It accepts up to 16 single-ended inputs or eight differential inputs. Inputs are protected against over-voltage conditions up to ±35 volts and typically survive static discharges beyond 4000 volts. Conversions can be initiated in any one of three ways: (a) software command, (b) external start commands, or (c) on a timed basis using on-board programmable counters. Converted data may be transferred to the computer by one of two software selected methods: (a) polling for the end-of-conversion signal, or (b) by generating an Interrupt when the end-of-conversion signal occurs.\u003c\/p\u003e\u003cp\u003eThe card includes a 4K Samples FIFO data buffer and a 4K words Point List FIFO buffer.

Further, by placing jumpers on the card you can manually select a 4-20 mA current range. In that latter case, the current input is converted to a special analog voltage range that will yield full 12-bit resolution and there can be up to eight inputs.

The same printed circuit board is used for all three models and is populated for 120 bits, 96 bits and 72 bits respectively. The card is 12.2 inches (310 mm) long and may be installed in any 5-volt PCI slot in IBM and compatible computers.\u003c\/p\u003e\u003cp\u003eThe cards are designed for industrial applications and should be installed in a long PCI slot of an IBM or compatible computer. Each I\/O line is buffered and capable of sourcing 15 mA or sinking 24 mA (64 mA on request). The card contains Programmable Peripheral Interface chips type 8255-5 (PPI) to provide computer interface to the digital I\/O lines. Each PPI supports three 8-bit groups A, B, and C. Each 8-bit group can be configured to function as either inputs or latched outputs. Group C can also be configured as four inputs and four output latches. The I\/O line buffers are configured automatically by hardware logic for input or output use according to the PPI control register direction software assignment.\u003c\/p\u003e\u003cp\u003eOutputs of the I\/O buffers are pulled up through 10K resistors to +5VDC. Outputs can be changed to pull down by jumper selection on the card. This pull-up\/pull-down arrangement assures that there are no erroneous outputs at power-up until the card is initialized by system software. The I\/O buffers may be tristated under program control.\u003c\/p\u003e\u003cp\u003eTwo I\/O Lines of each port can be used to interface User Interrupts to the computer. Interrupts of all ports (one per port) are OR'ed together and the Interrupt level is assigned by the system. I\/O wiring connections are via 50-pin headers on the board. Every second conductor of the flat cables is grounded to minimize the effect of crosstalk between signals.\u003c\/p\u003e\u003cp\u003eThe cards occupy up to 32 registers within the PCI address space. When the card is first installed, Windows will detect it as new hardware and assign it an IRQ number and base address. There are no switches to set or base addresses to assign, making it easy to use. You cannot set or change the card inchs base address, you can only determine what the system has assigned. The PCI Bus supports 64K of I\/O address space so your card inchs address may be located anywhere in the 0000 to FFFF range. \u003c\/p\u003e","brand":"Acces I\/O","offers":[{"title":"Default Title","offer_id":10319530819,"sku":"PCI-DIO-120","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0869\/5892\/products\/PCI-DIO-120_20Blank_1d33d669-dbd8-4b6b-98da-d2708e42585d.jpeg?v=1477302669"},{"product_id":"pci-dio-24d-pci-24-ch-digital-i-o-db37","title":"PCI-DIO-24D  -   PCI, 24-ch Digital I\/O DB37","description":"\u003ca href=\"http:\/\/accesio.com\/MANUALS\/PCI-DIO-24DH.PDF\"\u003eProduct Datasheet  \u003c\/a\u003e\u003cbr\u003e\u003cbr\u003e\u003cp\u003e\u003cb\u003eThis product is \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Restriction_of_Hazardous_Substances_Directive\"\u003eRoHS-compliant\u003c\/a\u003e\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003ePlease contact us if you require a non-RoHS version.\u003c\/p\u003e\u003cp\u003ePlease note, Acces I\/O products are often available in an array of different options, of which only a selection will be displayed here.

These inputs can accept either AC or DC signals and are not polarity sensitive. Input signals are rectified by photocoupler diodes while unused power gets dissipated thru a 1.8k-ohm resistor in series. The inputs may be driven by either DC sources of 3 to 31 volts (rms) or AC sources at frequencies of 40 Hz to 10 KHz. Standard 12\/24 AC control transformer outputs can be accepted as well. External resistors connected in series may be used to extend the input voltage range, however this will raise the input threshold range. Consult with factory for available modified input ranges.\u003c\/p\u003e\u003cp\u003eEach input circuit contains a switchable filter that has a 4.7 millisecond time constant. (Without filtering, the response is less then 40 microseconds) The filter must be selected for AC inputs in order to eliminate the on\/off response to AC. The filter is also valuable for use with slow DC input signals in a noisy environment. The filter may be switched out for DC inputs in order to obtain faster response. Filters are individually selected by jumpers. The filters are switched into the circuit when the jumpers are installed in position FLT0 to FLT15.\u003c\/p\u003e\u003cp\u003eOutputs\u003c\/p\u003e\u003cp\u003eThe board's outputs are comprised of eight FORM C SPDT electro mechanical relays.

For low profile systems please use P\/N LPCI-COM-1S for the card to be shipped with a low profile bracket.\u003c\/p\u003e\u003cp\u003eThe card supports RS-422 and RS-485 balanced-mode transmission\/reception. Each card has capability to add bias voltage. (RS-485 communication requires that one transmitter in the network must supply a bias voltage to ensure a known 'zero' state when all transmitters are OFF). Also, receiver inputs at each end of the network should be terminated to eliminate ringing. The card supports these options by means of jumpers on the card.\u003c\/p\u003e\u003cp\u003eType 16550 UARTs are used as the asynchronous communication elements. These include a 16-byte transmit\/receive FIFO buffer to protect against lost data in multi-tasking systems while maintaining 100 percent compatibility with the original IBM serial port.\u003c\/p\u003e\u003cp\u003eA crystal oscillator is located on the card and permits precise baud rate capability up to 115,200 baud. Higher baud rates, up to 460,800 baud, are achieved by changing a jumper on the card. The driver\/receivers used, type 75176, are capable of driving extremely long communication lines at high baud rates. They can drive up to ±60 mA on balanced lines and receive inputs as low as 200 mV differential signal superimposed on common mode noise of +12V to -7V. In case of communication conflict, the driver\/receivers feature thermal shutdown.\u003c\/p\u003e\u003cp\u003eWhen the card is first installed, the operating system will detect it as new hardware and assign it an IRQ number and base address. There are no switches to set or base addresses to assign, making it easy to use. From this point on, the card behaves as a standard COM port.\u003c\/p\u003e\u003cp\u003eRTS and AUTO TRANSCEIVER CONTROL\u003c\/p\u003e\u003cp\u003eIn RS-485 communications the driver must be enabled when needed and then disabled to permit all cards on the network to share a two-wire or four-wire cable. The card has two methods to control the driver: automatic (AUTO) and request-to-send (RTS) control. Under automatic control, the driver is enabled (and the receiver disabled) when data are ready to be transmitted. When transmission is complete, the driver remains enabled for the transmission time of one additional character and then is disabled. The card automatically adjusts its timing to the baud rate of the data. (NOTE: For use in half-duplex mode under Windows, the card must be operated in the AUTO mode.)
