The 57419-1B 32-Channel Input Module is a 32-point digital DC input block designed for Reliance Electric Automax PLC systems (often cataloged as O-57419). It accepts low-level DC field signals in the 5-24 VDC range, translating each channel into a PLC input bit for reliable status monitoring across up to 32 sensors or switches. In listings and cross-references, the same part appears as 57C419 or 57419-1B with a J-3632-2 designation, reflecting its place in the Reliance lineage of industrial I/O modules.
