NDAM-4055 is an 8-channel digital input and output module produced by Guangzhou ZHIYUAN Electronics Co., Ltd. It adopts electrical isolation technology and watchdog technology, supports both switch contact signal and level signal input, and has 8-channel digital opto-isolated output function. It is suitable for industrial field control, remote monitoring and data acquisition, etc.
The NDAM‑4055 module provides eight isolated digital inputs and eight isolated digital outputs, allowing both switch‑contact and voltage‑level signals. It is built with a 32‑bit ARM processor and a real‑time operating system, enabling fast data processing and reliable communication with NDAM network modules.
The module is housed in an industrial‑grade plastic case, mounts on a standard DIN rail, and offers a 3000 V DC isolation rating, ESD protection, and a temperature range of –20 °C to +85 °C. It is suitable for a wide range of industrial applications such as remote monitoring, data acquisition, and control of relay‑type devices. This manual is written in Chinese.
