Note
The digital inputs of FL1D-H12RCC/FL1D-B12RCC are divided into
two groups, each consisting of four inputs. Within the same group,
all inputs must be operated on the same phase. Different phases
are only possible between the groups.
Example:
I1 to I4 on phase L1, I5 to I8 on phase L2.
Inputs within the FL1B-M08C2R2 may not be connected to differ-
ent phases.
Sensor connections
Connecting glow lamps and 2-wire proximity switches (Bero)
to FL1D-H12RCC/FL1D-B12RCC or FL1B-M08C2R2 (AC)
The figure below shows how you connect a switch with a
glow lamp to IDEC SmartRelay. The current that flows
through the glow lamp allows IDEC SmartRelay to detect a
“1” signal even though the switch contact is not closed. If,
however, you use a switch the glow lamp of which is fitted
with a power supply, this response does not occur.

Take into account the quiescent current of any 2-wire prox-
imity switches used into account. The level of the quiescent
current of some 2-wire proximity switches is high enough to
trigger a logical "1" signal at the IDEC SmartRelay input. You
should therefore compare the quiescent current of the prox
-
imity switches with the technical data of inputs Appendix A.
