SM101-D HART Modem, Industrial HART Communication Modem (RS232)

SM101-D HART Modem – Industrial HART Communication Modem Available with RS485 or RS232 interface. Compatible with Rosemount, E+H, Yokogawa, Siemens and other HART instruments.Product Overview The SM101-D is an industrial-grade HART modem designed for communication between a PC or controller and HART field devices. It supports bidirectional data exchange with any manufacturer's HART instruments, including Rosemount, E+H, Siemens, Yokogawa, Krohne, ABB and more. Ideal for configuration, calibration and monitoring of HART instruments.Two Interface Options - RS485 version (SM101-D-001): Suitable for long-distance, multi-drop networks. - RS232 version (SM101-D-002): Suitable for direct connection to PC serial port.Key Features & Benefits 1. Full HART Protocol Support Transparent data conversion, compatible with HART 5/6/7. No preamble or check byte needed for manual commands. 2. No External Resistor Required Built-in precision 250Ω loop resistor simplifies wiring for two-wire and four-wire instruments. 3. Easy Instrument Calibration Perform 4/20mA trim, zero trim, low/high point adjustment, and fixed current output mode directly from software. 4. Comprehensive Parameter Management Read/write device ID, tag, descriptor, sensor serial number, manufacture date, and short address. Configure range, units, damping, output characteristics. 5. Specialized Instrument Support Dedicated tabs for temperature transmitters (Rosemount 644/848T, E+H, Siemens, Yokogawa, ABB TTH200, Krohne TT50C) and differential pressure/multivariable transmitters (Rosemount 3051/300SMV, Yokogawa EJA). 6. Burst Mode Operation Enable burst mode for continuous data output using HART commands 1, 2 or 3.Technical Specifications Power Supply: DC 12~24V, <100mA, ripple ≤200mV Interfaces: RS485 (D+/D-) or RS232 (RXD/TXD/GND) HART Connection: LOOP+ / LOOP- (isolated transformer) Supported OS: Windows XP, 7, 10 Operating Temperature: -20℃ ~ +80℃ Relative Humidity: 10% ~ 80% Dimensions: 96mm × 80mm × 25mmPackage Includes 1 × SM101-D HART Modem (RS485 or RS232 version as selected) 1 × User Manual (digital download available)
