Taps create nodes in the GuardLink circuit. A safety device is connected to
each tap. Two types of taps are available:
• Taps that interface with devices having voltage-free safety contacts
• Taps that interface with devices that have OSSD signals
Each type is available in an 8-pin and 5-pin device connection version.
The taps are intended to be mounted on the machine, near the location of the
device it monitors. The different types and versions can be connected in any
order and can be mixed.
