XTMD-100 XTMD-100-D XTMD-100-DB Digital indicator

Overview

XTMD-100 XTMD-100-D XTMD-100-DB Digital indicator is a multi-functional intelligent controller composed of a new generation of special circuits meter. It fully applies contemporary microcomputer technology and new components, adopts SMT Surface Mount Components and Corresponding ProductionThe technology makes the instrument have the characteristics of strong function, reliable performance, small size, etc., and has a high cost performance. The instrument uses four digital tubes and two light-emitting diodes to indicate various parameters and states, which are clear and intuitive. all the fuck。Only three buttons are needed to complete the function, and the operation is extremely simple. The instrument has full input function, and the input signal type can be directly selected on the panel, including common thermocouple, thermal resistance, Radiation temperature sensor, remote pressure gauge resistance input and standard signal input, the latter two signal inputs have Range change function can. The instrument has two relay alarm outputs ___, each of which can be arbitrarily set as upper limit alarm or lower limit alarm, the alarm value Full-scale setting, and alarm insensitive area can be set at the same time, so in addition to being used as alarm output, it can also be used as alarm output. Bit control output。The instrument can be equipped with process variable transmission current output, 0 or 4 can be chosen arbitrarily.

Working priciple 

XTMD-100 XTMD-100-D XTMD-100-DB Digital indicator has normally open to normally closed and normally closed to normally open touch. Take an example to measure the liquid level. After setting the upper and lower liquid levels. When the alarm setting value is exceeded, the buzzer needs to sound, and a rated signal source is provided to the buzzer through the normally open contact. In this way, when the measured value reaches the set alarm value, the contact will change from normally open to normally closed (equivalent to the switch is closed), and the buzzer will sound. The upper limit and lower limit are two pairs of independent contacts, which are actually based on the process requirements. When the upper limit is reached, the corresponding upper limit contact will be connected. It is the same when the lower limit is reached. Connect the corresponding contact according to the action required. (remember, a pair of contacts is equivalent to a switch, and each pair of contacts has a central point, a normally closed point and a normally open point). The intelligent digital display instrument can also set both pairs of contacts as upper limit alarm or lower limit alarm. In fact, the temperature control of intelligent digital display regulator is the same as the liquid level control principle. Set the upper and lower limits of the temperature. When the temperature is higher than the set value, the heating is stopped. When the actual temperature is lower than the set value, the system sends a heating command signal.

Thermal resistance: Caichuan three-wire wiring, the three wiring resistances are required to be equal and less than

3. Resolution: 14 bit

4. Alarm: The instrument has two alarm outputs, which can be arbitrarily set as upper limit alarm or lower limit alarm.

Upper limit alarm action: When the measured value is greater than or equal to (upper limit alarm setting value + alarm insensitive area), the alarm of the instrument will work, the upper limit alarm indicator light will be lit, and the upper limit alarm relay contact will be closed at the same time. When the measured value is less than or equal to (the upper limit alarm setting value - the alarm insensitive area), the alarm of the instrument does not work, when the upper limit - the alarm insensitive area), the alarm of the instrument does not work, the upper limit alarm indicator is off, and the upper limit alarm The relay contacts are open. Lower limit alarm action: - When the alarm is insensitive area), the alarm of the instrument is active, the lower limit alarm indicator light is on, and the lower limit alarm relay contact is closed at the same time. When the measured value is greater than or equal to (lower limit alarm setting value + alarm insensitive area), the alarm of the instrument does not work, the lower limit alarm indicator light is off, and the lower limit alarm relay contact is disconnected. The relay contact capacity is 2A, 250VAC (resistive load)
