Introduction PAD64 DIO-AIO Conversion Set is the equipment which could be used for DI/DO (Digital input / Digital output) conversion and galvanic isolation between Real-time simulation system and protection equipment, and any other equipment which need AIO (analog binary input/output, dry contacts). Through the PAD64, the tripping contacts of the protection relay and automation device (dry contacts, or wet contacts) could be converted into a photoelectrically isolated 0V-5V level signal, and the digital simulator's digital binary output could be converted from 0V-5V level signal into dry contacts. One PAD64 chassis can be freely configured with a maximum of 4 modules, and the digital input and digital output can be configured arbitrarily. The configuration of a single module is either 16 channels of binary input or 16 channels of binary outputs. Users could select the suitable modules to install in the PAD64's chassis for the application use.
