Features:
- Processes 16 optically isolated digital field inputs for Symphony Plus Harmony Rack sequence-of-events service.
- Supports selectable 24 VDC, 48 VDC, 125 VDC, or 120 VAC input operation.
- Operates on the I/O expander bus without decoding the system time-synchronization link.
The current ordering configuration is SPSED01, a Symphony Plus Harmony Rack Sequence of Events Digital Input Module identified by ABB.
SPSED01 acquires field contact changes and transfers their digital states through the I/O expander bus for sequence-of-events monitoring.
Before installation, verify the selected field voltage, termination wiring, expander-bus assignment, and coordination with the segment time-synchronization module.
Availability is subject to Apter Power inventory and sourcing confirmation.

- Acquires digital field transitions for sequence-of-events monitoring in Symphony Plus Harmony Rack control systems.
- Expands event-input capacity on an I/O expander bus segment that uses a dedicated SPSET01 timing receiver.
- Handles documented DC or AC contact-input services when each channel is configured for its connected field circuit.
- Processes 16 independent input states through an onboard 16-bit processor with dedicated program and data memory.
- Transfers current digital event states to the controller across the Harmony I/O expander bus.
- Leaves time-link decoding to the SPSET01 module while providing additional input capacity on the same segment.
- Integrates with the ABB Symphony Plus Harmony Rack controller and I/O expander-bus architecture.
- Allows up to 63 SPSED01 modules to share a segment with one SPSET01 time-synchronization module.
- Requires confirmation of the installed expander-bus arrangement and field termination before replacing an existing module.
- Operates across the documented ambient temperature range of 0 to 70 degrees C.
- Uses optical isolation on all 16 input channels to separate field circuits from module electronics.
- Supports configured 24 VDC, 48 VDC, 125 VDC, or 120 VAC field inputs according to the selected wiring arrangement.
