【英文介绍】
The DP840 is an I/O module that is mainly used as a local extension to the AC500CPU.
The module has multiple channels, each of which can be used for pulse counting or frequency speed measurement, and supports a maximum of 20kHz. In addition, each channel has a configurable
input filter, and the module also has periodic self-diagnostics and advanced diagnostics for single or redundant applications.
The DP840 module is particularly suitable for NAMUR interfaces and supports 12V and 24V sensor signal levels. It can also read the input as a digital input signal and add up the pulse count in a
16-bit counter. This makes DP840 have a wide application prospect in industrial automation control system.
The DP840 module also has the ability to communicate with other devices and systems. It has two integrated serial ports, each of which can be set to RS232/RS485, which enables the module to
exchange data and communicate with other devices. In addition, the DP840 module is equipped with a display screen and 8 function keys for easy diagnosis and status display.
In terms of scalability, the DP840 module supports CPU central scaling up to 10 local input/output expansion modules. At the same time, in addition to the integrated communication port, each
CPU can expand up to 4 different communication processors to run simultaneously in any combination. This powerful scalability enables the DP840 module to meet a wide range of complex
industrial automation needs.
Overall, the DP840 is a powerful and stable I/O module suitable for a wide range of industrial automation control systems. Its multi-channel design, advanced diagnostic function and powerful
scalability make it widely used in the field of industrial automation.
