- 16 discrete digital outputs for documented 24 VDC and 48 VDC field circuits
- Supports field-powered or system-powered Harmony Rack termination arrangements
- ABB documents SPDSO14 as the Harmony Rack evolution option for IMDSO14
IMDSO14 is an ABB Harmony Rack digital slave output module that provides 16 discrete output channels for controlling DC field devices.
ABB documents 24 VDC and 48 VDC output service for IMDSO14. Termination selection determines the available wiring and power arrangement: NTBMA2 provides 16 field-powered outputs, NTBMB2 provides 16 system-powered outputs, and NTBMB4 provides 14 system-powered outputs.
Before replacement or system evolution, identify the installed termination unit, output voltage, field-power arrangement, channel allocation, cable connection and controller configuration. ABB identifies SPDSO14 as an evolution option, but the existing wiring and termination design must be reviewed before migration.
Availability, condition, price, and shipping time for IMDSO14 are confirmed during quotation.

- Field-powered and system-powered termination arrangements are documented separately
- The original 24 VDC or 48 VDC design and output polarity must be retained
- Return wiring and protective devices must be checked with every output circuit
- NTBMA2 supports sixteen field-powered digital outputs for IMDSO14
- NTBMB2 supports sixteen system-powered digital outputs for IMDSO14
- NTBMB4 provides a different fourteen-output system-powered arrangement and must not be assumed equivalent
- ABB identifies SPDSO14 as the Harmony Rack replacement for IMDSO14
- IMDSO14 uses function code 83 in ABB's evolution mapping
- Verify the installed NTBMA2, NTBMB2 or NTBMB4 termination arrangement before migration
- Discrete 24 VDC actuator and interposing-relay control in Harmony Rack systems
- Discrete 48 VDC field-load switching where the installed design supports that voltage
- Legacy INFI 90 and Harmony digital-output replacement with controlled point testing
