Safety Network Controller
NE1A-SCPU Series
CSM_NE1A-SCPU_Series_DS_E_6_4
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.
