Schneider Electric 140DDI85300 Discrete Input Module

The Schneider Electric 140DDI85300 Discrete Input Module is a 32-channel digital input module for the Modicon Quantum platform, designed to accept 10–60 V DC signals with sink-type (positive) inputs. It provides 32 green LEDs for input status and a single bus-communication LED, with a backplane bus current requirement of 300 mA and 700 Vrms DC isolation between group and bus. The input voltage is specified as 10–60 V DC, with guaranteed high/low voltage states depending on the input range (for 12 V, high 9–12 V; for 24 V, 11–24 V; for 48 V, 34–48 V; for 60 V, 45–60 V), and an absolute maximum of 75 V. Addressing requires two input words, and the module is organized into four groups of input channels and requires two input words for addressing.
