Fail-safe digital inputs/outputs with IP65/66/67 degree of protection for application on the machine level without control cabinet

Fail-safe digital inputs

• For fail-safe reading of sensor information (1 or 2 channels)
• Provide integral discrepancy evaluation for 2-out-of-2 signals
• Internal sensor supplies (incl. test function) available

Fail-safe digital outputs

• Fail-safe 2-channel activation (sink/source output) by actuators
• Actuators can be driven by up to 2 A

All modules are certified up to SIL 3 (IEC 61508) and feature detailed diagnostics.

The modules support PROFIsafe, both in PROFIBUS, and in PROFINET configurations. They can be used with IM151-7 F-CPU, CPU31xF-2 DP, CPU31xF-2 PN/DP and CPU416F-2.
