Parker Hannifin vm24 manual Jumper Configuration, VM24 Jumpers

Jumper Configuration

The jumpers are used to configure the inputs for the I/O boards as sinking or sourcing. Each socket has its own corresponding jumper, allowing each board with inputs to be independently configured for sinking or sourcing.

Sinking Inputs:	Position 3 (shown)
	Jumps pull-up to Vi (pin 3)
Sourcing Inputs:	Position 1
	Jumps pull-up to Ground (pin 1)

The default jumper position when shipped from the factory is position 3, as shown below. The jumper positions only affect inputs on the VM24. Jumper position does not affect the outputs. Jumper position is irrelevant for SIM8-OUT boards.
