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.

- 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.
