M.2 Card with 8 OR 4 Isolated Digital Inputs with Change-of-State (COS) Detection and Solid State FET Relay Outputs

The M.2-IDIO-8 consists of a 2260/2280 sized M.2 Card interface board that connects to a Mobile-ITX-sized, DB-37M Isolation Module via an included 9 cable. That module is designed to be easily panel-mounted in any application environment. It uses the high speed PCI Express bus to transfer digital data to and from the card. The digital I/O is compatible with 8255 PPI chips making it easy to program. This allows for simple and trouble-free migration from other ACCES PCI and PCI Express digital I/O cards, but also provides for advanced features enabled by the onboard FPGA logic.

The M.2-IDIO cards are well suited to complex environments, mitigating otherwise challenging ground-loops, high-common-mode, and transient voltage spikes common in electrically-noisy industrial or factory locations. The broad voltage compatibility and high current outputs allows use in a wide range of applications.

The non-polarized inputs support both AC and DC, and configuration jumpers allow 4.7ms input filters to be enabled per-channel, as desired “ required for AC use. The isolated inputs support voltages from 3 to 31 VDC/VAC RMS [40Hz to 10000Hz], as well as standard 12/24 AC control transformer signals.

The outputs are fully protected High-Side Power MOSFETs capable of switching from 5 to 34VDC at up to 2A continuous-current load with 10A max current allowed (VBB0 = 5A, VBB1 = 5A).

Change of State (COS) detection and interrupt capabilities are designed to relieve software from polling routines that can consume valuable processing time. Each port can be programmed for detecting state changes on their lines, in which any changes of the enabled port™s bits (low-to-high or high-to-low) will generate an IRQ. An ISR (interrupt service routine) then determines which bit changed state and clears the interrupt.

Digital Features

Digital Features (read as œDigital Integration Features) are a new family of features available for applicable models of ACCES™ PCI Express (PCIe) and M.2 Card (mPCIe) Digital I/O product lines.

All the cards share features such as memory mapped registers for low-latency operation. Output channels support pulse/train / PWM / frequency / and quadrature generation. Inputs channels support flexible measurement of pulse duration, frequency, and event counting, with optional debouncing, IRQ generation, and more.
