| the pci-1760 relay actuator and isolated d/i card is a pc add-on card for the pci bus. it provides 8 opto-isolated digital inputs with isolation protection of 2500 vdc for collecting digital inputs in noisy environments, 8 relay actuators for serving as on/off control devices or small power switches, and 2 isolated pwm (pulse width modulation) outputs for users specific applications. for easy monitoring, each relay is equipped with one red led to show its on/off status. each isolated input supports both dry contact and wet contact so that it can easily interface with other devices when no voltage is present in the external circuit. |
