Technical data

Wiring diagramm Operating data 24 V DC (18...32 V) 3
Operating voltage UB
EPD24-TB-101 Current rating IN fixed current ratings: 0.5, 1, 2, 3, 4, 6, 8, 10, 12 A
without signal input Closed current I0
with signal output F Staus indication by means of ON condition: typically 20...30 mA depending on signal output
(Single signal, N/O)
Operating condition: 13-14 closed Load circuit Green:
Fault condition: 13-14 open Load output unit is ON
Overload disconnection load circuit / Power-MOSFET is switched on
LINE+ 1 Short-circuit current IK
Trip time Orange:
14 in the event of overload or short circuit until electronic
13 disconnection

2 LOAD+ Red:
unit electronically disconnected
0V 3 load circuit/Power-MOSFET OFF
undervoltage (UB < 8 V)
after switch-on till the end of the delay period

OFF:
manually switched off or device is dead

potential-free auxiliary contact F

ON/OFF/ condition of switch

Power-MOSFET switching output (high slide switch)

typically 1.1 x IN (1.05...1.35 x IN)
active current limitation

see time/current characteristics

For electronic disconnection typically 3 s at ILoad > 1.1 x IN
Temperature disconnection typically 100 ms...3 s at ILoad > 1.8 x IN
(or 1.5 x IN/1.3 x IN, )

internal temperature monitoring with electronic disconnection

Low voltage monitoring load output with hysteresis, no reset required:
load »OFF« at UB< 8 V
Starting delay tStart
Disconnection of typically 0.5 sec after every switch-on and after applying UB
load circuit
electronic disconnection

Free-wheeling circuit suitable external free-wheeling circuit to be used with inductive
load

Several load outputs must not be connected in parallel
