Features:
- Handles sixteen optically isolated open-collector outputs.
- Switches 24 VDC at 250 mA or 48 VDC at 125 mA per documented channel
- the module interfaces through the Harmony Rack I/O expander-bus architecture.
SPDSO14 is the ABB Harmony Rack 16-channel digital output module for sixteen optically isolated open-collector outputs.
It interfaces field signals with the Symphony Plus controller architecture and switches 24 VDC at 250 mA or 48 VDC at 125 mA per documented channel.
For SPDSO14, confirm the sixteen optically isolated open-collector outputs 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.

- Sixteen optically isolated open-collector outputs separate the field switching circuits from the internal rack electronics.
- Documented channel ratings are 250 mA at 24 VDC or 125 mA at 48 VDC for suitable loads.
- Inductive loads need appropriate suppression, and field protection must coordinate with the connected relay or device.
- NTDO02 termination or the approved relay interface must match the voltage, load type and installed wiring design.
- System compliance depends on the module, rack, enclosure, power supply and field circuits meeting the certificate conditions.
- Confirm the exact label and approval revision before using the output assembly in a classified location.
- Operate within the Symphony Plus noncondensing humidity limits and prevent moisture across open-collector field terminals.
- Cabinet sealing, heating and ventilation should avoid condensation during shutdown, restart and seasonal temperature changes.
- Allow the module and termination hardware to stabilize after storage before insulation and functional testing.
