Special features of FL1E-H12RCE/FL1E-B12RCE and FL1E-H12SND
Fast inputs: I3, I4, I5 and I6:
These versions are also equipped with fast inputs (up/down
counters, frequency triggers). The restrictions mentioned
earlier do not apply to these fast inputs.
Note
The fast inputs I3, I4, I5 and I6 are the same as in the previous
versions FL1A to FL1D; therefore, a circuit program that is written
in these versions can be transferred to the new FL1E devices with
the programming software WindLGC, without any changes to these
features. The fast inputs have increased from 2 kHz to 5 kHz with
the FL1E series.
Expansion modules do not have fast inputs.
Analog inputs: I1 and I2, I7 and I8:
The inputs I1, I2, I7 and I8 of IDEC SmartRelay versions
FL1E-H12RCE/FL1E-B12RCE and FL1E-H12SND can be
used as either digital inputs or analog inputs. The input mode
is defined in the IDEC SmartRelay circuit program.
The inputs I1, I2, I7 and I8 provide digital inputs, and the
inputs AI3, AI4, AI1 and AI2 provide analog inputs, as
described in Chapter 4.1. AI3 corresponds to the input
terminal I1; AI4 corresponds to I2; AI1 corresponds to I7; AI2
corresponds to I8. The use of AI3 and AI4 is optional. You
configure your IDEC SmartRelay to use either two or four
analog inputs as described in section 5.2.4.
When using inputs I1, I2, I7 and I8 as analog inputs, only the
range from 0 to 10 V DC is available.
Connecting a potentiometer to inputs I1, I2, I7 and I8
To allow you to achieve 10 V as the maximum value when
you completely turn the potentiometer once, you must
connect a series resistor on the potentiometer’s input side
regardless of the input voltage (see figure below).
We suggest the following sizes of potentiometers and
associated series resistors:
