3.36 Relay output module SM 322; DO 8 x Rel. AC 230 V/5 A; (6ES7322-1HF10-0AA0)
Operation on safety extra-low voltage (SELV)
Make allowances for the special feature outlined below when operating relay output module
322-1HF10 on SELV:
To operate a terminal on SELV, the horizontally adjacent terminal may not be operated at a
rated voltage higher than 120 VUC. The creepage distances and air gaps of the 40-pin front
connector do not meet SIMATIC requirements in terms of safe electrical separation if
operated with voltages above 120 VUC.
