FIT-4393 (FIT-4CH) – Flow Indicator Totaliser

Short description: A rugged microcontroller-based multi-channel flow indicator and totaliser with 4 analog inputs, 8-digit totalisers, 24VDC excitation supply, retransmission output, and RS485 Modbus RTU communication. Ideal for monitoring and logging multiple flow meters in industrial automation.

Key Features

• Ruggedised microcontroller-based system.
• Dual functionality selectable: Flow Rate indication / 8-digit flow totalising for all four flow inputs.
• Accepts four 4–20 mA DC linear inputs from flow transmitters (DPT with orifice assembly, rotameter, magnetic flowmeter, etc.).
• User configurable flow rate ranges and field settable flow totalising rates.
• Individual 8-digit totaliser for each flow input.
• Manual reset for totalisers.
• All programmable settings stored in EEPROM; totaliser values stored in battery-backed RAM.
• Built-in 24VDC, 100 mA excitation supply for powering flow transmitters.
• Optional 4–20 mA retransmission output for external indicators, recorders, or PLCs.
• RS485 communication port with galvanic and optical isolation, supporting MODBUS RTU protocol.
• Bright 7-segment LED display for instantaneous flow rate or totaliser value, selectable from front keys.
• Front-panel keys for display selection and programming.
• Compact panel mounting design (96 × 192 mm).
