ViewMarq Industrial-Grade LED Message Displays

The ViewMarq line of industrial-grade LED message displays utilizes the latest LED and communications technologies to help communicate important information in industrial environments.

Used to display preformatted messages or factory floor data, the displays can be controlled from a PLC or any device that uses supported protocols. Embedded data support allows real-time production data from the controller to be contained within messages.

ViewMarq Industrial-Grade LED Message Displays

ViewMarq LED message displays support embedded string and numeric variables, as well as blinking text and scrolling (left, right, up, down) messages. They feature tri-color LEDs (red, green, amber) and are available in six models: 1 line x 12 character, 2 lines x 12 character, 4 lines x 12 character, 1 line x 24 character, 2 lines x 24 character, and 4 lines x 24 character.

The rugged industrial design features heavy-duty extruded aluminum housings with durable polycarbonate end caps and a smoked polycarbonate lens cover. Access covers with seal-tight cable glands offer reliable, easy installation of power and communication wiring. The displays are NEMA 4 and NEMA 12 (indoor only) rated and will withstand washdown conditions.

Displays have 140° viewing angles, can be mounted in any horizontal position (wall, ceiling, cabinet), and can be wired for 100-240 VAC or 24 VDC power. Each unit is equipped with an accelerometer to ensure your message is automatically displayed in the upright position.

All ViewMarq message displays are fitted with (1) RS-232, (1) RS-485, and (1) Ethernet port, and can be connected to a PLC, PC, or any device capable of serial ASCII master, Modbus RTU, or Modbus TCP communications.

Programming the ViewMarq industrial-grade LED message displays is easy. The ViewMarq Configuration Software can be downloaded at no charge from the AutomationDirect site (a CD version is available for $10). The software utility provides multiple functionality; users can create and preview messages in the simulator window on a PC, send the message to the ViewMarq LED display, configure the display to communicate with a PLC, and create ASCII string commands to be used in the PLC program.

ViewMarq prices start at $499 and include chain mount and adjustable wall mount bracket assemblies, cable glands for input wiring and a seven-foot Ethernet patch cable. Backed with a one-year warranty, all displays are UL 508 listed, CE, RoHS, and REACH compliant.
