Condition:New
Type:Logic ICs
First, product introduction
The transmitter has built-in multiple protection against lightning, anti-reverse, over-current, etc. The product is fully interchangeable and is used to accurately measure the concentration of flammable gas. The transmitter acts as a slave to transmit the air pressure through the industrial universal interface RS485. The software was developed in full compliance with the standard MODBUS RTU serial communication protocol. It can be well compatible with WINCC, Kingview, Force Control, Kunlun Tongzhou, touch screen, PLC and other PC configuration software and hardware, as well as software or hardware developed by third parties according to the standard MODBUS RTU protocol. And optional LCD screen display measurement data, after the limit of the buzzer sound alarm prompt, after the limit of the alarm relay drive alarm device action and other functions. This transmitter can supply and communicate with only one 4-core communication cable to transmit sensor data remotely. It can save a lot of cables on the construction site, and the price advantage is very obvious.

Maximum power consumption: 100mA@12V with LCD (0802)
Display mode: LED indicator or LCD screen
LCD screen specifications: LCD0802 8 characters * 2 lines
Communication interface: RS485
Communication protocol: MODBUS RTU
Communication rate: Software settings, 2400, 4800, 9600, 19200, 38400, 115200, etc. Default 9600bps
Data format: default 8N1 (1 bit start bit, 8 data bits, 1 stop bit, no parity)
Communication mode: The transmitter acts as a MODBUS RTU slave station, and the master station (touch screen, PLC, host computer, etc.) uses the master-slave polling method to query the real-time data of the transmitter.
Node address: 1~255, DIP switch or software setting
Number of nodes: theoretically up to 128 transmitters on the same bus, the actual application takes up 1/2~2/3
Transmission distance: 1000 meters (RS485 communication dedicated cable)
The transmitter has been treated three times before leaving the factory to ensure long-term use under high temperature and high humidity special soil.
Installation method: wall-mounted
