Modbus level transmitter F170

RS-232RS-4854-20 mA

Product description
The F170 is a field-mount level indicator and monitor for continuous level measurement. It displays measured level/height and content on a clear dual-line display with dedicated bargraph. The unit accepts a (0)4–20 mA (HART transparent) level input, provides up to four configurable alarm outputs (low-low, low, high, high-high) with ignore function, and can drive acoustic or visual alarm devices. Communication options include Modbus (ASCII/RTU) over RS232/RS485 and a USB-C port for configuration. Robust aluminum or 316L stainless steel enclosures (IP65, IP67 / Type4X) and an operating range from -40°C to +70°C enable reliable field operation.

Advantages

• Continuous and accurate level indication with simultaneous numeric and bargraph presentation.
• Rugged field enclosures in aluminum or 316L stainless steel with IP65/IP67 / Type4X protection for outdoor and harsh environments.
• Consistent, easy configuration using the Fluidwell configuration structure to reduce commissioning time.
• Flexible mounting: wall, pipe, panel or directly on outdoor sensors.
• Dual-line display shows level/height, content, percentage filled, 4–20 mA input or alarm values.

Features

• Four user-configurable level alarms: low-low, low, high, high-high with optional ignore/clear functions.
• Dedicated bargraph representing level/height or content.
• Red flashing LED backlight for alarm indication.
• Customizable measurement units for level/height and content.
• Single level input: (0)4–20 mA (HART transparent).
• Analog output options: active, isolated (passive) or loop-powered retransmission of level/height, content or input.
• Up to four alarm outputs: passive transistors or heavy-duty mechanical relays.
• Full Modbus communication (ASCII/RTU) via RS232 / RS485 or isolated RS485.
• USB-C port for plug-and-play remote configuration.
• PC/laptop programming supported with free configuration software.
• Power supply options: 10–27V DC (basic), isolated 12–30V DC / 12–24V AC, or isolated 115–230V AC.
• Auto backup of all settings.

Applications

• Continuous level measurement, monitoring and retransmission of level or content signals.
• Field-mounted indicator for safe and hazardous area applications; suitable for rain, snow, dust, sandy or saline atmospheres.
• Wide ambient temperature range: -40°C to +70°C (-40°F to 158°F).
