BTENS-ZFD210 - Digital module for load cells

BTENS-ZFD210 digital weighing transmitter is designed for all kinds of industrial applications. It is using Delta-sigma analog-to-digital conversion and digital filtering processing technology. Digital processing through the weak weight signal output by the symmetric heavy sensor (group) is output to the user’s upper position system via the RS485 serial port communication. It allows to easy form a weighing system with the touch screen or PLC. The transmitter has the characteristics of high accuracy, high interference resistance, high linearity, performance stability, simple operation and support for various protocols.

POWER SUPPLY COMMUNICATION

The power supply range of the transmitter is DC: 6V-12V

+	-
Positive power supply	Negative power supply

SERIAL COMMUNICATION

BTENS-ZFD210 provides RS485 serial ports for communication with the upper computer. There are three protocols: ASCII, Modbus, and Freedom. The default is the Modbus protocol, which can be modified into two others by sending instructions.

Note:
In the case of larger load cell, the digital module can be hidden inside the structure of load cells .
