X-21s™ | Four Relay Form C / SPDT Expansion Module
X-21s expansion module with four relays can be controlled over the internet with an X-400 or X-600M controller.
Overview
The X-21s™ Four Relay Expansion Module is used with an X-400 or X-600M controller. The X-21s has four relays each with Form-C/SPDT contacts.
Required Controller
One or more X-21s expansion modules can be connected to an X-400/X-600M controller with an expansion cable. The expansion cable provides both power and communications to the expansion modules.
Controller Features
The X-400/X-600M are multi-function web-enabled industrial I/O controllers. They perform control, logic, and monitoring functions similar to that of a Programmable Logic Controller (PLC). However, unlike a PLC, these controllers are designed for web-based applications from the ground up.
No add-on software or hardware is required. The controllers can be fully configured, programmed and tested directly in the device using its built-in web server and a standard web browser. The web setup pages are intuitive and easy to use and do not require special programming skills.
Applications
The X-400/X-600M controllers, together with expansion modules, such as the X-21s, provide an easy, flexible, and reliable way to monitor and control systems and devices over a network. The X-21s is suitable for use with moderate loads such as solenoid valves, alarms, and indicator lights.
Other expansion modules with different I/O combinations are also available.
