PMC-OPTO32A 32 Optically Coupled Channels 24 Inputs, 8 Outputs Features Include: • 24 optically isolated inputs • Selectable input voltage range thru use of field replaceable bias resistors. • 8 optically isolated outputs - 4 normal current, 4 high current • Software Programmable clock debounce rate • Software Programmable Change of State detection. Rising edge or falling edge per input channel • Software Programmable Interrupts on any or all Change of State bit(s) • Software Pre-loadable Event counter on Input Bit 23 • Programmable Interrupt on event counter overflow • Built in Self-Test Features. • Programmable Little Endian / Big Endian swapping • PCI cycles Asynchronous to local bus cycles • Software Programmable board base address • VxWorks™ driver available Functional Overview: The PMC-OPTO32A board has 32 optically-coupled digital I/ O channels consisting of 8 outputs and 24 inputs. Each channel is electrically isolated (1000 Volts) from the PMC host processor board. Change-of-State Interrupts allow for an interrupt to the PMC host to be generated from any level change on any input. Built-in-self-test, selectable debounce times, input pulse counter, and I/ O voltages to 50 Volts makes for a versatile digital interface board. The board is a single PMC board, which complies with the PMC electrical interface IEEEO 1386.1. Both VxWorks and Windows NT drivers are available.
