IDEC SmartRelay functions
4.1 Constants and connectors
Note
To avoid that the IDEC SmartRelay Base Module fails to read input signals because its
built-in MCU (Microcontroller Unit) is too sensitive and runs much faster than those in
previous IDEC SmartRelay devices, an on-/off-delay function is designed for IDEC
SmartRelay:

•
Besides, when the Base Module is in slave mode, a 5 ms on-delay time and a 100 ms
signal-retentive-time are defined for all the digital inputs.
•
Analog inputs
The IDEC SmartRelay versions FL1F-H12SCD, FL1F-H12RCE and FL1F-B12RCE have
the inputs I1, I2, I7 and I8, which you can also program for use as AI3, AI4, AI1 and AI2
inputs. As described in topic "Setting the number of AIs in IDEC SmartRelay (Page 264)",
you can configure these modules to use either two analog inputs (AI1 and AI2), or all four.
IDEC SmartRelay interprets signals at the I1, I2, I7 and I8 inputs as digital values, and
those at the AI3, AI4, AI1 and AI2 inputs as analog values. Note that AI3 corresponds to I1
and AI4 corresponds to I2. This numbering preserves the previous correspondence of AI1
to I7 and AI2 to I8 that was available with the FL1D series. IDEC SmartRelay numbers the
inputs of a connected analog module according to the already existing analog inputs. See
topic "Maximum setup with expansion modules (Page 17)" for example setups. In
programming mode, when you select the input signal of a special function that takes an
analog input, IDEC SmartRelay offers the analog inputs AI1 to AI8, analog memory
markers AM1 to AM64, analog outputs AQ1 to AQ8, and the block numbers of functions
with analog outputs.
Outputs
•
Digital outputs
Digital outputs begin with the letter Q. The output numbers (Q1, Q2, ... Q20) correspond
with the numbers of the output connectors at the IDEC SmartRelay Base Module and with
those of the expansion modules, in their order of installation.
IDEC SmartRelay FL1F also provides 64 blank outputs and identifies them with the letter
x. You cannot reuse the blank outputs in a circuit program. The blank outputs differ from
memory markers, for example, which you can reuse. A blank output, for example, is useful
for the special function Message texts (Page 196), if only the message text is of
significance to a circuit program.
•
Analog outputs
Analog outputs begin with the letters AQ. Eight analog outputs are available, namely AQ1,
AQ2,... AQ8. You can only connect an analog output with the analog input of a function, an
analog memory marker AM or an analog output connector.

For FL1F-H12RCC and FL1F-B12RCC, a 25 ms on-delay time and a 20 ms off-delay
time are defined for digital inputs I1 to I8.
For all the other IDEC SmartRelay versions, a 5 ms on-delay time and a 5 ms off-delay
time are defined for all the digital inputs.
