Overview
The NE1A-SCPU01(-V1) is equipped with 16 safety input terminals.
The NE1A-SCPU02 is equipped with 40 safety input terminals.
By selecting the setup and wiring based on the types of input devices to be
connected or the safety level to be achieved, the NE1A-series Controller can
flexibly handle various applications. For example, an NE1A-series Controller’s
safety inputs can be used as described below.
Connecting to Contact Output Safety Devices
The NE1A-series Controller’s test output signal (a pulse output) is input by
connecting to a contact output device. Input signal line errors can then be
detected by inputting the test output signal.
• Short circuits to the power supply line (positive side)
• Earth faults
• Short circuits between input signals
Connecting Semiconductor Output Safety Devices
The output from a 24-VDC semiconductor, such as the OSSD output from a
Light Curtain, is input. Errors in the OSSD output signal line (i.e., the NE1A-
series Controller’s input signal line) is detected at the external connection
device.
