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.

X-600M Setup and Programming Demo

X-600M Setup

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.
