MITSUBISHI

Caution

Product Description

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.
