The ET 200SP failsafe relay modules have been redesigned after Siemens completed a global exchange with users from all industries. The revamped modules are the first to support the “No DIP” concept, eliminating the need to set PROFIsafe address assignment via DIP switches. They also provide a relay output with two safety relays.
Several features and functions have been added. The line is designed for switching of external voltages and for applications where switching power requirements are greater than 2A or where voltage levels exceed 24V.
The ET 200SP simplifies installation by using push-in clamping technology that facilitate the wiring and disconnecting of cables, enabling tool-free wiring. The modules are also well suited for environments that require galvanically isolated contacts.
Instead of using DIP switches, the two safety relays can be activate via an external failsafe electronic module such as the 4 F-DQ module. Dedicated terminals are provided to make this a simple task.
