Why Choose the ABB TA5110-2DI2DOT Digital I/O Option Board?
The ABB TA5110-2DI2DOT is a compact digital input/output option board designed to expand the I/O capacity of compatible ABB AC500-eCo V3 programmable logic controllers. It combines two 24 V DC digital inputs and two 24 V DC transistor outputs in a single module, providing a space-efficient solution for connecting additional sensors, switches, actuators and other field devices.
Designed for the ABB AC500-eCo V3 automation platform, the TA5110-2DI2DOT supports both sink and source configurations for its two digital inputs. The two transistor outputs provide solid-state switching for 24 V DC loads and are rated at 0.5 A per channel for resistive loads, making the board suitable for compact machinery and industrial automation applications.
The TA5110-2DI2DOT uses a removable 7-pin spring terminal block with 3.50 mm pitch. Its internal circuitry is powered through the connected CPU, while a separate 24 V DC process supply is connected through the UP and ZP terminals for the transistor outputs. This combined input and output arrangement provides convenient local I/O expansion without requiring a separate external I/O module.

Compact Digital I/O Expansion for AC500-eCo V3 PLCs
Combined digital I/O option boards allow a PLC to monitor additional field signals and control additional devices without installing a separate external I/O module. The ABB TA5110-2DI2DOT provides two input channels for receiving 24 V DC signals and two transistor output channels for switching suitable DC loads according to the PLC control program.
The digital inputs can be configured for source or sink operation, providing flexibility when integrating switches and sensors. The solid-state transistor outputs are well suited to applications requiring frequent switching. Because the outputs are not internally protected against short circuits or overload, suitable external output protection should be incorporated into the control system.
Typical Applications
- Industrial machinery and machine control systems.
- Digital sensor and limit switch monitoring.
- Solenoid valve and actuator control.
- Indicator and signalling equipment.
- Conveyors and material handling systems.
- Packaging and production machinery.
- Building services and process automation.
- OEM control panels using ABB AC500-eCo V3 PLCs.
