FF expansion module FLC18E-8DI-8TN — I/O extension module 8 digital inputs, 8 transistor outputs

FF expansion module FLC18E-8DI-8TN is an I/O extension module that provides eight digital inputs and eight transistor outputs to increase the connection capacity of automation systems. The module is intended for integration into compatible control panels, PLC racks or machine controllers to expand discrete signal acquisition and control points. Typical functions include monitoring sensor contacts, reading discrete status signals and switching low-power loads such as indicators or small actuators.

Advantages

The module offers a compact way to add both inputs and transistor outputs without reconfiguring the main controller chassis. With separate digital inputs and transistor outputs, it supports straightforward wiring of sensors and actuators and helps centralize discrete I/O in one extension unit. Designed for industrial environments, the module minimizes the need for additional interface modules and simplifies system expansion while maintaining predictable response for discrete events.

Suitable for

• Expanding digital input capacity for PLCs and machine controllers
• Adding transistor outputs for driving indicators, relays (via intermediate devices) or small actuators
• Discrete signal acquisition in conveyor, packaging or assembly line applications
• Integration into control panels and distributed I/O racks

Key specifications

• Digital inputs: 8 channels for discrete contact or sensor signals
• Transistor outputs: 8 channels for low-power switching
• Form factor: I/O expansion module designed for mounting in compatible racks or panels
• Signal type: discrete (digital) input and transistor (PNP/NPN or open-collector style depending on system wiring)
• Typical uses: input monitoring, event detection, and driving indicators or low-power loads

How to use

Install the FF FLC18E-8DI-8TN module into a compatible expansion slot or mount it into the control panel according to the host system's installation instructions. Connect the digital input lines from sensors or contact outputs to the designated input terminals and wire loads or indicators to the transistor output terminals, observing correct polarity and protective circuitry as required. Configure the host controller or I/O mapping so that the additional inputs and outputs are recognized and assigned to the correct process variables or control logic.

Usage recommendations

Verify compatibility with the main controller and observe recommended wiring practices, including surge protection and proper grounding. Use the transistor outputs for low-power devices or through appropriate driver stages for larger loads, and consult the host system documentation for addressing and configuration procedures.
