Performance characteristics
Power supply
1)
Supply voltage 24 to 230 V
AC/DC
(-20% / +10%, 0/50/60 Hz)
Power consumption ≤ 4.9 VA / 2.4 W (20 mA); ≤ 5 VA / 2.5 W (22 mA)
Power loss ≤ 2 W (20 mA); ≤ 2.1 W (22 mA)
Current consumption at 24 V
DC
≤ 0.1 A (20 mA); ≤ 0.1 A (22 mA)
Current consumption at 230 V
AC
≤ 0.02 A (20 mA); ≤ 0.02 A (22 mA)
1) The data apply for the following operating scenario: input active / output active / output load 0 Ω. When
external voltages are connected to the output, the power loss in the device may increase. The power loss in
the device can be reduced by connecting an external output load.
Terminals A flat-blade screwdriver is required to establish an electrical connection to screw or push-
in terminals.
