DI5241SAP240000R0001
ABB DI524 expands an AC500 or AC500-eCo control station with 32 dedicated 24 VDC digital inputs. The plug-in electronic module works with a TU515 screw terminal unit or TU516 spring terminal unit and can serve central or distributed S500 I/O arrangements.

| 01 | Channel density | Thirty-two digital input points concentrate machine-state sensing in one S500 module. Typical signals include pushbuttons, limit switches, proximity sensors, auxiliary contacts and status relays. |
| 02 | Input thresholds | The 24 VDC inputs follow Type 1 behavior. A voltage from +15 to +30 VDC is interpreted as logic 1; the intermediate band between +5 and +15 VDC is undefined and should be avoided. |
| 03 | Input timing | The input delay is typically 8 ms and can be configured from 0.1 to 32 ms. Filtering can suppress contact bounce or noise, but the selected value also affects response time. |
| 04 | Current behavior | At 24 VDC, each input draws approximately 5 mA. Field-device leakage current, sensor type and shared commons must be checked against the input thresholds. |
| 05 | Mechanical system | DI524 is a plug-in electronic module and requires a compatible TU515 or TU516 terminal unit. The terminal unit remains part of the installed wiring architecture. |
| 06 | System placement | The module supports central AC500 / AC500-eCo expansion and distributed arrangements through compatible communication interface modules. Hot-swap capability depends on the terminal-unit arrangement. |

| 01 | DI524 1SAP240000R0001: What must be matched before replacing DI524 1SAP240000R0001? | Confirm the full order code, module revision, TU515 or TU516 terminal unit, channel allocation, commons, input voltage and project configuration. |
| 02 | DI524 1SAP240000R0001: Can DI524 1SAP240000R0001 drive output loads? | No. DI524 contains 32 dedicated digital inputs. A digital output or configurable I/O module is required for actuators. |
| 03 | DI524 1SAP240000R0001: How should the DI524 1SAP240000R0001 input filter be selected? | Use a short delay for faster sensors and a longer delay where contact bounce or electrical noise is present, while preserving the required machine response time. |
| 04 | DI524 1SAP240000R0001: Can DI524 1SAP240000R0001 be hot swapped? | Hot-swap capability depends on use with the applicable hot-swap terminal unit and the approved system procedure. The terminal base and controller state must be checked first. |
| 05 | DI524 1SAP240000R0001: Why does the DI524 1SAP240000R0001 terminal unit matter? | The electronic module and terminal unit form one installed assembly. The base determines field landing style and supports the wiring retained during module service. |
