Hart Modem Hart turn USB modem with WiFi Hart cat

1.1 Product Brief

Sm100-c (III) is a Hart intelligent converter developed and produced by Jiaxing Pine Mao Electronics Co., Ltd. According to industry standards, and it can communicate with any manufacturer's Hart instrument, such as Rosemount, E+h, Siemens, Cologne, Yokogawa, Chuan instrument and so on. At the same time its shape is integrated design, easy to install and carry, using standard USB interface, serial bus power supply, so that users in the use of convenient and fast.

Because Sm100-c (III) Intelligent converters are designed for industrial product integration, special designs are used in temperature range, vibration, electromagnetic compatibility and interface diversity to ensure stable operation in harsh environments, providing high quality assurance for your equipment.

Can be used in high-altitude, chemical and other non-operating platform environment.

1.2 Product Performance

Supported operating systems for Windows XP, Windows7, Windows10.

Fully compatible with USB V1.1 and USB CDC V1.1 specifications.

Fully compatible with USB V2.0 and USB CDC V2.0 specifications.

USB bus powered (non-isolated cable), DC 5V DC 30mA.

Full transparent data conversion.

Compatible with any Hart protocol.

1.3 Product Features

Built-in isolated dc24v output provides power and communication to second-line instrumentation to minimize wiring.

The Hart signal is transmitted by means of an isolated transformer.

Built-in high-precision loop 250ω resistor, communication test, no additional resistance required.

With switch, can be converted with or without WiFi

The Panel has a light and the converter works at a glance.

1.4 Main Parameters

Physical size: The length of the MMX wide MMX high 20mm.

Working ambient temperature: -20℃~+80℃.

Relative Humidity: 10% ~ 80%.

1.5 Wiring Diagram

Communication line: Black USB cable (48cm) for sm100-c and PC communication, while the line to sm100-c power supply.

Test line: Red and black two wires (50cm) for sm100-c connection to Hart instrument.

Serial conversion switch: USB or WiFi two serial port conversion mode

dial to "USB" through the communication line with the PC communication, the communication line connected to the PC;

dial to "WIFI" through the virtual serial port and the PC communication, the communication line connected to the charger.

Hart Conversion switch: 250Ω, none, 24v/250ω three Hart conversion modes

dial to "250Ω" is the internal 250Ω resistor working state;

dial to "None" is not built-in 24V and 250ω resistance of the working State;

dial to "24v/250ω" is the built-in 24V and 250Ω resistors working state.

According to the actual situation, the conversion switch is dialed to the corresponding location, and then connected to the line.

① built-in 250ω resistor
