H04DT without RS485 interface can only be hung behind the host PLC for using; H32DT with RS485 interface not only can be hung behind the host PLC as the extend module, but also can be used as a remote
Wiring as shown below:Note:1.VDD (Vdd+) and GND (Vdd-) as the power supply terminal of sensor, it can be connected to the nearest.2.The cable between DS18b20 sensor and modules is recommended to be th
POW indicator: Power indicator, green. Always on---Normal power ; Not on---Abnormal power.AI indicator: Analog input indicator, red. Always on---sensor is connected correctly, Not on----Sensor is not
H04DT can connect with not only digital temperature sensor DS18B20, but also the sensor SHT1x (SHT7x), the temperature measurement range of DS18B20 is -55 ~ + 125 ℃; The sensor SHT1x (SHT7x) can measu
1. H04DT and H32DT have the same shell size and the appearance is delicate.2. H04DT has four channels of temperature and humidity input,it can be used to accurately measure temperature and humidity wi
Yes, it has photoelectric isolation. Non-isolation between analog channels, between analog and digital there is photoelectric isolation.
The A+B- terminal of S04XA is a RS485 communication port. When S04XA is hung behind the host PLC as an extend module, the two terminals do not need any wiring; When the S04XA is used as a remote modul
The two terminals of analog output can not be connected in parallel. If you want to make a backup, you need to add a toggle switch between the two channels of analog. Use the toggle switch to control
