112 Safety Network Controller NE0A-SCPU01
Safety Network Controller
NE0A-SCPU01
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.
• 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.
Ordering Information
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.
Note 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.

Functions
The following function blocks are available for designing safety circuits with the NE0A-SCPU01.
These function blocks can be selected and assembled using the interactive wizard format to efficiently design safety applications.
Note: There is a possibility that safety cannot be maintained when an OR part or an AND/OR part is selected for input logic, or an OR/AND part is selected for output logic. Sufficiently
confirm safety prior to use.
Classification of function block
