FAQ

What is the primary function of the 1746-OV32?

The 1746-OV32 is a digital output module for the SLC 500 platform, used to control external DC-powered devices by sinking current to the common return.

Is this module compatible with all SLC 500 processors?

Yes, the 1746-OV32 is designed for the standard SLC 500 I/O chassis and is compatible with the SLC 500 processor family, provided the power supply can support the total current draw of the system.

What does current-sinking mean for this module?

Current-sinking means the module provides the path to common (DC negative) for the load. The load is typically connected between the positive voltage source and the module output terminal.
