More Information

Overview Manuals Applications Monitoring Compatibility Operating Environment

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.
Description
SPSED01 is the ABB Symphony Plus Harmony Rack sequence-of-events digital input module that processes 16 optically isolated field inputs for documented DC or AC service.

The module communicates through the I/O expander bus and adds event-input capacity without decoding the time synchronization link assigned to the segment SPSET01 module.

Confirm field-voltage selection, termination wiring, expander-bus assignment, and the required SPSET01 timing arrangement before replacement or installation.

Technical notes
SPSED01 cannot decode the SPTKM01 time-synchronization link; retain one SPSET01 on the I/O expander-bus segment when synchronized event timing is required.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does SPSED01 process events without decoding the time-synchronization link?
SPSED01 reads 16 optically isolated inputs and transfers their states over the I/O expander bus; segment timing is supplied by the dedicated timing hardware.
How many SPSED01 modules can share one I/O expander-bus segment?
ABB documents up to 63 SPSED01 input modules on one segment when the required timing module is also installed.
When is SPSED01 appropriate for sequence-of-events monitoring?
Use SPSED01 when additional isolated event inputs are required on a correctly timed Harmony Rack I/O segment.
Which SPSED01 markings should be checked on an available spare?
Confirm the complete SPSED01 code, input-voltage configuration, module condition and traceability before accepting the spare.
Can SPSED01 replace a timing-capable event module without a design review?
No. SPSED01 does not decode the time-synchronization link, so the segment timing architecture must remain unchanged.
What should an SPSED01 documentation request include?
Request the ABB Symphony Plus product-catalog pages for SPSED01 together with the configured field voltage and I/O expander-bus details.
