Product Description
The S2CP471-01 is a high-integrity central processor designed for Yokogawa ProSafe-RS Safety Instrumented System (SIS). It is engineered for Safety Integrity Level 3 (SIL3) applications, providing the rigorous logic execution required for emergency shutdown (ESD), fire & gas (F&G) systems, and burner management.
Optimized for SSC60 and S2SC70 safety control units, the module features a dual-microprocessor architecture with continuous internal cross-checking. It supports dual-redundant bumpless failover and integrates seamlessly with CENTUM VP DCS networks via Vnet/IP. This variant includes ISA G3 conformal coating for reliable operation in corrosive industrial environments.

Installation & Maintenance Notes
-
Compatibility: Requires ProSafe-RS R3.01 or later (R4.01+ for S2SC70 mounting).
-
Migration Support: Can replace legacy SCP461 modules; replacement must be performed by Yokogawa-authorized personnel to maintain safety integrity.
-
Firmware: Ensure the latest software patches are applied for CENTUM VP / ProSafe-RS co-existence.
Frequently Asked Questions
Q: Can S2CP471-01 coexist with SCP461 in the same redundant pair?
A: No. In duplexed configurations, both modules must be identical. Mixing S2CP471-01 and SCP461 is not supported.
Q: What is the significance of the ISA G3 rating?
A: The G3 rating means the PCB is treated with conformal coating to resist corrosion from sulfur, chlorine, or other reactive gases.
Q: Is the battery replaceable while the system is online?
A: Yes. The S9450FE battery can be replaced while powered, provided the system is redundant to prevent data loss.
