IDEC SmartRelay installation and wiring
IDEC SmartRelay Manual 21
With any setup, you can plug in an analog output module,
which has the maximum of two analog outputs.
For FL1E-H12RCE/FL1E-B12RCE and FL1E-H12SND
modules
, you can configure whether the module uses two or
four of the four possible analog inputs. AI inputs are
numbered consecutively depending on how many you
configure the base module to use. If you configure two
inputs, they are numbered AI1 and AI2, and correspond to
the I7 and I8 input terminals. Subsequent AI expansions
modules would begin numbering at AI3. If you configure four
inputs, they are numbered AI1, AI2, AI3, and AI4, and
correspond to I7, I8, I1, and I2 in that order. Subsequent AI
expansions modules would begin numbering at AI5. See
sections 4.1 and 5.2.4.
High-speed/optimal communication performance
For optimal and high-speed communication performance
be
tween IDEC Smar
tRelay base module and the various
modules, we recommend that you install the digital modules
first, then the analog modules (examples above). (The
special function PI controller is an exception: the AI used for
the value PV should be on the IDEC SmartRelay base
module or an analog input module adjacent to the IDEC
SmartRelay base module).
We recommend that yo
u position the CM AS Interface on
the far right-hand side. (If the AS Interface voltage fails,
communication between the IDEC SmartRelay system and
expansion modules that are arranged to the right of the IDEC
SmartRelay CM AS Interface expansion module is
interrupted).
The Text Display module is installed separ
ately. You
connect it to the IDEC SmartRelay base module with the
included Text Display cable.
