Digital display instrument
Fully isolated temperature inspection instrument

● Scope of application

DX-500G full-isolated temperature inspection instrument is used in conjunction with various sensors and transmitters. The fully-isolated temperature inspection instrument can perform roving detection on multiple process parameters such as temperature, pressure, liquid level, flow rate, and weight. Alarm control, transmission output, data acquisition and communication.

● Features

Universal input function Automatic calibration and manual calibration function Multiple protection, isolation design, strong anti-interference ability, high reliability
Good software platform for fully isolated temperature inspection instrument , with secondary development capability to meet special functions
Fully isolated temperature inspection instrument with advanced modular structure, combined with powerful instrument chip, function combination and system upgrade are very convenient. Automatic inspection inspection, manual inspection inspection can be freely switched. Inspection channel switching time and effective number of channels can be set.

● Main technical indicators

Basic error: 0.2% FS ± 1 word Resolution: 1/20000, 14-bit A / D converter Display mode: Double-row four-digit LED digital tube, upper row shows measured value, lower row shows channel number Sampling cycle: 0.5 S
Alarm output: ⑴ 1-64 channel unified upper and lower limit alarm, relay output contact capacity AC220V / 3A
⑵ Independent alarms for channels 1-8, relay output contact capacity AC220V / 1A
Transmission output: The corresponding channel can be selected through switch input with 4 ~ 20mA, 0 ~ 10mA, 1 ~ 5V, 0 ~ 5V isolation output accuracy: ± 0.3% FS
Communication output: interface mode-isolated serial two-way communication interface RS485 / RS422 / RS232 / Modem
Baud rate: 300 ~ 9600bps internal freely set power: switching power supply 85 ~ 265VAC power consumption below 4W
