4-20mA to 485 ,analog converter , modbus protocol , SM626H-DA

SM626H-DA data acquisition unit is a micro RTU system, which is based on the advanced ARM-based microcontroller. It is composed of high-precision operational amplifier, interface chip, input and output circuits, and embedded communication module. The RTU terminal for remote data acquisition has the characteristics of stable performance and high cost performance.
The SM626H-DA data collector communicates with equipment with MODBUS-RTU communication function through RS485 interface and supports 4 ~ 20 mA current output.
As SM626H-DA data collector is specially designed for industrial product integration, it adopts special design in temperature range, vibration, electromagnetic compatibility and interface diversity, which ensures stable operation in harsh environment and provides high quality assurance for your equipment.
