The X-21S™ expansion module is used with an X-400™ or X-600M™ controller. The four relays are 2.5A Form-C/SPDT contacts. One or more X-21S™ expansion modules can be connected with a ribbon cable that provides both power and communication.
An X-400 or X-600M connected with an expansion module like the X-21S provides 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.
The X-400™ is a web-enabled controller that allows for up to 32 added expansion modules and/or remote I/O devices. Expansion modules are connected directly to the X-400 via ribbon cable, or remotely with other CBW devices via P2P—allowing for monitoring and control of up to 64 I/O.

For your convenience we have set up a live X-600M unit connected to several expansion modules (i.e., X-11S™, X-12S™, X-13S™, X-15S™,and X-16S™). The X-21S™ will be connected and used similarly to these expansion modules. These expansion modules contain a variety of inputs and outputs that allow you to see how the X-600M works with its expansion modules. By clicking the links below you have full access to these live units. You can make changes to the configuration and settings through the setup pages and you can control the expansion modules’ relays, and view the current status of the inputs, and monitor temperature (X-600M & X-13S™) through its dashboard page.
The diagrams illustrate how this demonstration is wired. The relays on all expansion modules are not connected to a load; however, you can still access and control the relays by turning them on or off through the X-600M dashboard. The X-600M is also wired to a temperature sensor, and the X-13S is connected to a thermocouple. Both sensors can be monitored on the X-600M’s dashboard. The digital input states on the X-15S only changes when a voltage is applied to the inputs. For this demonstration, we have connected one of our X-332 controllers to Input 1 on the X-15S. You can apply a voltage to this input 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.
The X-401™ has two SDPT relays (form C) and two optically isolated inputs. It also shares the same benefits as other 400 series devices, which includes a built-in web server and simple, no-code logic builder. Monitor locks and lights, reboot devices like IP cameras, control bells and alarms, and much more with the X-401.
