Features:
- Processes up to sixteen fixed 24 VDC digital field inputs.
- Optically isolates every input channel from the module logic.
- Operates in the documented 0 to 70°C HR Series ambient range.
The exact configuration is SPDSI13, the ABB Symphony Plus HR Series digital-input module with sixteen fixed 24 VDC channels.
It converts isolated on/off field states into data for the associated Symphony Plus controller while drawing power from the 5 VDC system bus.
Before installation, verify field voltage, channel polarity and commoning, HR Series slot and controller database so the fixed 24 VDC design is preserved.
Availability is subject to Apter Power inventory and sourcing confirmation.

- Collects 24 VDC contact and status signals for a Symphony Plus controller.
- Monitors sixteen optically isolated field inputs in an HR Series I/O cabinet.
- Replaces an installed fixed-voltage SPDSI13 while preserving the existing 24 VDC channel design.
- The module reports up to sixteen discrete field states to the Symphony Plus controller.
- Each channel operates from a fixed 24 VDC field input drawing 5.5 mA.
- Controller configuration maps each isolated input to its assigned process indication or logic point.
- Isolate field power before disturbing 24 VDC input conductors.
- Verify polarity and the documented common arrangement before energizing a replacement module.
- Do not apply the 48 VDC or 120 VAC ratings belonging to other SPDSI variants.
- ABB specifies an ambient operating range from 0 to 70°C.
- Cabinet ventilation must keep the module within that temperature range at full channel loading.
- Environmental conditions must remain within the limits of the complete Symphony Plus HR Series enclosure.
