1、 Features of Small Screen Color Paperless Recorder
1. Diversified display functions
Various element screens such as overview screen, bar chart screen, real-time trend curve screen, historical curve recall screen, list query screen, etc. are used to display instrument information. They have a large amount of information, high resolution, clear screen, user-friendly interface, and a wider range of numerical values for displaying engineering quantity data. They can display 4-digit values: -999~9999
2. Universal channel input
Fully isolated universal input, capable of simultaneously inputting multiple signals without the need to replace modules, can be configured through software, and has strong versatility.
3. Fully functional settings
Multiple parameters (including system configuration parameters, input/output channel parameters, communication printing parameters, etc.) can be configured and set for easy operation. There is also a copy and paste function on the clipboard for users to easily set parameters.
4. Rich optional/additional features
Optional functions: data backup, serial communication, serial printing, alarm function, power supply output, transmission output, etc.
Additional functions: flow accumulation, quantitative control, batch control, relay delay, etc.
(Optional functions need to be specified by the customer when ordering, additional functions need to be customized)
5. Strong applicability and reliability
The daily maintenance workload is very small, the operating cost is low, the application field is wide, the anti-interference performance is good, the stability is high, the response speed is fast, and the compatibility of data transfer is strong.
