English Specification Manual (Full Text, No Images)


1. General Description

140DAI75300 is a 1‑slot standard AC discrete input module (diagnostic, non‑fused) for Schneider Electric Modicon Quantum PLC. It provides 32 channels of 230 V AC digital input, arranged in 4 electrically isolated groups (8 channels per group). Designed for general‑purpose 230 V AC input applications requiring group isolation and fault diagnostics, without on‑board fuse protection.
