This document is the user manual for the digital input/output modules of ATCS Haiwei Shen Technology (Shenzhen) Co., Ltd. It introduces the parameters, functions, and installation and connection methods of the 16-point and 32-point DC/AC input modules and the DC output module.
This manual provides detailed information on ATCS digital input/output modules, including the 16‑point DC input (IDD40), 32‑point DC input (IDD50), AC input modules (IDA40, IDA41), and various output modules (ODD40, ODD42, ODA40). Each section describes electrical parameters, front‑panel indicators, and wiring connections.
Installation, wiring, and environmental specifications are also included, helping users correctly mount the modules, connect external terminals, and understand operating limits such as voltage ranges and temperature conditions. This manual is written in Chinese.
