Emerson S-series Mass Connection Solutions

（2） Key functional characteristics

Signal adaptation and connection flexibility:

Analog Channel: Supports 4-20mA HART signals, and 2-wire/4-wire devices can independently select wiring methods according to channels to meet different on-site instrument requirements.

Discrete channel: DI supports 24V DC dry contacts and isolation signals, DO supports 24V DC high side output and no voltage contacts, fuse position can be switched by jumper to output types, suitable for various discrete devices.

Maintenance convenience:

Circuit disconnection: The blade type disconnection design of the AI/AO board can be directly connected to the testing equipment, and the replaceable fuse of the DI/DO board is convenient for cutting off the on-site power supply without interrupting the overall process.

Status indication: The yellow LED displays the real-time on/off status of discrete channels, which can quickly locate the problematic channel in case of a fault and simplify the troubleshooting process.

Fault detection and safety design:

The terminal fault detection function of DI/DO Plus board, combined with Plus I/O card, can monitor the power and cable status in real time. When abnormal, the diagnostic system automatically marks it, reducing the time for troubleshooting.

Onboard isolation design: DI board on-site wiring and I/O card circuit optical isolation (1000VDC test for 2 seconds), DO board relay contacts are isolated from the system (250V AC, 3600VDC test) to ensure system safety.

（3） System compatibility

I/O card adaptation: Only supports DeltaV S series traditional I/O cards, including single redundant/redundant 32 channel DI/DO cards, 16 channel AI/AO Plus cards, which need to be ordered together with the connection board (refer to the "S Series Traditional I/O Product Manual" to confirm the model).

Software requirements: The fault detection function needs to be paired with the DeltaV diagnostic system, and the I/O card parameter configuration is completed in the DeltaV resource manager. There are no additional software version requirements (compatible with mainstream DeltaV versions).
