Product Name: Multi-Range High Precision J/K/T/E/R/S/B Types Thermocouple Signal Isolator Data Acquisition Module Device Model NO.: SY AD08T Input: Thermocouple Signal Output: RS232/RS485 Communication Port: RS232 or RS485 Channels: 8-Channel Package: DIN-Rail Weight: about 120g Dimension: 101 Mm X 23 Mm X 116.5 Mm Operation Temperature: 45 ~ +85 Centigrade Endure Impact Voltage: 3kvac, 1.2/50us(Peak Value) Export Market: Global Trademark: SUNYUANSZ Transport Package: DIN Rail Mounting Type Specification: CE, ISO9001: 2008 Origin: Shenzhen Product Description Multi-Range High Precision Thermocouple Signal Data Acquisition Module8-Channels Thermocouple Signal to RS232/RS485 A-D ConverterSY AD08T Series Thermalcouples Signal A-D ConverterRemarks:The model selection of SYAD08T series is just initial type of thermocouple which supports by the module. User can change the types of thermocouple by re-configurating the module through ASCII character command, then calibrate it.SYAD08T series modules support both RS232 and RS485 communication interface. User can choose the communication interface according to the application environment, and at the same time only one interface works,otherwise it may interference with each other.ThemalcoupleA-D ConverterTechnical Parameter:(typical @ +25ºC,Vs is rated value)Input: Thermocouple: J type: 0ºC~760ºC,K type: 0ºC~1000ºC,T type:-100ºC~400ºC, E type:0ºC~1000ºC,R type: 500ºC~1750ºC,S type:500ºC~1750ºC,B type: 500ºC~1800ºC (Input type can be set through software)Accuracy: @+25ºC as shown in Table 1.Input Imbalance: ±0.02 uV/ºCTemperature Drift: ±1 ppm/ºC(±3 ppm/ºC, Max.)Input Resistance: 100 M ΩBand width: thermocouple -3 dB 3.27 HzSwitching rate: thermocouple 3.76 SpsCommon mode restraint (CMR): 120 dB(1kΩ Source Imbalance @ 50/60 Hz)Normal mode restraint (NMR): 60 dB (1kΩ Source Imbalance @ 50/60 Hz)Input terminal protection: 240Vrms, sustainable ANSI/IEEE C37.90.1-1989 transient protectionCold Junction Compensation SensorAccuracy: @+25ºC ±0.25ºC (±0.75ºC, Max.)Accuracy: +5ºC~+45ºC ±0.5ºC (Non-linearity ±0.0125ºC/ºC)Communication: RS-485 interface or RS-232 interface;ASCII character protocol and MODBUS RTU communication protocol.
