The T760 converts two digital fiberoptic inputs into high-level isolated electrical pulse outputs. Each optical input has an individual digital threshold trimpot, analog signal monitor, and threshold test point, allowing optimum setting of receive thresholds.
Digital outputs are transformer isolated. A single trimpot, with test point, sets the digital output levels from 5 volts to 80-100 volts peak.
Electrical outputs directly follow optical inputs.
Highland also offers the T750, a 4-channel high-voltage transformer-isolated pulse driver.
