IDEC SmartRelay installation and wiring
38 IDEC SmartRelay Manual 
When using a potentiometer and 10 V input voltage as the
maximum value, you must ensure that with a connected
input voltage of 24 V, 14 V must release via the series
resistor so that a maximum of 10 V are supplied when you
turn the potentiometer one full rotation. With a voltage of 
12 V, this can be neglected.
Note
The FL1B-J2B2 expansion module provides additional analog
inputs.
Always use twisted and shielded cables for analog signals, and
keep these as short as possible.
Sensor connections
To connect sensors to IDEC SmartRelay :
FL1E-H12RCA / FL1E-B12RCA / FL1E-H12RCE / FL1E-B12RCE /
FL1E-H12SND
FL1E-H12RCC / FL1E-B12RCC
!
Warning
Current safety regulations (VDE 0110, ... and IEC 61131-2, ... as
well as cULus) do not permit the connection of different phases to
an AC input group (I1 to I4 or I5 to I8) or to the inputs of a digital
module.

The inputs of these devices are not
isolated and therefore require a
common reference potential (chassis
ground ).
With FL1E-H12RCE / FL1E-B12RCE
and FL1E-H12SND modules, you can
tap analog signals between the
supply voltage and chassis ground
(* = series resistor with 24 V DC).
On the FL1E-H12RCA/-B12RCA, P1 and P2
are indicated in place of L+ and M, respectively

The inputs of these devices are
arranged in 2 groups, each
consisting of 4 inputs. Different
phases are only possible between
blocks, but not within the blocks.
