8-Channel Fail-Safe Digital Input Module:Provides 8 configurable safety-related digital inputs for connecting emergency stops, safety door switches, light curtains, and other safety devices.
Complies with International Safety Standards:Meets IEC 61508, EN 62061, and ISO 13849-1, enabling implementation of safety systems up to SIL2/SIL3 or PL d/e performance levels.
Redundant Dual-Channel Signal Evaluation (1oo2):Uses dual-channel input acquisition with cross-checking to reliably detect wire breaks, short circuits, and other failures, ensuring signal integrity.
Designed for Fail-Safe Automation Systems (F-System):Must be used with S7-300F F-CPUs (e.g., CPU 315F-2 PN/DP or CPU 317F-2 PN/DP) and communicates via F-Communication protocol for secure data transfer.
Hot-Swap Capability (in Redundant Setups):Supports online replacement in redundant configurations, ensuring high availability and uninterrupted operation of critical safety functions.
