Safety Instructions
●
When working with the VME-DIO32-L follow the instructions below and read the manual carefully
to protect yourself from injury and the VME-DIO32-L from damage.
●
The device is a built-in component. It is essential to ensure that the device is mounted in a way
that cannot lead to endangering or injury of persons or damage to objects.
●
Do not use damaged or defective cables to connect the VME-DIO32-L.
●
In case of damages to the device, which might affect safety, appropriate and immediate
measures must be taken, that exclude an endangerment of persons and domestic animals and
property.
●
Current circuits which are connected to the device must be sufficiently protected against
hazardous voltage (SELV according to EN 60950-1).
●
The VME-DIO32-L may only be driven by power supply current circuits, that are contact
protected. A power supply, that provides a safety extra-low voltage (SELV) according to EN
60950-1, complies with these conditions.
●
The device must be securely installed in the control cabinet before commissioning.
●
Protect the VME-DIO32-L from dust, moisture, and steam.
●
Protect the VME-DIO32-L from shocks and vibrations.
●
The VME-DIO32-L may become warm during normal use. Always allow adequate ventilation
around the VME-DIO32-L and use care when handling.
●
Do not operate the VME-DIO32-L adjacent to heat sources and do not expose it to unnecessary
thermal radiation. Ensure an ambient temperature as specified in the technical data.
DANGER

materials is not permitted.
●
The operation of the VME-DIO32-L for medical purposes is prohibited.
Service Note
The VME-DIO32-L does not contain any parts that require maintenance by the user. The VME-DIO32-L
does not require any manual configuration of the hardware except of the configuration of the dip switches
and the rotary switch. Unauthorized intervention in the device voids warranty claims.

VME-DIO32-L
1 Overview
Figure 1: Block circuit diagram of VME-DIO32-L
The VME-DIO32-L offers a digital process interface containing 32 opto-isolated digital channels for
IOs, which are transferred into a process. 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 VMEbus interface is designed for addressing as A24 Slave and D16/D08(EO) transfer mode.
The digital output channels use a quad channel smart high-side power switch ITS4130Q and accept
an operating voltage range of 18 VDC to 32 VDC (24 VDC nominal voltage) with a nominal current
of 0.5 A per channel. Thecurrent of each channelis limited. Overvoltage and undervoltage protection
functions are integrated in the power switch.
The VME-DIO32-L is developed as light successor for VME-DPIO32/63140 (V.1607.04).
Compatibility in terms of design and interfaces is ensured, however therange of functions isreduced.
The I/O-interface is pin-compatible. Transparent reading and writing of the IOs is possible. Counter,
PWM operations, and generation of interrupts are not supported by the VMEDIO32-L.
The VME-DIO32-L comes with a green and a red LED in the front panel for each of the 32 I/O-
channels. All LEDs are located on the front panel. The green LEDs indicate the input status, and the
red LEDs indicate the output short-circuit of the individual channels.
To feed power supply for the output groups separately, the power adapter VME-DPIO32-P2VCC
can be used for VME-DIO32-L.
If a separate wiring of the output groups is not necessary, the adapter VME-DPIO32-P2VCC-3X is
an economic solution. It feeds power to three VME-DIO32-L installed side-by-side in three VMEbus
slots.
