More Information

Overview Manuals Applications Operating Environment Diagnostics Installation

Features:

  • Provides sixteen fixed 48 VDC digital input channels for HR Series control systems.
  • Uses optical isolation on each input to separate field signals from module logic.
  • Draws approximately 95 mA from the 5 VDC module supply under documented conditions.
The current product is SPDSI14, the ABB Symphony Plus HR Series 48 VDC digital input module.

It collects discrete equipment states for control, alarm, sequence, and operator-monitoring functions.

Before replacement, verify the exact 48 VDC field design, rack and slot assignment, wiring, 5 VDC power capacity, and supported system configuration.

Availability is subject to Apter Power inventory and sourcing confirmation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • Receives motor, valve, breaker, permissive, and equipment-status contacts wired for 48 VDC operation.
  • Supplies discrete states to alarm, interlock, sequence, and operator-display logic in process-control systems.
  • Maintains installed HR Series input assignments where the rack, voltage, and termination design remain compatible.
  • Carries a published ambient operating range from 0 to 70°C.
  • Requires the cabinet environment to remain within the documented temperature envelope during service.
  • Places sub-zero or above-70°C applications outside the published operating range and requires alternate qualified hardware.
  • Presents sixteen digital field states to the controller for operational and alarm-status monitoring.
  • Uses optical isolation to separate field-input disturbances from the module logic interface.
  • Directs troubleshooting to the 48 VDC source, field wiring, termination, rack power, and controller status before module replacement.
  • Requires confirmation that every connected field circuit uses the fixed 48 VDC input design.
  • Needs available 5 VDC rack power for the documented 95 mA typical module demand.
  • Must match the supported HR Series rack position, termination wiring, and control-system configuration.
Description
SPDSI14 is the ABB Symphony Plus HR Series digital input module for sixteen fixed 48 VDC field signals.

Each channel uses optical isolation between the field circuit and module logic, allowing the control system to acquire discrete equipment states while maintaining electrical separation.

The module is rated for a 0 to 70°C ambient range and uses 5 VDC module power. Verify the fixed 48 VDC field design, rack assignment, wiring, and supported system configuration before replacement.

Technical notes
SPDSI14 is fixed at 48 VDC; verify each field circuit before replacing or substituting this input module.

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.
Where is SPDSI14 used in a Symphony Plus system?
It receives 48 VDC discrete field states for control, alarm, and equipment-status monitoring in HR Series installations.
Can SPDSI14 replace a digital input module with a different field voltage?
No direct substitution should be assumed because SPDSI14 is the fixed 48 VDC version; verify every connected circuit first.
What should be investigated when SPDSI14 does not report a field state?
Check 48 VDC field power, signal wiring, channel termination, rack power, controller status, and the actual field contact.
Does optical isolation make SPDSI14 channels interchangeable with every signal type?
No. Isolation separates field and logic circuits, but the module remains specified for fixed 48 VDC digital inputs.
What installation details must match during SPDSI14 replacement?
Confirm the exact code, rack and slot assignment, field-voltage design, termination wiring, module power, and supported system configuration.
How should buyers request SPDSI14 availability?
Provide the exact SPDSI14 code, required quantity, destination, and installed Symphony Plus or Harmony configuration.
