Multi-channel Controller (max. 80 channel) Porstech


Details :
1. 8~80 inputs for option
2. input can be RTD, thermocouple, standard process current, voltage
3. Basic error: 0.2%FS, display range: -1999~9999
4. Input type, measuring range, alarm value is set independently for each channel
5. Zero and full span of each channel can be set (corrected) independently, which minish sensor’s error efficiently, increase measuring accuracy of the system;
6. Digital filter time constant can be set independently for each channel, then the anti-interference strength has been increased efficiently;
7. Easily enable and disable display of the channels
8. Two grades parameters. Parameters of the second grade are protective by password from mis-operate;
9. With parameters copy function to save works for parameters setting.
10. Standard four alarm output;◆ SPECIFICATIONS:
