3.35 Relay output module SM 322; DO 8 x Rel. 230VAC/5A; (6ES7322-5HF00-0AB0)
Operation on safety extra-low voltage (SELV)
Make allowances for the special feature outlined below when operating the
6ES7322-5HF00-0AB0 relay output module on SELV:
The horizontally adjacent terminal of a terminal operated on SELV may not be operated at a
rated voltage higher than 120 VUC. When operated at voltages higher than 120 VUC, the
creepage distances and air gaps in the 40-pin front connector do not meet SIMATIC
requirements of safe electrical separation.
