TA5105-4DOT extends a compatible AC500-eCo V3 processor with four non-latching transistor outputs in one electrically isolated group. Each channel is designed for 24 V DC loads up to 0.5 A.

The seven-pin removable terminal carries outputs O0 through O3 together with the UP process supply and ZP reference. Four yellow LEDs indicate the commanded output states when the required module and process supplies are present.

The option board adds a compact group of standard digital outputs directly at the processor. The CPU supplies the board logic, while UP and ZP provide the external process supply for the output stage.

Output LEDs provide channel-state indication, but the load circuit still depends on correct process power, external protection and application wiring.

• Install only in an AC500-eCo V3 processor option slot that supports TA5105-4DOT.
• Use the full model and order code because TA5105-4DOTW is a separate wide-temperature variant.
• Provide external short-circuit and overload protection because the outputs are not internally protected.
• Do not connect two outputs in parallel.
• Remove CPU and process power before mounting, removing or rewiring the option board.

• Switching four 24 V DC resistive or pilot-duty loads from an AC500-eCo V3 processor.
• Compact machine control where a small local output expansion is required.
• Output-state monitoring through the four front yellow LEDs during commissioning.
• Panel retrofits that retain a compatible CPU and need the same seven-pin terminal arrangement.
• Replacement of the standard TA5105-4DOT after the wide-temperature requirement and process-load current are checked.
