IDEC SmartRelay Manual
4.1 Constants and connectors - Co
Constants and connectors (= Co) represent inputs, outputs,
markers and constant voltage levels (constants).
Inputs:
1) Digital inputs
Digital inputs are identified with an
I
. The number of the dig-
ital inputs (I1, I2, ...) corresponds to the number of the input
connectors of the IDEC SmartRelay Base and of the con-
nected digital modules, in the order of their installation. See
the following figure below.
2) Analog inputs
The IDEC SmartRelay versions FL1D-H12SND, FL1D-
H12RCE and FL1D-B12RCE are equipped with the inputs I7
and I8, which can also be programmed for use as
AI1
and
AI2
inputs. Signals at the I7 and I8 inputs are interpreted as
digital values, and those at the AI1 and AI2 inputs are inter-
preted as analog values. The inputs of a connected analog
module are numbered according to the already existing an-
alog inputs. Special functions the inputs of which should only
be connected to analog inputs are offered in programming
mode when you select the input signal, i.e. the analog inputs
AI1...AI8, Analog Memory Markers AM1...AM6, the block
numbers of a function with analog output.
