Ling Hua Data acquisition card PCI7250 digital I / O card
Linghua Technology PCI-7250 / 7251 provides 4-channel SPDT (Type C) and 4-channel SPST (Type A) relay output and 8-channel isolated digital input.The LPCI / LPCIe-7250 and cPCI-7252 provide an 8-channel SPDT (Type C) relay output and an 8 / 16-channel isolated digital input.Each relay status is displayed by the onboard LED light.When the relay is in the position (SET) state, the corresponding LED light will light on, and otherwise, it will turn off.All digital input channels are nonpolar, radiophotic, and can be set to turn on / off the RC filters.This product is suitable for collecting digital input in a noise environment.
The PCI-7251 is an 8-channel relay output and an 8-channel isolation digital input extension card of the PCI-7250.All I / O features of PCI-7251 are the same as those for PCI-7250.The PCI-7251 must be used with the PCI-7250 and the control of the PCI-7250 controls the bus interface.One PCI-7250 card * * * can be connected to three PCI-7251 cards, and the DIO of PCI-7250 can be expanded from eight to 32 larger * * *.
