Omron, NE1A-SCPU

last update: December 19, 2013

• 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.
