Fuji FTU223B Output Module

Output Architecture and Switching Performance

The Fuji FTU223B delivers 16 discrete output points for controlling solenoids, contactors, and indicator lamps. Each output channel provides 2.0 Amps at 24 VDC with a total module rating of 32 Amps. This unit employs transistor output technology for high-speed switching applications. It operates effectively in assembly lines, conveyor systems, and automated machinery requiring robust output capacity.

This output module features individual channel protection against overcurrent and short-circuit conditions. Each channel automatically resets after fault conditions clear without manual intervention. Consequently, engineers can deploy this module in demanding environments with confidence in its reliability.

Physical Specifications and Mounting

The FTU223B measures 12.0 cm in height, 6.5 cm in width, and 10.5 cm in depth. It weighs approximately 0.32 kg, allowing for straightforward installation in standard Fuji racks. This module occupies a single slot on the baseplate and connects directly to the backplane power bus. The front panel features 16 LED indicators that display the real-time status of each output channel. These visual indicators simplify troubleshooting and reduce maintenance downtime significantly.

A removable terminal block accommodates all field wiring connections for the 16 output points. This terminal block accepts wire sizes ranging from 0.2 to 2.5 mm² (24 to 14 AWG). The module also includes dedicated terminals for connecting external power to the output field circuits.

Power Consumption and Energy Storage

This output module draws 150 mA from the backplane at 5 VDC for internal logic operation. It requires an external 24 VDC supply rated at 32 Amps to power the output field circuits. The module incorporates energy storage capacitors that maintain output states during brief power interruptions. These capacitors provide approximately 8 milliseconds of hold-up time to prevent nuisance fault reporting.
