The T80 controller utilizes advanced micro-processing technology for intelligent control. It is designed to handle various physical quantities such as temperature, humidity, pressure, liquid level, instantaneous flow rate, speed, and the display and control of detection signals. The controller is capable of accurately measuring non-linear input signals through high-precision linear correction.
● Supports the input of hot couple, thermal resistance, voltage, current and two-wire transmitter;
● Have single channel and universal signal input functions. Easy to switch signals;
● High brightness LED digital display and high resolution light column display scale display;
● Input and output circuits are optoelectronic isolation with strong anti-interference;
● Supports 4 alarm functions, independently including 2 upper/lower limit alarms.
● Constant water pressure supply;
● Industrial automation;
● Thermoelectric chemical industry, steel and coal.
● XDB905 water level indicator digital designed for water pressure supply and industrial automation.
| Parameter | Name | Description | Setting range | Factory default |
| AH | Upper limit alarm | When the measured value PV>AH value,the meter will cancel the upper limit alarm. | – 1999~9999 | 300 |
| H | Upper limit alarm hysteresis | aka dead zone,stagnation.The hysteresis is used to avoid frequent misoperations
of the bit adjustment output due to the fluctuation of the measured input value. |
0~9999 | 0 |
| AL | Lower limit alarm value | When the measured value PV<AL value, the lower limit alarm will be generated,
and when the measured value PVXAL+dL) value, the instrument will cancel the lower limit alarm. |
– 1999~9999 | 200 |
| L | Lower limit Alarm | Same as(dH) | 0~9999 | 0 |
