The TA5131-RTC is a real-time clock palette for ABB's AC500-eCo V3 series, which provides accurate real-time clock functionality for PLC systems, ensuring that the system can accurately record time and perform time-related control operations during operation.

Operating voltage: Usually the connected CPU module provides a 5V DC power supply, and its working current consumption is small, generally within tens of milliamps, which will not cause a large burden on the power supply of the CPU.

Operating temperature: standard temperature range of 0°C to +55°C when installed horizontally; The wide temperature range is -20°C to +70°C, and the I/O is derated by 75% at 60°C to 70°C. The standard temperature range is 0°C to +40°C when installed vertically; Wide temperature range from -20°C to +40°C.

Storage temperature: -40°C to +70°C.

Relative humidity: 95% max, non-condensing.

With high time accuracy, the accuracy of the internal clock crystal oscillator is usually about ±5ppm, which can meet the time accuracy requirements of most industrial control occasions, such as timing control, time stamping of data recording and other applications.

Specially designed for the CPU modules of the ABB AC500-eCo V3 series, it has good compatibility and communication capabilities with CPU modules such as the PM5072-T-2ETH (W) of the series, and can be easily installed on the CPU module and interact with data.

The small size and light weight make it easy to install on the CPU module and will not take up too much space and increase the weight burden of the system, but the specific value has not been officially given in detail.
