For any questions or concerns our sales department.

The X-332™ is a robust, full-featured, web-enabled Ethernet I/O module. It has 16 independent relays, 16 optically-isolated digital inputs, 2 counter inputs, 4 analog inputs, support for up to four temperature sensors, and the ability to control relays remotely on other ControlByWeb devices. It also has many additional features such as a full calendar scheduler, a BASIC script interpreter, logging, and a real-time clock with NTP synchronization.

The X-332 has a built-in web server so its relays and inputs can be controlled and monitored using a standard web browser (or by using our CBW Mobile smartphone app).

Additionally, temperature data can be graphed directly from any HTML5 compatible web browser. Email alerts can be configured based on relay and/or input states, and temperature thresholds.

Some of its many advanced features include the ability to initiate a connection to remote servers, BASIC programming, SNMP, peer-to-peer communications, internal monitoring, etc.

Simply access and configure the X-332 by using its web-based user interface. There is no software required, no subscription to buy, and no programming necessary for setup or use.

The X-332™ is designed for accuracy and reliability, and is an innovative solution for a number of applications.


The X-332 is a simple but powerful Ethernet I/O (or web I/O) device that can be used for thousands of applications from event counters, to machine monitoring/control, building or equipment automation, to extending I/O from a PLC to another building and much more.
