PICO-II8IDO4A 8 Isolated Digital Inputs, 4 Solid State Relay Outputs, and two 16-Bit Analog Inputs FEATURES • Pico-I/O™ USB device featuring SUMIT™ stacking connector 8 individually optically isolated digital inputs • Polarity insensitive AC/DC inputs accept up to 31VDC or AC RMS • Jumper selectable filtering per input channel for AC or voltage transients • Four optically isolated fully protected solid state high-side FET outputs • Outputs capable of switching from 5-34 VDC at up to 3A each • Two general purpose 16-bit A/D inputs • Up to 4 I/O expansion boards in SUMIT™ stack • Custom high-speed function driver • PICO-I/O™ module size (60mm x 72mm) & mounting capability FACTORY OPTIONS • Extended temperature • Microfit B or embedded Micro USB header connector • 4-20mA for analog inputs FUNCTIONAL DESCRIPTION The PICO-II8IDO4A is an ideal OEM USB solution for adding embedded reliable and robust multi-function I/O capabilities to any embedded computer supporting Pico-I/O™ and the SUMIT™ A connector. The Pico-I/O™ board standard (SFF-SIG: www.sff-sig.org) is the latest, smallest, stacking form factor for embedded I/O since the PC/104 standard. Up to four of the PICO-II8IDO4A can be mounted together. Featuring 4 solid state FET outputs, 8 optically isolated digital inputs and 2 high-resolution analog inputs, the unit is the smallest of its kind for multi-function control and monitoring using USB. The FET outputs can switch customer supplied voltages from 5 to 34V at UP TO 3A!. The outputs are de-energized at power-up to prevent an unintended control output signal. The output connections are available via a 16-pin IDC vertical header type connector. The digital inputs accept AC or DC signals as high as 32 volts and are interfaced via a 26-pin IDC type vertical header. The pinout allows a simple accessory cable to interface to one of the many available external screw terminal boards, or go cable-less and use a direct plug-in screw terminal like our TBK-26. Two analog inputs are also available on the 26-pin connector for a well-rounded multi-function compact PICO solution. The module draws all required power from the SUMIT™ connector of the SUMIT based embedded computer. The Pico-I/O™ size specification (4320 sq. mm) is exactly half of the PCB area of the popular PC/104 (8640 sq. mm) embedded board standard. The small size and easy connection makes the unit an excellent choice for a variety of embedded applications such as mobile, robotics, kiosks, and embedded medical and machine equipment. The PICO-II8IDO4A is designed to be used in rugged, industrial, and mobile environments and also has the option to be upgraded to extended temperature (-40°C to +85°C) specifications for military and defense applications. ACCESSORIES The PICO-II8IDO4A is available with optional cable assemblies, screw terminal boards and external signal conditioning boards. SOFTWARE The PICO-II8IDO4A utilizes a high-speed custom function driver optimized for a maximum data throughput that is 50-100 times faster than the USB human interface device (HID) driver used by many competing products. This approach maximizes the full functionality of the hardware along with capitalizing the advantage of high-speed USB 2.0. The PICO-II8IDO4A is supported for use in most USB supported operating systems and includes a free Linux and Windows 98se/Me/2000/XP/2003 compatible software package. This package contains sample programs and source code in Visual Basic, Delphi, C++ Builder, and Visual C++ for Windows. Also incorporated is a graphical setup program in Windows. Third party support includes a Windows standard DLL interface usable from the most popular application programs. Embedded OS support includes Windows Xpe. 10623 Roselle Street, San Diego, CA 92121 • (858) 550-9559 • Fax (858) 550-7322 • contactus@accesio.com • www.accesio.com April 23, 2010 BLOCK DIAGRAM SPECIFICATIONS Power Digital Outputs +5VDC Provided via SUMIT A connector with USB power Number: 4 switch limiting current to 500mA Type: N-Channel smart high-side switch Connector: 16-pin vertical IDC header Ordering Guide Switch levels: 5 to 34V PICO-II8IDO4A 8 Isolated Inputs, 4 solid state FET outputs and 2 Over-volt protection: 41V Current: 2A steady state, 3A peak for 50mS analog inputs module with SUMIT bus interface USBP-II8IDO4A 8 Isolated Inputs, 4 solid state FET outputs and 2 analog inputs module with USB micro-B and Digital Inputs micro-header interface connectors Number: 8 Type: Optically Isolated, non-polarized Model Options Connector: 26-pin vertical IDC header -T Extended temperature -40°C to +85°C Signaling: Powered, off below 3V, on from 3.1 to -I 4-20mA analog inputs 31VDC or ACrms Accessories Analog Inputs TBK-26 26-Pin female connector to screw terminal board Number of channels: Two, Single-Ended ADC Type: Successive approximation STB-26 Cabled termination solution, 26-Pin male header connector screw terminal board, DIN-rail Sampling Rate: 4k samples per second per channel Resolution: 16-bit mountable C104-26F-12 26-Pin female ribbon cable, 12” to connect Pico Unipolar range: 0-5V board inputs to STB-26 Current mode: 4-20mA factory option DIN-SNAP-6 6 inch length of snap-track with clips for mounting to DIN-rail, accepts one STB-26 Bus Type(s): USB 2.0 high-speed Only for use with USBP-II8IDO4A version USB 1.1 full-speed compatible CUSB-EMB-6 6’ USB cable type A to Micro-fit header connector Connectors: SUMIT A connector top and bottom Alternate interfaces: USB micro-B or micro-header or CUSB-Micro-B-6 6’ USB type A to type Micro B cable Environmental Operating Temp.: 0°C to 70°C (-40°C to +85°C factory option) Storage Temp.: -40°C to +85°C Humidity: Maximum 90% RH, without condensation.
