PCIe-7442High-density isolated I/O board with built-in watchdog
- Manufacturer
PCIe-7442 is an isolated digital input and output board for the PCI Express bus, meant for applications where many discrete signals have to be handled from a single slot of the control PC.
Isolation is 1250 VRMS between channels and system, with 28 V voltage protection on the inputs. A 32-bit watchdog with a 10 MHz clock watches over execution, with a trip interval programmable from software.
