The Allen-Bradley 1746-OV32 is a 32-channel DC sinking discrete output module designed for the SLC 500 PLC system. It provides 32 DC transistor outputs that sink current and operates on a 5 to 50 V DC supply, intended for use in a 1746 I/O backplane within a SLC chassis. This module is used to switch DC loads such as relays, solenoids, or indicator lamps; Rockwell notes that the 1746-OV32 is discontinued as of November 24, 2022.
