IDEC SmartRelay functions
IDEC SmartRelay Manual 93
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 with the number of the in-
put connectors of the IDEC SmartRelay Basic and of the
connected digital modules, in the order of their installation.
See the following figure.
2) Analog inputs
The IDEC SmartRelay versions FL1C-H12SND, FL1C-
H12RCE and FL1C-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 whose inputs 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.
Outputs:
1) Digital outputs
Digital outputs are identified by the character Q. The output
numbers (Q1, Q2, ... Q16) correspond with the numbers of
the output connectors at the IDEC SmartRelay Basic and
with those of the expansion modules, in their order of instal-
lation. See the following figure.
