IDEC SmartRelay memory
and battery cartridge (card)
IDEC SmartRelay provides the following cartridges for
program storage and real-time clock backup:
• IDEC SmartRelay Memory cartridge
• IDEC SmartRelay Battery cartridge
• IDEC SmartRelay Memory/Battery cartridge
Each of the three cartridges is color-coded to make them easily
distinguishable from one another. They also vary in size. The
IDEC SmartRelay Memory cartridge (purple) provides storage
for the circuit program. The IDEC SmartRelay Battery cartridge
(green) provides battery backup of the real-time clock for up to
two years. The IDEC SmartRelay Memory/Battery cartridge
(dark brown) provides both circuit program storage and
battery backup of the real-time clock.
The FL1E IDEC SmartRelay Memory cartridge and the FL1E
IDEC SmartRelay Memory/Battery cartridge provide 32
Kbytes memory space: four times the memory space of the
FL1D IDEC SmartRelay Memory cartridge.
IDEC SmartRelay allows you to store only one circuit
pr
ogram
in its memory. If you want to modify the circuit
program or create an additional one without deleting the first,
you must archive it somewhere.
You can copy the IDEC SmartRelay ci
rcuit prog
ram to an
IDEC SmartRelay Memory cartridge or IDEC SmartRelay
Memory/Battery cartridge. You can then insert this cartridge
in another IDEC SmartRelay in order to copy the circuit
program. This enables you to manage your programs in the
following ways:
• Archive circuit programs
• Reproduce circuit programs
Warning
Risk of death, personal injury or property damage can occur if you
use the battery cartridge or combined memory/battery cartridge in
a hazardous location.
Use the battery cartridge or combined memory/battery cartridge
only in non-hazardous locations.
