SM100-G HART Intelligent Alarm Controller - China Suppliers & Factory for 4-20mA and MODBUS Protocol

Introducing the SM100-G HART Intelligent Alarm Controller, a cutting-edge solution designed with an ARM CPU and a HART protocol modem chip, backed by extensive real-world experience. This advanced controller ensures exceptional stability and reliability, tailored specifically to meet the rigorous demands of industrial applications, Featuring a standard RS485 interface, the SM100-G effectively reads data in the form of 4–20 mA current. It seamlessly communicates with intelligent instruments using the HART protocol, or converts data into MODBUS_RTU protocol, ensuring high compatibility and versatility. Real-time data tracking is a key feature, enabling prompt alarm actions when limits are breached, Utilizing the HART protocol, this instrument facilitates bidirectional data transmission without disrupting the 4 to 20 mA analog signal. By superimposing a modulated digital signal based on the Bell202 Frequency Shift Keying (FSK) standard, the SM100-G can efficiently modulate and demodulate signals in both directions, Manufactured in China, the SM100-G HART Intelligent Alarm Controller stands as a testament to quality and innovation from leading suppliers and factories in the industry. Upgrade your monitoring systems with this reliable controller today!
