Technical Specification:

HART Features

• Single HART channel supporting up to 13 devices (with internal 270Ω resistor) or 15 devices (with external 250Ω resistor).
• HART 7 compliant, fully backward-compatible with HART 5 and HART 6.
• Built-in HART communicator functionality for easy device scanning and discovery.
• Flexible resistor options: Supports both internal and external sampling resistors.
• Advanced diagnostics: Enables monitoring and debugging of HART commands.
• Free configuration tool: Easy setup using the SST-HT-CFG software.

Modbus Features

• Connects to a Modbus master; supports the following function codes: 0x03, 0x04, 0x06, and 0x10.
• The Modbus side can use either function code 0x03 or 0x04 to read data.
• The RS-485 port can be configured in transparent mode to enable transparent data transmission with the HART channel.

General

• Power supply: 24VDC (range: 9–30VDC), 80mA @ 24VDC.
• Operating temperature: -40°C to 70°C (-40°F to 158°F).
• Humidity: 5% to 95% RH (non-condensing).

Physical Features

• Dimensions (W × H × D): 1 in × 4 in × 3.5 in (25mm × 100mm × 90mm).
• Mounting: 35mm DIN rail.
