All S500 I/O modules comply to SIL3 (IEC 61508, IEC 62061, IEC 61511) and PL e (ISO 13849-1) functional safety standards. These modules can be used centrally as well as in the remote rack via PROFINET network using PROFIsafe protocol.
Digital Input Module DI581-S
- 16 safety digital input channels up to SIL2 or PL d / 8 channels up to SIL3 or PL e with 8 test pulse outputs.
- Field cable length up to 1000 m supported.
- All channels (including test pulse outputs) are protected against reverse polarity, reverse supply, short circuit and continuous overvoltage up to 30 V DC.
Digital Input/Output Module DX581-S
- 8 safety digital output channels up to SIL3 or PL e and 8 safety digital input channels up to SIL2 or PL d / 4 channels up to SIL3 or PL e with 4 test pulse outputs.
- Field cable length up to 1000 m supported.
- All channels (including test pulse outputs) are protected against reverse polarity, reverse supply, short circuit and continuous overvoltage up to 30 V DC.
Analog Input Module AI581-S
