Module fit in the distributed I/O slice
The 1SAP440000R0001: This 32-channel module grabs 24 VDC signals into the ABB distributed I/O rack. It draws 5 mA per input, so dry contacts see negligible load. The supply range is 20.4…28.8 V DC — keep bus voltage within that window, especially on long cable runs. Input delay trims from 0.1 ms to 32 ms, which helps debounce noisy field wiring.
