Knick – 830 X Loop-Powered Process Indicator
Description
Knick – 830 X Loop-Powered Process Indicator
The Model 830 X loop-powered digital indicators are universally applicable. The range (either 0 to 20 mA or 4 to 20 mA) is simply selected via terminals. Display starts working at an operating current of only 0.3 mA. The low voltage drop of 0.5 V allows application in current loops with low load voltage.
Facts:
- Digital indication without power supplies and supply leads
- No signal interference due to power supply coupling
- Power failure without effect on indication
- No parasitic voltages
- Unproblematic, extremely low-cost application in hazardous area
- Universal range selection
- Exchangeable unit symbols
