Getting started with IDEC SmartRelay
It's your choice
The various IDEC SmartRelay Base versions, expansion
modules, Text Display and communication modules offer
you a highly flexible and adaptive system to suit your specific
tasks.
The IDEC SmartRelay system offers you many solutions
such as for small domestic installations, simple automation
tasks, and even complex engineering tasks involving its
integration into a bus system (e.g. communication module
AS interface).
Note
IDEC SmartRelay base module may only be equipped with
expansion modules of the same voltage class. Mechanical
encoding pins in the housing prevent you from connecting devices
of a different voltage class.
Exception: The left-hand interface of an analog module or
communication module is galvanically isolated.
This type of expansion module can therefore be connected to
devices of a different voltage class. See also Chapter 2.1.
A Text Display, if used, can be connected only to an FL1E IDEC
SmartRelay base module.
Each IDEC SmartRelay base module supports the following
connections for the creation of the circuit program, regardless of the
number of connected modules:
• Inputs 11 to I24
• Analog inputs AI1 to AI8
• Outputs Q1 to Q16
• Analog outputs AQ1 and AQ2
• Memory Markers M1 to M27:
- M8: Startup marker
- M25: Backlight flag: IDEC SmartRelay Display
- M26: Backlight flag: Text Display
- M27: Message text character set flag
• Analog Memory Markers AM1 to AM6
• Shift register bits S1 to S8
• 4 cursor keys
• 16 blank outputs X1 to X16
