The AT family of 6U VME Discrete I/O boards are designed to provide users with a high degree of reliability and flexibility to meet input-output requirements. The AT-VME-DIO boards provide an economical method for isolation and interfacing of I/O signals to the VME bus. Optical-relays, which are built-in, are provided for each I/O channel. These eliminate the expenses incurred due to the usage of external relay panels. They are ideally suited for stringent military and airborne applications.

 

On-board relays isolate all the inputs, outputs and the VMEbus from each other against all sorts of transients emanating from ground loops etc. The AT-VME-DIO provides 32 channels of isolated inputs and 32 channels of isolated outputs. The voltage levels supported are TTL and Open Collector voltages. Also available on the board are 2 serial asynchronous RS-422 channels. These have a programmable baud rate up to 115.2 k/Bauds.

 
Hardware

The AT-VME-DIO boards meet the VME 64x standard and are available in a 6U form factor. The boards are available in three variants – Commercial, Air-Cooled and Conduction-Cooled versions. It is designed to work in units meeting MIL-STD-461C for EMI/EMC and MIL-STD-810F for airborne applications. All the components used are of MIL grade quality as per airborne application requirements in the conduction-cooled version. Front panel and Rear I/O connectivity options are provided for commercial and air-cooled boards. Conduction-cooled boards are available with Rear I/O connectivity only.
