Physical Layout and I/O Arrangement

The Fuji FTU120C weighs 0.52 kilograms for sturdy mounting. Its 135 mm width fits standard sub‑panels easily. Eight digital inputs occupy the top terminal row. Six transistor outputs sit directly below them. Two analog channels reside on the right side connector. A lithium battery retains program data for up to five years. Additionally, a 1000 µF capacitor smooths supply voltage transients.

Programming and Memory Features

This PLC stores user programs in 8 KB of flash memory. The device retains data even after power loss. A capacitor‑backed RAM holds 2 KB of variable values. Therefore, critical counters and timers survive brief outages. The scan cycle reaches just 1.5 milliseconds per 1,000 steps. Consequently, this unit responds quickly to fast input signals.

Installation and Wiring Guidelines

Mount the Fuji FTU120C on a DIN rail or using M4 screws. First, disconnect all power sources before wiring. Then connect the 24V DC supply to the dedicated terminals. Wire each digital input to a sensor or push button. Attach loads to the NPN transistor outputs appropriately. Finally, use shielded cable for the analog inputs. Always separate high‑voltage wiring from low‑level signals.

Application and System Compatibility

This PLC works as a standalone controller or a remote slave. It communicates via RS‑485 Modbus RTU protocol. Typical applications include conveyor sorting and packaging machines. The unit also suits small pumping stations or fan controls. For larger systems, network multiple FTU120C units together.
