2. Key Selling PointsFail-Safe Digital Input Module:Provides 8 safety-related digital inputs, compliant with functional safety standards such as IEC 61508 and EN 62061, suitable for SIL2/SIL3 or PL d/e safety applications. Redundant Dual-Channel Input Architecture (1oo2):Each safety input uses a dual-channel design with redundant wiring,
enabling reliable fault detection (e.g., wire break, short circuit)
through cross-checking. Compatible with Standard & Safety Signals:Capable of processing both standard and fail-safe digital signals,
offering flexibility in mixed safety and non-safety control
environments. Designed for Fail-Safe Automation Systems:Must be used with an F-CPU (e.g., CPU 317F-2 PN/DP) and communicates via PROFIBUS-FMS or PROFINET F-Communication for secure data transmission. High Noise Immunity & Electrical Isolation:Features robust electromagnetic compatibility (EMC) and galvanic
isolation between input channels and backplane bus, enhancing
system reliability.
