YD240 Speed Transmitter
A. Overview:
1. YD240 speed transmitter can be used with many  output instruments of our company and also can  be connected to magnetic-electric and other speed transducers.
2. The transmitter uses the unique precision measurement method to ensure the high precision of the whole measuring range.
3. It can distinguish the vibration signal from the larger rotor vibration signal effectively.
4. Set 1-1000 pulses each turn freely. Level 2 alarm control the relay output, the alarm control mode can be flexible setting, all parameters can be set by RS485 communication.
5. Measured value convert to 4~20mA analog output.
6. Imported integrated circuits, filter components strictly; 100% the whole aging and testing to ensure high reliability of the transducer.
7. There is communication interface to connect with the computer.
8. The shell of transmitter is made of aluminum. In order to shield interference from outside, the shell has been connected with the signal ground in the transmitter. Both the mounting plate and the guide rail cassette are engineering insulation plastics, so it can isolate the transmitter and the earth when install the transmitter.
9. Boundary dimension: 78mm(W)×61mm(L)×65mm(H)(base plate mounted, it is compatible with YD9800 of our company and 3300XL of BN company); 90mm(W)×35mm(L)×70mm(H)(guide rail mounted, it is compatible with 3300XL of BN company). Installation dimension: base plate installation 51mm×51mm, use four M4×12 GB29-76 bolt to install; guide rail installation, can be easily installed on standard 35mm guide rail.

Transmitter output

Transmitter will converted  the rotate value to a current signal of 4~20mA or 0~5V voltage 

Upper and lower limits of the transmitter range 

Transmitter output current 4~20mA and transmitter range lower limits and upper limits are linear relationship, when the rotate speed value is less than the lower limits or greater than the upper limits, the output 4mA  and output 20mA unchanged. 




YD240 Speed Transmitter can be connected to the computer or PLC to communicate, comply with RS485 transmission standards. The communication between transmitter with computer is followed the protocol of ModBus-RTU.
