MITSUBISHI
MELSEC-L series DC input unit.
[Features]
· A wider range of lineup than the common type in voltage and number of input points.
· No need to use different units as positive/negative commons are shared in all models of the DC input unit.
· The response speed can be selected based on the connecting target.
[Applications]
· For receiving external ON/OFF signals and transmitting ON/OFF signals externally.

Shared Use for Positive Common / Negative Common
All DC input unit models share a positive common and a negative common, eliminating the need to use separate units.
Selectable Response Speed According to Equipment to be Connected
All DC input units are capable of selecting the response time from 1 ms, 5 ms, 10 ms, 20 ms and 70 ms, according to the equipment to which it is connected.
