SRTC - 3NO/1NC Extensionmodule - safety module

        

 

With the help of the SREC and SRTC extension relays coupled with any basic device of the ZANDER SR series, up to 3 additional and time delayed safety contacts can be obtained per device.

In this way, an existing system can be modularly extended in practically any manner.
