Overview
The Eaton Durant 53300401 is a compact, battery-powered electronic totalizing counter part of the Courier series. This 8-digit counter module is engineered for simple totalizing applications where reliable pulse counting and add/subtract functionality are required. The unit combines solid-state input technology with an always-readable LCD display, making it suitable for production tracking, flow measurement verification, and piece-counting operations in industrial automation systems.
Key Features
- 8-digit LCD display with lead-zero blanking for clean readouts
- Add/subtract capability using solid-state PNP input sensor signal
- High-speed count input—handles up to 10 kHz solid-state (PNP) pulses
- Separate contact and solid-state input terminals for flexible sensor integration
- Battery-powered operation—no external AC/DC power supply required
- Compact design suitable for panel mounting and integration into existing systems
