hart to 485, hart to 4-20mA, modbus protocol, SM100-G

An ARM CPU, a HART protocol modem chip, and a great deal of real-world experience went into creating the SM100-G HART intelligent alarm controller. It offers great stability and dependability and is designed to meet the specifications of industrial items. The intelligent alarm controller has a standard RS485 interface that allows it to read data in the form of 4–20ma current and transfer it transparently with the intelligent instrument using the HART protocol or convert it into MODBUS_RTU protocol. Simultaneously, real-time data is tracked, and when the alarm limit is reached, the alarm action is promptly triggered.
The HART protocol instrument enables bidirectional data transmission without interfering with the 4 to 20 mA analog signal by superimposing a modulated digital signal on a 4 to 20 mA basis using the Bell202 Frequency Shift Keying (FSK) standard. Digital and analog signals can be modulated and demodulated in both directions using the SM100-G intelligent alarm controller.

    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.
