Core features
Suitable applications
Communication and interfaces
These are the supported hardware interfaces and protocols stated for this product.
Reads switch and sensor states from the control system.
Four outputs for suitable control circuits.
Wireless setup and local connectivity.
Designed for an automation enclosure.
Student view
Study discrete-control logic, where input states and relay actions must be documented and tested carefully.
Example projects showing what this product can read, control and report. Each requires the appropriate sensors, connected equipment and application software.
Example: read status contacts exposed by an existing lift controller through compatible input interfaces. An application can display availability and fault states locally or share them over Wi-Fi with a building dashboard.
Example: receive an approved service-state signal from the lift control system. Use a relay output to operate a suitably rated status indicator or auxiliary notification circuit for maintenance staff.
Example: use a low-voltage model with floor buttons and position switches. Students program request handling and relay-controlled indicators to learn sequencing; this is a teaching model, not a replacement for a certified lift safety controller.
