Supply voltage (SELV)
(1)
(2)
(1) To meet the requirements of the relevant product standards (for example, EN 61496-1), the external voltage supply for the
device must be able to bridge a brief mains failure of 20 ms. Power supplies according to EN 60204-1 satisfy this requirement.
Suitable power supplies are available as accessories from Rockwell Automation.
(2) Operation only in a short-circuit protected system with max. 8 A
16.8…30 V (24V, typical)
Permissible residual ripple
