Features
The AR/2A output module provides 8 floating contact assemblies for a rated
current of 2 A. The AR/2A meets the requirements of Protective Separation
for overvoltage class (ÜK) II, as per EN 50178. Voltages belonging to over-
voltage class III may be connected on a given 4-conductor terminal only pro-
vided that voltage potentials are effectively separated by a vacant terminal
between connections.
