2.2 Input Specification
*1 Current leakage from the sensors connected to the inputs might provide enough current
to turn the controller On. Do not use two wire sensors
0
*2 EI1 and EI2 in AL2-4EX can be used as High Speed Counters.
When using the High Speed Counter function, the input response time is 0.5ms or less.
