Core functions:
Redundancy design: This unit adopts a dual-redundancy structure. Even if one module fails, the system can still operate normally and ensure uninterrupted factory safety.
Node expansion: S2SC70D supports connecting up to 32 N-IO nodes or 13 safety node units (SNB10D) to expand the number of I/O channels.
Application fields: Widely used in industries with extremely high safety requirements such as oil and gas, power, petrochemicals, chemicals, and pharmaceuticals.
Compliance: Designed in accordance with global safety standards, including IEC 61508, which is typically used in systems achieving SIL3 safety level.
