Installation Guidelines

  • Keyswitch Setting: Ensure the keyswitch on the terminal base is set to position 2 to match the 1794-OV32 module type before installation.
  • Mounting: Hook the terminal base onto a 35mm DIN rail. Align the module's alignment bar with the groove on the terminal base and press down firmly until the latching mechanism locks.
  • Flexbus Connection: Ensure the Flexbus connector is fully engaged to the left to establish communication with the adjacent adapter or terminal base.
  • Handling: Always handle modules with care, ensuring pins on the bottom are straight and free from debris.
  • Power: While FLEX I/O supports removal and insertion under power (RIUP), ensure the system environment is safe before performing maintenance.

FAQ

What is the primary function of the 1794-OV32?

The 1794-OV32 is a 32-point digital output module used to interface a controller with field devices such as solenoids, relays, or indicators in a 24V DC sinking configuration.

Is this module compatible with standard FLEX I/O terminal bases?

Yes, it is designed to mount onto standard FLEX I/O terminal bases, which provide the wiring termination points for the field devices.

What does the sinking output configuration mean?

A sinking output switches the negative side (common) of the load to ground, meaning the load is connected between the positive supply and the module output.
