Disconnection of the load circuit
- Manually at the device via the
ON/OFF button
- after an overload / short circuit
disconnection with saving (no automatic
reset)
- temporarily in case of low voltage
- with no operating voltage
Switching on the load circuit
- ON/OFF button Device can only be switched on when
operating voltage is applied
- Applying the The device starts operation

REX12D-TE2-100-DC24V-xA-xA-E 2-channel
The REX12-TAx-E is operated at the EM12-T-E in standard mode.
The REX12D-TE2-E can be operated at the EM12D-T as well as
at the EM12-T-E. The operating mode EM12D-T (COM-Mode) or
the EM12-T-E (standard mode) is recognized automatically.
The following indications refer exclusively to the standard mode.
