Product Overview

The SPDO-16 is a 16-channel isolated digital output expansion module for Samsung SSAS-Pro centralized alarm and monitoring control system, supporting seamless combination with RSPC-X32 main CPU and the full set of SSAS I/O modules including digital input (SPDI-24), analog input (SPAI-16) and temperature acquisition units. It converts logic commands issued by the master controller into physical switching signals to execute on-site equipment actions, such as starting/stopping water pumps, opening/closing pneumatic valves, triggering audible and visual alarms, and driving status indication lights on local mimic panels. Each independent output channel adopts opto-coupler isolation technology to isolate the internal control circuit from field loads, effectively blocking voltage surges and electromagnetic interference generated by inductive loads like coils. Front panel dedicated LED indicators directly display the ON/OFF working state of every channel, enabling technicians to quickly locate output faults and wiring abnormalities during routine inspection and troubleshooting. The modular stacked DIN rail design allows flexible expansion of digital control points according to project scale without modifying the main control rack structure.
