16-Channel HART Data Collector & MODBUS Protocol Converter | China Suppliers & Factory Solutions
Product Introduction
With the help of an ARM microprocessor, a HART protocol modem chip, and a great deal of real-world knowledge, the SM100-M-16 HART data collector was created. 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.
Product Features
- 16 HART devices can be connected simultaneously, and all HART channels set up for the HART data collector can be scanned both simultaneously and in parallel.
- Three-terminal electromagnetic complete quarantine between the host power supply and HART channels.
- The two-wire interface is used by every channel.
- The HART module's electromagnetic quarantine voltage must be at least 1500 V.
- The ability to separate HART signals (4–20 ma) is supported.
- Both RS485 and NET Ethernet interfaces must have a quarantine voltage of at least 1500 V.
- Use a modular design that isolates the HART module from the host and allows for online HART module replacement in any channel.
- An independent indicator light is supplied for each channel, indicating the communication status of the HART equipment and whether the equipment is online.
- Equipped with a communication interface, operation/fault indicator light, etc.
- Channel-wise data refresh rate ≥ 1 second.
- Support RS485 and Ethernet interfaces with a minimum speed of 100 Mbps.
- All HART devices' HART IDs can be read using proprietary HART commands.
- Support Telnet remote settings, as well as configuration and operating modes.
- Supports standard DIN rail installation and firmware program updates.
- When there is no power outage or malfunction and the loop resistance is less than or equal to 250 ohms, the equipment does not impact the accuracy or transmission of a 4–20 mA analog signal.
- It is compatible with HART protocol Ver5.0 and higher.
