Key Functional Safety Features
-
SIL3 Compliance: The DX581-S (1SAP284100R0001) supports dual-channel evaluation of sensors, enabling SIL3 safety functions such as emergency stops and light curtains.
-
Integrated Test Pulses: Four dedicated pulse outputs allow the system to detect short circuits to external voltage or crosstalk between input lines, ensuring loop integrity.
-
Advanced Diagnostics: Real-time monitoring of output voltage and current allows the module to detect wire breaks or internal hardware failures instantly.
-
Versatile Configuration: Part of the AC500-S range, this module can be mixed with non-safety I/O on the same bus, allowing for cost-effective system scaling.
