1.Summary
Main characteristics
The interface is fully protected, accidentally touching the 24V, and even 220V communication, will not be damaged.
Communication, collection, power supply, the three part is completely isolated.
Be based onRS485Interface,ModbusProtocol temperature acquisition module.
quarantineRS485Interface supportModbus-RTUAgreement.
SupportPT100Temperature sensor two wire, three wire connection, four wire connection.
The temperature calculation is completed inside the module, and the temperature value can be read directly. The unit is centigrade.
Measuring range:200+ 650, resolution 0.001,The accuracy can reach 0.1 between -20 and +150. The accuracy of other temperature range is better than 0.25.
Power source: DC 8-30V.
Use standard 35mm Installation way of guide rail.
Outline size:88*72*59
Operating temperature:-35+50.
Applications: liquid and gas temperature measurements.
