Datasheet

Type of outputs connection Connection of all outputs after ramp-up of the supply voltage > 20
V; delay time of 25 ms, 200 ms, 500 ms or "load-optimized" can
be set via DIP switch for sequential connection
Efficiency
Efficiency in percent 99%
Power loss [W] / at rated output current / for rated
value of the output current / typical
15W
Switch-off characteristic per output
Switching characteristic
● of the excess current
Iout = 1.0 ...1.5 x set value, switch-off after approx. 5 s
● of the current limitation
Iout = 1.5 x set value, switch-off after typ. 1 s
● of the immediate switch-off
Iout > set value and Vin < 20 V, switch-off after approx. 8 ms
Design of the reset device/resetting mechanism via sensor per output
Remote reset function Non-electrically isolated 24 V input (signal level "high" at > 15 V)
Protection and monitoring
Fuse protection type / at input 20 A fast per output (not accessible)
Display version / for normal operation Three-color LED per output: green LED for "Output switched
through"; orange LED for "Output switched off manually"; red LED
for "Output switched off due to overcurrent"
Design of the switching contact / for signaling
function
Floating status signal output (pulse/pause signal that can be
evaluated via SIMATIC function block)
Safety
Galvanic isolation / between input and output at
switch-off
No
