New Lineup for Safety Applications
with Up to 12 Inputs
• Circuits for the required safety category are easy to build.
• The safety circuits you create can be registered as templates
and reused, for easy standardization.
• A wide range of TÜV-certified templates is also available.
• The NE0A operating conditions can be monitored from a
standard DeviceNet Master.
• Network distribution is possible by combining with an NE1A
Safety Controller.
• ISO13849-1 (PLe) and IEC 61508 SIL3 certification.

Ver. 1.0
Note: 1. The standard NE0A Safety Network Controller is equipped with spring-cage terminal blocks, but screw terminal blocks are available if
desired, e.g., to replace previous terminals.
2. Network Configurator version 2.1@ or higher must be used when using a NE0A-SCPU01 Safety Network Controller.
* When using the NE0A-SCPU01 as a standalone Controller, one input each is required for the feedback input and manual restart.
