ABB TA5105-4DOT: AC500, digital output module
ABB TA5105-4DOT AC500-eCo digital output option board providing four 24 V DC transistor outputs rated at 0.5 A per channel for industrial PLC and machine control applications.
Why Choose the ABB TA5105-4DOT Digital Output Option Board?
The ABB TA5105-4DOT is a compact digital transistor output option board designed to expand the output capacity of compatible ABB AC500-eCo programmable logic controllers. It provides four 24 V DC transistor outputs, identified as O0 to O3, for controlling actuators, indicators, interface devices and other DC loads in industrial automation systems.
Designed for the ABB AC500-eCo automation platform, the TA5105-4DOT provides fast and reliable solid-state switching without the mechanical contacts associated with relay outputs. Each transistor output is rated at 0.5 A for resistive loads, making the board suitable for a wide range of machine control and automation applications.
The TA5105-4DOT uses a removable 7-pin spring terminal block with a 3.50 mm terminal pitch. Four yellow status LEDs provide immediate visual indication of output states, while the board's internal circuitry is powered through the connected CPU. A separate 24 V DC process supply is connected through the UP and ZP terminals for the digital outputs.
Key Advantages
- Adds four 24 V DC transistor outputs to compatible ABB AC500-eCo PLCs.
- Each output supports a 0.5 A nominal resistive load.
- Solid-state transistor switching is ideal for frequent switching applications.
- Four yellow output status LEDs provide clear indication of O0 to O3 states.
- Supplied with a removable 7-pin spring terminal block.
- Compact option-board format expands PLC functionality without requiring a separate external I/O module.
Key Features
- ABB AC500-eCo digital output option board.
- Four transistor digital outputs.
- 24 V DC rated output voltage.
- 0.5 A nominal current per transistor channel.
- Outputs identified as O0, O1, O2 and O3.
- Individual yellow LED indication for each digital output.
- Separate UP and ZP terminals for the 24 V DC process supply.
- Removable 7-pin spring/cable front terminal block included.
Reliable Transistor Output Expansion for AC500-eCo PLCs
Digital output option boards allow PLC systems to control additional field devices without requiring a separate external I/O module. The ABB TA5105-4DOT provides four solid-state transistor channels for switching 24 V DC loads according to the control program running in the connected AC500-eCo processor.
The transistor outputs are particularly useful for applications involving frequent switching of suitable DC devices. Each channel has an individual status LED for straightforward commissioning and diagnostics. The outputs are not internally protected against short circuits or overload, so appropriate external output protection should be incorporated into the control system design.
Typical Applications
- Industrial machinery and machine control systems.
- Solenoid valve and actuator control.
- Indicator and signalling equipment.
- Interface relay and contactor control.
- Conveyors and material handling equipment.
- Packaging and production machinery.
- Building services and process automation.
- OEM control panels using ABB AC500-eCo PLCs.
