Yokogawa SAI143-H63/PRP S3 16 channel analog input module

Yokogawa SAI143-H63/PRP S3 16 channel analog input module

Yokogawa SAI143-H63/PRP S3 is a 16 channel analog input module with HART protocol for Yokogawa ProSafe-RS Safety Instrumented System (SIS), and PRP represents support for redundant module configuration. SAI143-H63/PRP S3 is responsible for collecting on-site 4-20mA two-wire transmitter signals (pressure, temperature, flow, etc. instruments), completing signal isolation, analog-to-digital conversion, and uploading process measurement values to the safety controller; The HART channel supports bidirectional communication with smart transmitters to read instrument diagnostic information. Support dual redundant hot standby operation for safety interlock circuits, ensuring the safety protection function of chemical and oil and gas equipment.

We are a trading enterprise specializing in the supply of spare parts for industrial automation control systems, with a long-term focus on manufacturing and energy infrastructure. Relying on a spare parts resource network covering the four core systems of PLC, DCS, robots, and servo drives, we provide customers with the supply of discontinued spare parts, functional modules, control cards, and drive devices, helping them solve the pain points of difficulty in purchasing discontinued parts, long delivery times, and high risks, and ensuring the operation of production lines.

Parameter Specifications

Yokogawa SAI143-H63/PRP S3 16 channel analog input module

Product features

1. 16 channel 4-20mA analog acquisition, built-in HART communication, capable of remote parameter reading and writing, instrument self-test diagnosis for on-site intelligent transmitters.
2. Support module dual redundancy (PRP) configuration, with standby modules switching without disturbance in case of main module failure, ensuring uninterrupted operation of the safety circuit.
3. Module level electrical isolation, isolating the on-site side from the system side, suppressing ground loop interference, and protecting the SIS controller from on-site surge impact.
4. SIL3 safety certification, meeting the functional safety standards of safety instrumented systems, used for emergency parking and safety interlock circuits.
5. Support two-wire transmitter power supply, the module directly supplies power to on-site instruments without the need for additional on-site power supply.
6. High precision acquisition, low-temperature float design, maintaining measurement stability in the temperature fluctuation environment of the process site.
7. Independent channel fault diagnosis, capable of detecting faults such as wire breakage, short circuit, and over limit, and uploading alarm information to the SIS system.
8. Rack plug-in structure, supports online hot replacement, and does not require shutdown during maintenance, reducing the risk of device shutdown.
9. Adapt to the ProSafe RS safety system backplane and seamlessly integrate with the SCS safety controller to build a complete safety protection system.
