NE0A-SCPU01
Safety Network Controller NE1A-SCPU Series 117
Safety Network Controller
NE1A-SCPU Series
Achieve Safety Control through
Programming.
• Compact Safety Controller.
• The NE1A-SCPU01-V1 provides 16 built-in safety inputs and 8 built-
in safety outputs.
The NE1A-SCPU02 provides 40 built-in safety inputs and 8 built-in
safety outputs.
• Reduced wiring with safety networks. Connect up to 32 Safety
Terminals.
• Monitor the safety system from Standard Controllers across the
network.
• ISO13849-1 (PLe) and IEC 61508 SIL3 certification.
Ordering Information
Note: The standard NE1A Controllers are equipped with spring-cage terminal blocks, but other screw terminal blocks are available if desired, e.g., to replace previous terminals.
