REL-OR3/LDP-24DC/3X21 - Single relay
2903693
Plug-in octal relays with power contacts, 3 changeover contacts, test button, freewheeling diode, mechanical switching position indicator, polarity: A1+, A2-, input voltage: 24 V DC
Notes on operation The outputs are not suitable for switching different outer conductors.
Notes on operation Do not use to separate SELV / PELV circuits from other circuits, because safe isolation is not guaranteed.
