Product Introduction
A product called the SM100-M-8 HART data collector was created using an ARM microprocessor, a HART protocol modem chip, and a great deal of real-world experience. It offers great stability and dependability and is designed to meet the specifications of industrial items. To ensure real-time data transmission, the data collector is outfitted with a standard RS485 interface and gateway that can either convert data into MODBUS _ RTU or MODBUS _ TCP protocol to read data or transparently communicate data with intelligent instruments using HART protocol.
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. An clever converter for bidirectional modulation and demodulation of digital and analog signals is the SM100-M series HART data collector.
Frequently Asked Questions (FAQ)
What is the main function of the SM100-M-8 HART data collector?
The SM100-M-8 is designed to connect to HART protocol instruments and convert data into MODBUS_RTU or MODBUS_TCP protocols. This allows standard RS485 and Ethernet interfaces to easily read data or transparently communicate with intelligent field instruments.
How many HART devices can this collector support simultaneously?
It supports the simultaneous connection and parallel scanning of up to 8 HART devices across separate channels.
Does the SM100-M-8 provide power to the connected field instruments?
No, this equipment does not supply power to field instruments. Field instruments must be powered independently.
Will a power failure or fault in the device affect the 4 to 20 mA analog signal?
No, the equipment does not affect the transmission and accuracy of the 4 to 20 mA analog signal during normal operation, power failures, or faults. The loop resistance remains less than or equal to 250 ohms.
What is the level of electromagnetic isolation on the HART channels?
It features a three-terminal electromagnetic full quarantine between HART channels, as well as between the HART module and the host power supply. The electromagnetic quarantine voltage is not less than 1500 V.
Which HART protocols is this data collector compatible with?
The SM100-M-8 is compatible with HART protocol Ver5.0 and above.
