POINT Guard Digital I/O Modules

ATTENTION:
• The safe state of the outputs is defined as the off state.
• The safe state of the module and its data is defined as the off state.
• Use the POINT Guard I/O module only in applications where the off state is the
safe state.
These are the safe states of the digital POINT Guard I/O modules:
• Safety outputs: OFF
• Safety input data to network: OFF (single channel and
dual-channel equivalent)
• Safety input data to network: OFF/ON for input channels n/n+1
(dual-channel complimentary)
