Product Description

Product overview
 

It can convert the four-channel current signals in industrial field into the digital signals. According to the MODBUS protocol, it can provide digital signals to PHM-7100, PLC or host computer system through RS485 communication. Compared with the traditional PLC+signal isolator mode, it has avoided two conversion errors, so that the conversion accuracy is significantly improved, while the stability and anti-interference of the system are increased.

 

PRODUCT ADVANTAGES

1. Awide range of inputs such as Al,AO, D|, DO, TC,RTD can be provided

2. Compare with traditional PLC+isolated safety barrier, it can avoid the failure through twice signal conversion, increase the transmission accuracy and system stability

3. With DIN rail bus power supply and communication, flexible and convenient

4. High module/channel densities, efficiently save space and cost
