‹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.

Status Display None
Isolation Method Photocoupler Isolation
External Connection 22-pin connector (used with Output section)
External Power Supply For Signal: DC 24V
*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 IN11, the input delay time generates 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.
