Introduction
The LC-131 is an easy-to-use digital input module, equipped with 3-channel digital input, functions open/short circuit detection, and 1-channel relay output. The digital input type is dry contact, meaning that wiring is easy. There are two methods of controlling the relay outputs, either directly from the digital input or via a remote host. Settings, such as communication protocol and node address can be configured either via hardware or via software, depending on the situation. The module has also passed ±4 kV ESD reliability test, and is designed to operate in harsh environments.
