SM100-HHE Series HART Intelligent Transmitter This industrial-grade device converts RS485 to HART protocol, supports MODBUS-RTU, and provides isolated HART channels for smart instruments (flow, pressure, temperature, etc.). It works with 12-24V DC, Bell202 FSK standard, and does not interfere with 4-20mA analog signals. Key capabilities: - ARM microprocessor + dedicated HART modem - Two RS485 interfaces (depending on model) - Transparent transmission mode or MODBUS-RTU - Each HART channel isolated - Configuration software included - Operating temperature: -20°C to +80°C Available variants (6 models) – choose by channel count and RS485 ports: SM100-HHE-S-1CH : 1 HART channel, Single RS485 (1 port) SM100-HHE-D-1CH : 1 HART channel, Dual RS485 (2 ports) SM100-HHE-S-2CH : 2 HART channels, Single RS485 SM100-HHE-D-2CH : 2 HART channels, Dual RS485 SM100-HHE-S-4CH : 4 HART channels, Single RS485 SM100-HHE-D-4CH : 4 HART channels, Dual RS485 Which to choose? - Single RS485 models (S) are cost-effective for most systems. - Dual RS485 models (D) allow independent parameter configuration and faster data exchange. - 1CH, 2CH, or 4CH – select based on how many HART instruments you need to connect.
- HART Protocol Communication – Supports Bell202 FSK standard, superimposes digital signals on 4-20mA analog loop without interference. Works with Yokogawa and other HART-enabled smart instruments.
- RS485 & MODBUS-RTU Support – Features two standard RS485 interfaces for parameter configuration. Converts HART data to MODBUS-RTU protocol for real-time data transmission.
- Multi-Channel Isolated Design – Available in 1, 2, or 4 channel models. Each HART channel is fully isolated to prevent cross-talk and ensure stable instrument current output.
- Wide Power & Temperature Range – Operates on DC 12-24V (ripple ≤200mV, current 100mA). Working temperature: -20°C to +80°C, humidity 10%-80% RH.
- Easy Configuration & Transparent Mode – Comes with dedicated configuration software for parameter setting. Supports transparent transmission mode for direct HART command reading.
