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. Built in optical relays are used for each channel. This eliminates the need for external relay panels. They are ideally suited for stringent military and airborne applications. On-board relays isolate all the inputs, outputs and the VME bus from each other against all sorts of transients emanating from ground loops etc. The AT-VME-DIO provides 16 channels of isolated inputs and 16 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 upto 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 & Conduction-Cooled. 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.
