Analog 0-10V TORS485 Modbus Converter
-
RM40.00
- Product Code: ZTS-3000-120-485-2-G
- Availability: In Stock
Description:
The module can collect up to two analog signals (4-20mA, 0-10V, 0-5V) on site and convert them to the 485 interface standard ModBus-RTU communication protocol for upload. The maximum communication distance of the 485 interface is 2000 meters, and it can be directly connected to the on-site PLC, industrial control instrument, configuration screen or configuration software. Acquisition accuracy 10-bit (1024) resolution and 12-bit (4096) resolution are optional. It can be widely used in industrial sites, power distribution cabinets and other places where analog signal acquisition is required.
Correspondence of analog
4~20mA: Collect 4~20mA current signal, collect data (10 bit AD): 163~819; Acquisition data (12 bit AD): 655~3276
0~5V: Collect 0~5V voltage signal, collect data (10 bit AD): 0~1024; Acquisition data (12 bit AD): 0~4096
0~10V: Collect 0~10V voltage signal, collect data (10 bit AD): 0~1024; Acquisition data (12 bit AD): 0~4096
Features:
The standard Modbus-RTU protocol is adopted. The address and baud rate can be set by the upper computer software, and can be connected to the 485 bus for use. The products are designed and manufactured according to industrial standards, and have the characteristics of overvoltage protection, overcurrent protection, strong anti-interference ability, and high reliability.

Power input and communication
VCC: Power input positive
GND: power input ground
485A: 485-A
485B: 485-B
Power output and signal input
VCC: Power output positive
GND: Power output ground
IN0: Analog 1 input
IN1: Analog 2 input
The conversion module only needs one end of the power supply to be able to work normally, and the other end of the power supply is prepared for the subsequent stage power supply. If the latter stage is not powered, it can be left floating.
