Highland Technology has introduced a new VME product, the model V280 Isolated Digital Input Module. The V280 features 48 individually isolated digital inputs, with programmable debounce times and extended overload protection. It will accept DC or AC inputs and includes glitch-catch capability.
Versions are available for 24 volt and 3.3/5 volt logic level inputs.
The V280 includes BIST self-test which transparently tests virtually the entire signal path, including the input sides of all opto-isolators.
