Advantech Isolated digital I/O cards with digital filter
The PCIe-1730H and PCIe-1756H digital I/O cards include a digital filter function, which helps reduce or eliminate noise and chatter input signals. The filters can be applied to all input terminals and may be used as interrupts with the settings applied in the software. The PCIe-1730H offers 16 isolated digital input channels, 16 isolated digital output channels with isolation protection of up to 2,500 Vdc and 32 TTL digital I/Os. All input signals can be used as interrupts. The PCIe-1756H features 32 opto-coupler isolated inputs (for use with current sink outputs) and 32 isolated outputs, with all the inputs having the interrupt function.
