ABB DO561 S500-eCo Digital Output Module
The ABB DO561, also cataloged as the DO561 Digital Output Module, operates as a dedicated hardware component for discrete DC load control within AC500-eCo PLC platforms. Configured to transfer internal logical states into physical switching operations, the module commands up to 8 field actuators or solenoids via integrated transistor outputs wired in a 1-wire configuration across a single electrical group.

Industrial Control and Network Integration Technical Attributes
The hardware executes discrete switching through dense internal transistor matrices, matching the firmware flash compatibility criteria of the AC500-eCo processor series. The module directly couples with the internal system backplane, sending individual status updates while relying on the native bus velocity protocols to maintain deterministic timing.
When remote configurations utilize Profinet or EtherNet/IP deterministic networks, the module updates the output image table within microsecond intervals, minimizing propagation delays. Load switching draws from the 24 VDC process voltage applied across the UP and ZP terminals. To avoid internal channel damage during high-current anomalies or short-circuit transients, you must place an external 3 A fast-acting fuse in series with the process supply path.
Frequently Asked Questions
Q: What are the dynamic response times of the transistor outputs when switching states?
A: The hardware delivers an output turn-on delay (0 to 1) of 50 us and a turn-off delay (1 to 0) of 200 us, enabling quick execution for high-speed industrial applications.
Q: Is individual channel-to-channel isolation provided within the 8-point output block?
A: No, the 8 channels share a common reference potential within a single electrical group. The module provides galvanic isolation exclusively between that entire output group and the internal control logic.
Q: Can the DO561 be hot-swapped while the AC500-eCo backplane is powered?
A: No, hot-swapping this module is not permitted. System power and process supply voltage must be fully isolated before inserting or removing the module to prevent electrical damage or unexpected state execution.
Field Installation Guidelines
- DIN-Rail Mounting Stability: Mount the unit on standard TH35 symmetric DIN rails. Secure the bottom locking mechanism completely to prevent intermittent backplane connectivity from mechanical shock.
- Shielding and Grounding Standards: Terminate inductive load suppressors close to the actuator. Route the 24 VDC process supply through twisted cables and keep signal lines physically isolated from high-voltage AC motor wires.
- Terminal Block Integration: Use pluggable terminal connectors for field wiring interfaces. Ensure all wires are stripped to the correct length and secured to prevent high-resistance connection points.
- Convection Space Requirements: Maintain an unobstructed space envelope above and below the housing. If mounting vertically, lower the maximum operating limit to +40 deg C to offset diminished airflow.
