The upgraded OPTW-100 optically isolates data signals from two different Wiegand devices. It is commonly used to connect 2 Wiegand readers to 1 Wiegand port on an access controller, or connect 2 Wiegand readers to 1 Wiegand panel, with each credential read being sent to both panels. The updated OPTW-100 can be powered with 5-16Vdc. Also available is the CVX-OPTS intelligent splitter.
