Product Description

The 1769-ECLK Module, part of the Allen-Bradley ECLK series, is a dedicated real-time clock expansion module designed for integration with the 1769-CompactLogix control system. It provides precise timekeeping and event timestamping capabilities, operating within a 24V DC voltage range and an ambient temperature range of 0°C to 60°C. The module connects directly to the controller via the backplane, occupying one slot in the 1769 chassis, and supports seamless synchronization with other CompactLogix I/O modules. While it lacks traditional digital or analog I/O channels, the 1769-ECLK excels in applications requiring accurate event logging, such as manufacturing, energy management, and process automation. Key advantages include battery-backed memory for data retention during power loss (typical battery life: 5 years) and millisecond-level timekeeping accuracy. Its primary limitation is dependency on the host controller for configuration and operation. The module is widely used in industries demanding regulatory-compliant audit trails and time-sensitive process coordination.
