Zelio Logic smart relays 0
Compact and modular smart relays
Zelio Logic smart relays are designed for use in small automated systems. They are
used in both industrial and commercial applications.
b For industry:
v automation of small finishing, production, assembly or packaging machines.
v decentralised automation of ancillary equipment of large and medium-sized
machines in the textile, plastics and materials processing sectors,
v automated systems for agricultural machinery (irrigation, pumping, greenhouses, ...).
b For the commercial/building sectors:
v automation of barriers, roller shutters, access control,
v automation of lighting installations,
v automation of compressors and air conditioning systems.
Their compact size and ease of setting-up make them a competitive alternative to
solutions based on cabled logic or specific cards.
Simple programming, ensured by the universal nature of LADDER and function block
diagram FBD (1) languages, meets all automation requirements and also the needs
of the electrician.
Compact smart relays are suitable for simple automated systems, up to 20 I/O.
If required, modular smart relays can be fitted with I/O extensions and a module for
communication on the Modbus network, for greater performance and flexibility, from
10 to 40 I/O.
Programming can be carried out:
b independently, using the buttons on the smart relay (ladder language),
b on a PC, using "Zelio Soft" software.
When using a PC, programming can be carried out either in LADDER language, or
in function block diagram language (FBD).
Backlighting of the display is programmable using “Zelio Soft” software and by direct
action on the smart relay's 6 programming buttons.
The Zelio Logic smart relay has a backup memory which allows programs to be
copied into another smart relay (examples: for building identical equipment, remote
transmission of updates).
The memory also allows a backup copy of the program to be saved prior to
exchanging the product.
When used with a smart relay without display or buttons, the copy of the program
contained in the cartridge is automatically transferred into the smart relay at power-
up.
Autonomous operating time of the clock, ensured by a lithium battery, is 10 years.
Data backup (preset values and current values) is provided by an EEPROM Flash
memory (10 years).
Zelio Logic smart relays can, if necessary, take the following I/O extensions:
b 6, 10 or 14 I/O, supplied with c 24 V via the smart relay,
b 6, 10 or 14 I/O, supplied with a 24 V via the smart relay,
b 6, 10 or 14 I/O, supplied with a 100... 240 V via the smart relay.
A module for communication on the Modbus network will be available for Zelio Logic
modular smart relays. It is supplied with
c 24 V via the smart relay.

Communication interface rr
The "communication" products in the Zelio Logic range include:
b a communication interface connected between a smart relay and a modem,
b analogue or GSM modems,
b “Zelio Soft Com” software.
They are designed for monitoring or remote control of machines or installations which
operate without personnel.
The communication interface, supplied with
c 12/24 V, allows messages, telephone
numbers and call conditions to be stored.
