Our latest custom order, the DC-405T-DN-W-NEG, is a purpose-built 4-inch high digital timer specifically designed for environments where clear visibility, versatile control, and status signaling are essential. This five-digit timer includes a unique fifth digit that displays a minus sign when the countdown transitions through zero and begins counting back upward, providing intuitive tracking of both countdown and elapsed overtime.

What makes this configuration especially unique is the integration of multiple control and alerting systems tailored to the customer’s needs. Here’s an overview of the key features and functions:

Key Highlights of the DC-405T-DN-W-NEG:

• 4-Inch High, Five-Digit Display
  Designed for visibility in industrial or commercial environments. The fifth digit automatically switches to a minus sign when the timer crosses zero and begins to count back up.

  • Work in tandem with the End of Period alert system for added visibility.
• Redundant Control Systems
  This display includes:
  • Wireless Controls (2.4 GHz)
