Specifications
The Safe Disable circuit consists of two independent hardware input channels that can block the output transistors. It
provides a stop function in compliance with "Safe Torque Off" as defined in the IEC/EN 61800-5-2. Safe Disable inputs
have been designed to meet the requirements of the ISO/EN 13849-1 and IEC/EN 61508.
