SIEMENS SITOP SEL1200 SELECTIVITY MODULE 8 *10A 6EP44387FB003DX0
SITOP SEL1200 8-channel selective module switching characteristic input: DC 24 V/60 A output: DC 24 V/8 x 10 A settable threshold value 2 ... 10 A with monitoring interface.
General information:
Input
shape of the electrical network Regulated DC voltage
supply voltage with DC rated value 24 V
input voltage with DC 20.4 ... 30 Voverloadability for overvoltage 35 V
input current with nominal value of the input voltage
24 V nominal value 60 A
Output
shape of the voltage curve at the output Regulated DC voltage
formula for output voltage Ue - approx. 0.2 V
overall relative voltage tolerance known Corresponding to the input supply voltage number of outputs 8
output current up to 60 °C for each output rated value 10 A; +60 ... +70 °C: Derating 2%/K settable trip value for current-dependent overload release current 2 ... 10 A
type of trip value setting Via potentiometer
characteristic of the product parallel connection of outputs Yes
type of activation of the outputs Activation of all outputs when the steady state value of the
supply voltage > 20 V is reached, delay time of 25 ms, 200 ms, 500 ms or can be set via DIP switch for "load-optimized" sequential switching
Efficiency
efficiency [%] 98 %
power dissipation [W] at nominal value of the
output voltage at nominal value of the output current typ. 18 W
Switch-off characteristic for each output
switching characteristic
● of overcurrent shutdown IA > 2.0 x set value, switch-off after approx. 30 ms, IA > 1.8 x set
value, switches off after approx. 0.1 s, IA > 1.5 x set value,
switch-off after approx. 1 s, IA > 1.0 x set value, switches off after approx. 5 s
● of immediate switch-off IA > set value and Ue < 20 V, switch-off after approx. 8 ms execution of reset via button for each output remote RESET function 24 V input non-floating (signal level " high" with > 15 V)
Protection and monitoring
performing protection on the 16 A input for each output (not accessible) performing the display for normal operation Tricolor LED for each output: green LED for "Output switched on", yellow LED for "Output manually switched off", red LED for "Output switched off due to overcurrent" execution of the switching contact for signaling function. Status signal output or floating cumulative signaling contact (pause/pulse signal selectable from the Simatic function block).
