■
Devices with Mechanical Contact Outputs
Examples: Emergency stop buttons and safety limit switches
These devices use both a safety input terminal and test output terminal. A
safety input terminal inputs the test output signal (pulse output) of the NE1A-
series Controller via a contact output device.
■
Devices with PNP Semiconductor Outputs (Current Sourcing)
Example: Light curtains
A PNP semiconductor output signal from this type of device is input to the
NE1A-series Controller’s safety input terminal.
