Features:
- Handles sixteen optically isolated digital inputs.
- Allows each channel to be programmed for 24, 48 or 125 VDC or 120 VAC
- the module interfaces through the Harmony Rack I/O expander-bus architecture.
SPDSI22 is the ABB Harmony Rack 16-channel universal digital input module for sixteen optically isolated digital inputs.
It interfaces field signals with the Symphony Plus controller architecture and allows each channel to be programmed for 24, 48 or 125 VDC or 120 VAC.
For SPDSI22, confirm the sixteen optically isolated digital inputs range, termination unit, I/O expander-bus position, function code and field wiring before installation.
Availability is subject to Apter Power inventory and sourcing confirmation.

- The rack module is specified for operation from 0 to 70°C under the published Symphony Plus conditions.
- Cabinet airflow and module spacing must control local temperature around mixed-voltage input wiring.
- Prevent condensation after cold transport or storage and allow the assembly to stabilize before energization.
- Each of the sixteen channels is configured for the documented 24, 48 or 125 VDC or 120 VAC input class.
- Channel voltage, common wiring, threshold and termination must correspond to the field circuit and controller database.
- Universal voltage capability does not make unrelated terminations or mixed channel groups automatically interchangeable.
- Optical isolation supports separation between field-state circuits and the Symphony Plus rack electronics.
- Applicable approvals require the exact module, rack, enclosure and wiring combination identified by ABB.
- Certificate scope and installation requirements must be checked before use in hazardous or marine environments.
