunction with 48 pin large-scale terminal blocks.

8-channel RTD input card: supports 2/3/4 wire RTD (Pt100, Pt200, Pt500, Ni120, Cu10) and resistance measurement. Excitation current of 100 μ A, 16 bit resolution. User defined RTDs can be linearized with high precision using the Callendar Van Dusen equation.

8-channel thermocouple/mV input card: supports B, E, J, K, N, R, S, T-type thermocouples and millivolt signals. Channel grouping isolation, built-in cold junction compensation (CJC), extremely low open circuit detection current.

4-channel isolated input card: highly versatile, can be independently configured as multiple input types such as thermocouple, RTD, mV, V, etc. Both inter channel and inter channel systems achieve high voltage isolation up to 600V AC, suitable for complex situations with high common mode voltage or potential fluctuations.

3.2 Analog output card

8-channel 4-20mA HART output card: accuracy 0.25% (-40 to 60 ℃), resolution 14 bits, output load capacity up to 700 Ω @ 20mA. Supports HART transparent transmission, with optional fuses and redundant configurations.

16 channel 4-20mA HART output card (Plus type): high-density design, supports redundant configuration, suitable for large-scale analog output requirements.

3.3 Discrete input card

8/32 channel 24V DC dry contact input card: detects levels ON>2.2mA (8ch)/2mA (32ch), OFF<1mA (8ch)/0.25mA (32ch). Supports pulse counting function (up to 75Hz). When used in conjunction with large-scale terminal blocks, the 32 channel Plus card supports wire breakage detection function.

8-channel 24V DC isolated input card: The channels are isolated from each other, with a detection level of ON>10V and OFF<5V, and strong anti-interference ability.

4-channel pulse counting input card: supports input frequencies up to 50kHz, minimum pulse width of 10 μ s, 32-bit counter, suitable for high-speed counting or flow integration applications.

16 channel sequence of events (SOE) card: With a resolution of up to ± 0.25ms (inside the card), it is used to accurately record the sequence and time of switch events, and is a key tool for fault recall.

8-channel 120V AC input card: provides two types of dry contacts and isolation to meet the requirements of AC signal detection.

3.4 Discrete output card

8-channel 24V DC output card: provides two options: high side drive and isolated type. Each channel has a rated current of 1A and supports multiple output modes: discrete output, instantaneous output, and continuous pulse output (with a period of 100ms to 100s and a resolution of 5ms).

32 channel 24V DC high side output card (Plus type): 100mA per channel, total current 3.2A@24V When used in conjunction with large-scale terminal blocks, DC Plus cards support wire breakage detection function.

8-channel 120/230V AC output card: provides high side drive and isolation type, with 1A per channel, suitable for AC load control.

Redundancy and high availability

The redundant design of S series I/O aims to maximize system availability. Key components (such as specific models of AI, AO, DI, DO) can be installed on dedicated dual width redundant terminal blocks. The controller automatically scans and determines the main card. When a hardware failure, communication interruption, or field line failure is detected on the main card, the system automatically and undisturbed switches to the backup card within a maximum of two I/O bus scanning cycles. During the switching period, the analog output is driven by dual cards simultaneously for<5ms, ensuring no disturbance to the on-site actuator. The hardware alarm will automatically report the health status and switching events of the primary and backup cards, making it easier for operation and maintenance personnel to timely grasp the system status.

System compatibility and certification

The S series traditional I/O needs to be used in conjunction with SQ or SX series controllers and S series horizontal carriers. Starting from DeltaV v11.3.1, S-series and M-series controllers can coexist in the same control network. The Plus series cards require DeltaV software version v13.3 or higher. The S series I/O does not support vertical carrier, and vertical installation applications require electronic wiring technology with CHARMS I/O.

The product has passed CE, FM, CSA, ATEX, IECEx and multiple classification society certifications, and can be safely used in hazardous areas such as Class I Division 2 and Zone 2. All cards comply with ISA G3 corrosive gas standards.
