4.1 Constants and Connectors - Co
Constants and connectors (connectors = Co) are inputs,
outputs, memory markers and fixed voltage levels
(constants).
Inputs
Inputs are identified by the letter I. The input numbers (I1,
I2, ...) correspond to the numbers of the input connectors
on IDEC SmartRelay.
Analog inputs
The IDEC SmartRelay models FL1A-H12SND, FL1A-
H12RCE and FL1A-B12RCE include the inputs I7 and I8,
which can also be used as AI1 and AI2, depending on how
they are programmed. If the inputs are used as I7 and I8,
the signal applied is interpreted as a digital value. If they
are used as AI1 and AI2, the signals are interpreted as
analog values. In the case of special functions, which can
only be effectively connected with analog inputs on the
input side, only the analog inputs AI1 and AI2 are offered
for selection in programming mode when the input signal is
selected.
Outputs
Outputs are identified by the letter Q. The output numbers
(Q1, Q2, ...) correspond to the numbers of the output
connectors on IDEC SmartRelay.
