Vorne 87-705-4D-3TR Digital Timer Display Module

The Vorne 87-705-4D-3TR Digital Timer Display is a 4-digit, large LED timer designed for elapsed time monitoring and visual process management in industrial production environments. It is commonly installed along manufacturing lines, at assembly stations, downtime monitoring points, and other factory automation applications to provide highly visible process timing and status indication. This genuine Vorne replacement part belongs to the 87/705 Programmable Timer series and offers Mode A and Mode B operation, with time formats that cover seconds, minutes, hours, days, or combinations, and a resolution up to 10 milliseconds for precise timing. The device supports input from PLC outputs, relay contacts, proximity sensors, and photoelectric sensors, and communicates via RS232 as standard with optional RS485 network capability for broader integration. Configuration is flexible through DIP switch settings or the VDP4 programming interface. Its core function is process timing and production monitoring within industrial automation and visual factory systems, making it suitable for assembly systems, manufacturing cells, downtime monitoring, and production efficiency projects that require accurate timing display and clear operational visibility. Common replacements include Vorne 87/705-4D-3TRX, Vorne 87/805 Production Display, and Vorne 87/415 Rate Display Plus.
