Multi-loop digital display controller
The number of inspection channels of the multi-circuit digital display controller can be arbitrarily set. The standard specifications of the XMX series instruments are eight, sixteen and thirty-two; the XMX-LCD has eight and sixteen specifications; the XMX-M has only eight inspection channels.

The meter has multiple types of input functions, each channel can set different input signals (thermocouple / RTD / linear voltage / linear current / linear resistance), greatly reducing the number of tables. It can be used with various types of sensors and transmitters to realize measurement, display, alarm control, data acquisition and recording of physical quantities such as force, temperature, capacity and pressure level. There are two independent alarm set points in each channel. The alarm mode (upper and lower limit, lower limit, upper limit or lower limit) can be set arbitrarily through the parameters, and output through two common alarm relays.
The XMX-M meter can also output two alarm points per channel as independent alarm relays. The instrument can be equipped with a communication component (RS232/RS485), communicate with the host computer, or connect to the micro printer via the RS232 interface to print/measure the measurement data of each channel regularly.
The XMX-LCD meter features a 128*64 LCD display with 8 channels of data per screen.
Second, the functional characteristics
|signal input||16 loop universal input. Using digital correction and self-calibration technology, the measurement is accurate and stable, eliminating the error caused by temperature drift and time drift.|
|Resolution setting||Each loop can independently set the display range and the decimal point position, and perform zero point correction. When the input is thermocouple/thermal resistance, the display resolution (decimal point position) can be selected.|

The upper and lower limit alarm values of each circuit are independently set, and the upper and lower limit alarm modes are set freely. The instrument is equipped with two public alarm relay outputs; when the meter is input for 8 measurement signals,
Optional 8-point upper and lower limit alarm relay output
|Hand/automatic inspection||Manual check and automatic patrol switching function, automatic patrol switching time can be set (in seconds).|
|Power supply||Super-strong switching power supply, stable operation between 100~240VAC.|
Third, technical parameters
|Input specification||The instrument is divided into eight loops and sixteen loops.|
|Precision||Display range: -1999~9999|
|Measurement accuracy: ±0.3%F·S, automatic compensation for temperature drift and time drift|
|output method||Alarm Output:||The normally open contact capacity is 2A/220VAC or 2A/24VDC, resistive load;|
|Normally closed contact capacity is 2A/220VAC or 2A/24VDC, resistive load;|
When the relay contact is connected to an inductive load, the spark absorption circuit must be connected at both ends of the load.
And the load capacity is reduced accordingly.
|communication method:||RS232C, RS485, baud rate 1200~19200bps|
|Print interface:||RS232C direct connection to micro printer|
|Parameter storage||The number of meter parameters set by the panel (or communication write) is 1 million times, and the parameter setting value can be saved for 100 years.|
|power supply||Switching power supply: 24VDC/VAC±10%, power consumption ≤4W; switching power supply: 100~240VAC, power consumption ≤4W|

※ When the instrument communication output position selects R or P module, the instrument has the printing function, but the R module meter needs to reset the internal clock of the instrument after power-on. When the P module is selected, it is not required.
