 Input Derating

Using LT input voltage that exceeds the rated voltage, the input ON voltage, the number of input points or the

LT’s temperature can effect. Also, the LT’s input section could overheat, which could lead to an accident or

malfunction. Refer to the following drawing and perform Input Derating within the LT unit’s rated range.

*1 In the case of IN0, IN2, IN4, and IN6, the input delay time generates a 5µs-

delay. For example, in the case of a 0.5ms-cycle sampling:

5µs (ON to OFF) + 0.5ms (sampling cycle) + 5µs (OFF to ON) = 0.51ms

A minimum 0.51ms-restriction is imposed on the input pulse width.

In the case of IN1, IN3, IN5, and from IN7 to IN15, the input delay time gen-

erates a 0.5ms-delay. For example, in the case of a 0.5ms-cycle sampling:

0.5ms (ON to OFF) + 0.5ms (sampling cycle) + 0.5ms (OFF to ON) = 1.5ms

A minimum 1.5ms-restriction is imposed on the input-pulse width.

*2 Digital filter can be set at intervals of 0.5 ms.
