X-401 Overview

The X-401 is an easy to operate and very capable Ethernet I/O PLC that’s a great fit for large and small IIoT applications. It can monitor up to 2 contacts and control up to 2 relays. Configure and access your device through a standard web browser—no special software required.

X-401 Features

  • Email Notifications
  • No-Code Logic Builder
  • Peer-to-Peer Communication
  • Data Logging
  • WiFi Connectivity (X-401W Only)

X-401 Applications

  • Door & Access Control
  • Network Device Rebooting
  • Alarm Panel Monitoring
  • Motor Control

When a hardwired Ethernet connection isn’t practical, WiFi connectivity allows you to easily monitor and control your I/O module wirelessly. The built-in WiFi capability of the X-401W allows you to create logic, monitor inputs, and trigger relays through a standard web browser and WiFi network. (Note that an Ethernet connection is required for initial setup of 400 Series devices.)

The Benefits of WiFi PLCs

  • Flexibility: WiFi-enabled PLCs are often used when a hardwired Ethernet connection isn’t feasible.
  • Cost: With WiFi, integrators can avoid the expense of burying a line, channeling Ethernet cables, and installing other physical components.
  • Ease of Installation: Our WiFi-enabled PLCs can be assigned network credentials through the built-in interface.

400 Series Setup and Programming Demo

X-401 Setup

The diagram illustrates how this demonstration is wired. Nothing is connected to the relay contacts; however, you can still turn the relay on and off to see how it works. The input state only changes when a voltage is applied to the input. For this demonstration, we have connected one of our X-332 controllers to the input of the X-401. You can apply a voltage to the input of the X-401 by accessing the control page for the X-332 (Digital Input Control Page).

Important Information

  • Multiple users may be accessing this device simultaneously so the device can change while you are using it.
  • This unit will be reset to factory defaults daily at 2:30AM MST.
  • Please DO NOT change network or password settings.
