*1 Indicates hour rate per day (24hr) at programmable controller power ON.
(Total hour at power ON: 12hr, total hour at power OFF: 12hr become 50% each for current-
carrying hour rate)
*2 Indicates the total power failure time we guarantee , whose range is within -25 to 75
storage ambient temperature (0 to 55
memory (SRAM) characteristic value provided by the parts manufacturer.
*3 Indicates the total power failure time within 40
which is calculated base on our actual measurement value.An actual value varies according
to parts characteristics. Take some sorts of reference to these values.
