Product questions
What is ABB 1SAP284000R0001 and how many inputs does it have?
It is the ABB DI581-S safety digital input module. It has 16 safety digital inputs for 24 V DC and eight test pulse outputs. The pulse outputs are intended for input testing, not general-purpose safety outputs.
What safety level can the DI581-S input configuration support?
The module supports up to SIL 2 with 16 single-channel inputs or up to SIL 3 with eight dual-channel inputs. The level achieved by a complete safety function depends on sensor wiring and the overall design; use ABB’s original safety manual to assess the application.
Does the DI581-S need a separate terminal unit?
Yes. ABB specifies a spring-type TU582-S terminal unit for the DI581-S; the terminal unit is ordered separately. Confirm the required parts and configuration before ordering.
Can the DI581-S be used with an AC500 controller or remote PROFINET I/O?
ABB describes local expansion at AC500 CPUs and remote expansion through CI501-PNIO, CI502-PNIO, CI504-PNIO or CI506-PNIO interfaces. This does not establish compatibility with every installation: provide the controller model, serial number and system configuration for verification.
