ABB / AC500 S500-eCo 24 V DC mixed I/O module
ABB DX561 8-Input 8-Output Transistor Digital Module
Eight 24 V DC inputs and eight 0.5 A transistor outputs arranged as separately isolated input and output groups.
01
Product Identification
ABB DX561, article 1TNE968902R2301, combines eight 24 V DC digital inputs with eight 24 V DC transistor outputs. The input and output channels form two separately isolated groups and use removable 9-pin and 11-pin terminal blocks.

Functions
- Reads eight 24 V DC field signals in one isolated input group.
- Drives eight 24 V DC loads through 0.5 A transistor outputs in a separate group.
- Provides one yellow state LED for every input and every output.
- Separates input, output and internal electronics domains galvanically by group.
- Uses removable terminal blocks so field wiring can remain organized during service.
04
Applications
- Compact AC500-eCo stations requiring balanced eight-input and eight-output capacity.
- 24 V DC sensor and actuator wiring with transistor output switching.
- Control panels that benefit from separate isolation between the input and output channel groups.
- Replacement of article 1TNE968902R2301 while retaining the field terminal arrangement.
- Distributed I/O configurations supported by the documented S500-eCo interface modules.
05
Lifecycle
- ABB lists DX561 article 1TNE968902R2301 in the Active lifecycle phase.
- Record the selected 9-pin and 11-pin terminal-block styles because they are separate ordering items.
- DX571 is a relay-output module and is not a transistor-output replacement.
- Provide the documented external output protection and maintain natural-convection clearance.
- Verify all sixteen status indications and both isolated groups after maintenance.
