Wireless transceiver

1. A transmitter, with DC0-20mA, DC0-10V acquisition and wireless transmission function, and set a dial switch to control the transmitter / receiver to work / stop;
2. Wireless transmission will use wireless electromagnetic wave 433.4 ~ 473.0MHz, up to 100 communication channels, the maximum distance can reach 1000m, transmission distance is far. But in the effective range of 200m, it can operate reliably, stably and safely for a long time, which is suitable for most of the plant application environment;
3. The signal acquisition terminal at the transmitting end shall have two wire input mode, three wire input mode and four wire input mode, and switch is realized by dial switch;
4. The transmitting terminal has four terminals, which are battery supply terminals 1 and 2, and signal acquisition terminals 3 and 4;
5. The effective straight-line distance between wireless transmitting and receiving device shall be more than 200m, and it shall also be more than 100m if there is metal or wall in the middle. The transmitting and receiving signals are stable within the range;
6. A set of wireless transmitting and receiving devices have adjustable pairing mode, and when multiple sets of pairing are completed, there is no interference and influence on each other (in the same application scenario, the pairing modes can be various, i.e., one-to-one, one to many, many to one, etc.);
7. The circuit board at the transmitting end is powered by 3V or 6V or 9V or 24V dry battery, and has electric energy alarm indicator, that is, when the power is low, there is an alarm indication;
8. The receiving end is provided with an indicator light to indicate whether the signal receiving at the transmitting end is normal.
