The 750-410 is a 2-channel digital input module that receives control signals from field devices like sensors. It features two high-side switching inputs that operate with a 24 VDC signal voltage, accepting a voltage range of 15 to 30 VDC for a '1' signal. Each input is equipped with a 3 ms digital filter for noise rejection, and the module provides 500V isolation between the system and field levels. It supports connections for 2-wire, 3-wire, and 4-wire sensors. This module is ideal for industrial automation applications requiring reliable digital signal acquisition, with green LEDs indicating the status of each input channel.
