• Accepts eight 24 V AC or DC field signals in one compact S500-eCo position.
• Supports source, sink and AC Type 1 input arrangements.
• Uses one byte of input process data for straightforward controller mapping.
• Provides one yellow status LED for each channel.
• Operates from the station I/O bus without a separate module power connection.
• Uses a removable nine-pin terminal block selected for screw or spring wiring.

• Small sensor groups in compact AC500-eCo control panels.
• Machine upgrades requiring either 24 V DC or 24 V AC input sensing.
• Distributed I/O stations attached to supported S500 communication interfaces.
• Applications where pluggable field termination simplifies electronics service.
• Active spare coverage for DI561 article 1TNE968902R2101.

• ABB lists the exact DI561 article as Active.
• The compatible nine-pin terminal block is ordered separately.
• Hot swap is not supported for DI561; remove voltage before module or terminal work.
• Record the source, sink or AC wiring method before replacement.
• Validate all eight channel states after recommissioning.

Can DI561 accept both AC and DC input signals?

Yes. ABB specifies eight inputs for 24 V DC or 24 V AC.

How are the DI561 inputs grouped?

All eight channels form one input group that is isolated from the module logic.

Does the module require an external supply connection?

No separate module supply connection is needed; its circuitry is powered through the I/O bus.

What terminal block is required?

DI561 uses one nine-pin S500-eCo terminal block, ordered separately.

Is DI561 suitable for hot swapping?

No. ABB states that hot swap is not supported for this module.

How much process data does DI561 use?

The eight inputs occupy one byte of input process data.
