YL-C803 Intelligent Display details alarm control instrument: intelligent display Alarm; intelligent alarm controller Product details YL-C803 series intelligent instrument design core idea is universal, that is universal indexing number to fit a variety of signal input / new generation of intelligent universal digital output (beam) display controller. It thermocouple, RTD, transmitters, sensors and other instruments with, can be used in metallurgy, electric power, petroleum, chemicals, machinery manufacturing, heat treatment, light industry and other industries. Meter set by the user by setting the key parameters to achieve the proper pressure, temperature, flow, level, speed, voltage, current, frequency and other industrial parameters indication, alarm and output. Anti-interference ability of the instrument may be suitable for large power fluctuations occasion use, power supply range 100 ~ 260VAC / DC or 24VDC Features ◆ instrument simple, versatile, a multi-purpose table. The user through the keyboard settings, can achieve a variety of input signal types, greatly reducing the number and cost of standby instruments. ◆ Software zero full-scale adjustment to eliminate temperature drift and time drift caused by measurement errors, display accuracy of better than 0.2% FS. ◆ instrument uses digital filtering technology to identify, suppress low frequency disturbances and irregular sources of interference conditions associated measurement signal system, thereby improving the noise immunity. ◆ freely selectable output: relay contact, SSR drive level, SCR zero and phase pulse contact output; analog transmit output; 24VDC power feed output. ◆ with automatic monitoring software failure, the alarm function. ◆ new patch welding technology, the instrument nice, strong anti-interference. ◆ using snap-on design, easy installation, maintenance, replacement; installation dimensions and domestic and foreign common instrument.
