SM100-G HART Intelligent Alarm Controller - China Suppliers and Factory for 4-20mA to MODBUS and RS485 Solutions

Introducing the SM100-G HART Intelligent Alarm Controller, a state-of-the-art solution developed with an ARM CPU and HART protocol modem chip, backed by extensive real-world experience. This reliable and stable device meets the rigorous specifications required by industrial applications. Designed for seamless integration, the SM100-G features a standard RS485 interface that allows for the effective reading of data in the form of 4-20mA current. It can transparently communicate with intelligent instruments using the HART protocol or convert data to MODBUS_RTU protocol, As a leading product from China, the SM100-G guarantees real-time data tracking, instantly triggering alarm actions whenever limits are surpassed. The device utilizes the HART protocol for bidirectional data transmission, cleverly superimposing a modulated digital signal onto the 4 to 20 mA analog signal using the Bell202 Frequency Shift Keying (FSK) standard. This ensures that both digital and analog signals can be modulated and demodulated smoothly in both directions, Choose the SM100-G Intelligent Alarm Controller from one of the top suppliers in the industry and enhance your operational efficiency with our innovative technology designed in our advanced factory

Product Details

Product Specifications

Outfitted with a common RS485 communication interface for parity check, communication baud rate, and parameter tuning. It increases the system's overall operating speed because it is not dependent on the HART bus's 1200 communication speed.
Adopt an industrial universal module shell, which makes commissioning and installation easier.
It has specialized configuration software that allows it to set up the SM100-G intelligent alarm controller's parameters and connect to an intelligent instrument that uses the HART protocol. Support for the common RTU and MODBUS protocols.
Capable of customizing the instructions for reading specific HART instruments, it supports a wide range of intelligent instruments with the HART protocol.
The output interface takes the shape of a DO relay with two or four channels.
With an output current of 1/2 4 ~ 20 mA.
The power-off memory function eliminates the need to reset parameters after turning off the power.
The alarm controller's operational state can be plainly seen via the status indicator.
Method of installation: fixed installation or regular rail installation.
