1 Overview
In this manual the VME-DIO32-C and the VME-DIO32-F are described together as VME-DIO32.
The descriptions given in this manual apply to both versions, any differences are noted in the text
where they appear.

Block circuit diagram of VME-DIO32-C
The VME-DIO32-C offers a digital process interface containing 32 opto-isolated digital process I/O
channels. It includes all necessary components on a VMEbus 6U board and needs one slot.
The 32 digital I/O channels are programmable in 4 groups of 8 channels as inputs or outputs. The 4
groups are electrically isolated against the system and each other. An external voltage must be fed
individually for each group. The 32 input/outputs and the external voltages are connected to the 64-
pin connector P2.
The digital output channels use a quad channel smart high-side power switch ITS4130Q and accept
an operating voltage range of 12 VDC to 34 VDC (24 VDC nominal voltage) with a nominal current
of 0.5 A.
The current of each channel is limited. Overvoltage and undervoltage protection functions are
integrated in the power switch.
The VME-DIO32-C comes with a green and a red LED in the front panel for each of the 32 I/O-
channels. The green LEDs indicate the input status, and the red LEDs indicate the output short-
circuit.
