1、Can be connected with 4-channel PT100 and 4 K‑type thermocouple temperature measurement inputs 2、Can cooperate with the host to collect the digital value after voltage signal conversion 3、The interface of acquisition module has good contact performance, ensure stable working 4、The initial baud rate is 9600, the station number is 01, the baud rate and station number can be adjusted by instructions 5、Commonly used in industry, equipment monitoring, environmental monitoring and other occasion Item Type: Data Acquisition Module Model: WSM02-1 Material: Engineering Plastic Maximum Working Current(mA): 120 K-type Thermocouple Measuring Range: -60℃-840℃ (+cold junction compensation temperature) Measurement Accuracy: ±1.5℃(±0.2%) excluding cold junction compensation error PT100 Measuring Range: -50℃-450℃ Measurement Accuracy: ±1℃(±0.2%) Wiring Instructions: 1. After the PT100 is connected, the correct temperature information can be read, and the display temperature when the circuit is open is about 265.7℃ 2. PT100 PV, connected to the PT100 single-line end, PS, connected to one of the compensation lines, PG, and connected to the other compensation line (PS and PG are connected to the same color line) 3. The K-type thermocouple is shorted to display the cold junction temperature (equivalent to the temperature difference of the thermocouple is 0), and the temperature rise can be observed when the thermocouple is heated. 1 x Data Acquisition Module
