The 750-1405 is a 16-channel Digital Input Module at a width of just 12mm. It receives binary control signals from digital field devices (e.g., sensors, encoders, switches or proximity switches). Cage Clamp? terminations provide direct insertion of solid conductors. Each input channel has a noise-rejection RC filter with a 3ms time constant. A green LED indicates the switched status of each channel. An optocoupler provides electrical isolation between the bus and the field side.
