#1 This value can change due to the switching frequency, environmental conditions, 

and desired reliability level, therefore it is recommended to check this with the 
actual load. (AgPd contact type or SX relays are available for low level load 
switching [10V DC, 10mA max. level])

#2 The upper limit for the ambient temperature is the maximum temperature that 

can satisfy the coil temperature rise. Under the packing condition, allowable 
temperature range is from –40 to +70°C 

–40° to +158°F
