4D Systems 4Discovery-50 HMI for Home & Building Automation

4D Systems 4Discovery-50 HMI for Home and Building Automation belongs to the 4Discovery family which is a suite of intelligent wall-mounted display solutions that assists engineers, and developers. This 4Discovery family of display solutions drives the capability to develop display solutions for building automation systems that put human choices at the center, right at their fingertips. The 50-HMI display solutions are designed to be mounted directly onto a panel, wall, and flat drillable surface. These 50-HMI displays feature a DIABLO16 processor that is programmed by Workshop 4 IDE software to provide stand-alone functionality. The 4Discovery-50 HMI displays feature a high-resolution 480x854 pixel display, capacitive touch, micro-SD memory storage, a two-wire RS485 interface, a proximity sensor, and a switch-mode power supply. The 4Discovery-50 HMI also offers a daughterboard that can be modified to meet specific requirements. The 4Discovery-50 HMI is available in 76.2mm x 139.4mm x 24.8mm dimensions that come with RoHS and CE compliant.

The 4DISCOVERY-50 is available in Daughter Board 1 (DB01) configuration and the 4DISCOVERY-50W features DB01 with WiFi and Bluetooth enabled. These displays are used in applications such as elevator control systems, lighting control, controlling blinds, HVAC control, security and access control, and general machine control.

5 Key Benefits of 4Discovery

Open Protocols - The 4Discovery family is an open protocol, as opposed to using patented closed protocols, allowing easy collaboration in building automation.

Power Over Ethernet Devices Connectivity - Built into the 4Discovery family is the capability to connect to POE-enabled drivers via RS485 serial cable, saving costs by enabling power and ethernet access through single connectivity.

Quick Prototype Testing - With the 4Discovery family, there is no need to wait long to get feedback due to the unrivaled ability to provide quick prototype testing of ideas.

Creative Aesthetics - The 4Discovery family exhibits a stylish product range that can be customized to meet the architectural needs of the environment it is used in.

Exceptional Cost Control - The 4D SYSTEMS hallmark for cost-effectiveness is its modular design offerings for all of its solutions, eliminating start-up costs that severely affect cash flow and can hinder innovation.
