Static monitoring of STO feedback at start-up is sufficient for the converters FSH and FSJ.
Modular 3RK3 safety system
You can use the following outputs to control the failsafe digital inputs in the converter:
● The failsafe digital outputs in the central units of the 3RK3 modular safety system
● The failsafe digital outputs in the EM 2/4F-DI 2F-DO expansion module
● The failsafe digital outputs in the EM 4F-DO expansion module.
● The failsafe relay outputs in the EM 4/8F-RO expansion module
● 2 individual relay contacts of the EM 2/4F-DI 1/2F-RO expansion module
