JCCK Smart Temperature & Humidity Transmitter
The JCCk explosion-proof series temperature and humidity Sensor can be customized and output a wide range of signals. It can also take four control outputs for automatic control of heaters, refrigeration air conditioners, humidifiers, and dehumidifiers. This product uses a combination of recursive averaging digital software filtering, and hardware circuit filtering. It minimizes external interference to the sampling as much as possible. As a result, it has high full-scale accuracy, stable performance, consistency, and fast response time. In addition, it can have a built-in buzzer alarm. All control states are indicated by graphic icons and Chinese characters on the LCD board.
JCCK Temperature & Humidity Transmitter
- LED display, acute setting to modify the range, no need to recalibrate.
- Output RS485 signal or 4-20mA, high precision and maintenance-free.
- Save wire and installation meter costs.
- With three keys for more convenient operation, data processed by a single-chip computer high stability.
- With anti-reverse connection, anti-surge, anti-vibration, moisture-proof, heat-proof, and anti-harmful gas functions.
- A wide range of applications can be used in chemical, metallurgical, petroleum, electric power, environmental protection, water treatment, pharmaceutical, food, and other automation industries.
JCCK Temperature & Humidity Transmitter
The JCCK series RS-485 communication line uses a shielded twisted pair cable. One end is connected to the serial communication port of the computer through the RS-232/485 conversion module, and the other is connected to the communication terminal of the RS-485 module.
The shield of a two-core shielded cable should preferably be connected to the protective ground of the device at one end. When a computer is connected to more than one instrument, the network topology is bus type, and each device must be connected directly to the trunk line in parallel. To reduce signal reflection interference. When the communication distance is long, a relay module is available.

Black wire: GND working power supply – (connected to PC serial port pin 5 for 232 communication, every day “-” end of signal for analog signal output)
⑤ Other types of connection
Please check the wire itself for the “wiring label.”
Note: Please ensure the wiring is correct before powering up the unit for measurement. Transmitter signal output is strictly prohibited due to the wrong connection with the power supply, leading to burned integrated chip!
The JCJ series RS-485 communication line uses shielded twisted pair cable. One end is connected to the serial communication port of the computer through the RS-232/485 conversion module, and the other end is connected to the communication terminal of the RS-485 module.
The connection is as shown in the diagram.
The shield of a two-core shielded cable should preferably be connected to the protective ground of the device at one end. When a computer is connected to more than one instrument, the network topology is bus type, and each device must be connected directly to the trunk line in parallel. To reduce signal reflection interference. When the communication distance is long, a relay module is available.
