The PCI-1761 provides 8 opto-isolated digital inputs with isolation protection of 2,500 VDC for collecting digital inputs in noisy environments, 8 relay actuators that can be used as
a on/off control devices or small power switches.
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.
