The ARM microprocessor, a HART protocol modem chip, and a great deal of real-world knowledge were used in the development of the SM100-W series HART smart converter. It offers great stability and dependability and is designed to meet the specifications of industrial items. To enable real-time data transmission, the intelligent converter has a standard RS485 interface and gateway that can either convert to MODBUS _ RTU/MODBUS _ TCP protocol to read data or transparently send 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. Digital and analog signals can be modulated and demodulated in both directions using the SM100 series intelligent converter.
It has a standard RS485 communication interface and gateway, which allows it to modify the communication baud rate, parity check bit, and settings. It increases the system's overall operating speed.
Equipped with specialized configuration software to adjust SM100-W series parameters and communicate with HART protocol instruments.
Supports standard MODBUS _ RTU and MODBUS _ TCP protocols for seamless industrial integration.
Multiple intelligent instruments using the HART protocol can be connected at the same time.
Isolation of each HART channel ensures instrument current output remains unaffected.
Data update time is 0.8 seconds for one set; updates in 6.4 seconds for eight sets.
Input DC 12 to 24 V, 100 mA. Ripple < 200 mA.
145 mm (L) × 90 mm (W) × 73 mm (H).
-20°C to +80°C.
10% to 80% RH.
It supports converting HART protocol to MODBUS _ RTU or MODBUS _ TCP protocols, or transparently sending data using the standard RS485 interface.
Yes, multiple instruments can be connected at once. Each channel is isolated, so the current output of individual instruments remains unaffected.
The data update time is 0.8 seconds for a single set. For a network of eight sets, the update time is 6.4 seconds.
The converter requires a DC voltage of 12 to 24 V and 100 mA current. Ensure the power supply ripple does not exceed 200 mA.
It supports two installation methods: fixed installation or standard regular rail installation for industrial environments.
The SM100-W series is built for durability, operating between -20°C and +80°C with a relative humidity of 10% to 80%.
