It connects directly to DB-16P, DB-16R, DB-24PR, DN-20 and DN-37 wiring boards.Software support covers Linux, DOS, Windows 98/NT/2000 and 32-bit Windows XP/Vista/7. A DLL and ActiveX control are provided, with sample programs for Turbo C++, Borland C++, Microsoft C++, Visual C++, Borland Delphi, Borland C++ Builder, Visual Basic and LabVIEW. The A-726 is a newer generation card designed to be fully compatible with the A-626, while the A-628 offers 8 AO channels.ApplicationsSignal analysisIndustrial automationLaboratory automationSensor interfaceFFT and frequency analysisTransient analysisProduction testProcess control

The A-726 CR is an ISA bus data acquisition card for engineers who need six 12-bit analogue outputs alongside 16 TTL digital inputs and 16 TTL digital outputs in a single PC slot. It is designed to be fully compatible with the A-626, so it can be used as a like-for-like option in existing ISA-based systems.Each D/A channel can be set individually by jumper to one of several output ranges: ±10 V, ±5 V, 0 ~ 5 V, 0 ~ 10 V, or 4 ~ 20 mA (sink). The reference circuit can use an internal -5 V or -10 V source, or an external reference of up to ±10 V, AC or DC. An on-board reference device is included to limit reference voltage drift with temperature.Software support covers DLL and ActiveX control, with sample programs for Turbo C++, Borland C++, Microsoft Visual C++, Borland Delphi, Borland C++ Builder, Visual Basic and LabVIEW. Driver support is listed for Linux, DOS, Windows 98/NT/2000 and 32-bit Windows XP/Vista/7.ApplicationsSignal analysisIndustrial automationLaboratory automationSensor interfaceFFT and frequency analysisTransient analysisProduction testProcess control

The ISO-DA16 CR is a 16-channel, 14-bit analogue output board for PC/AT compatible computers with an ISA bus. Each output has its own converter and optical isolation rated for up to 2500 Vrms common-mode voltage, which suits programmable voltage sources and programmable current sinks in process control and harsh environments.Output type (unipolar or bipolar) and range can be set in software across 0 ~ 5 V, ±5 V, 0 ~ 10 V and ±10 V. Each converter also provides a 4 ~ 20 mA current sink to ground, and the outputs use double-buffered D/A latches with command set programming.The board is jumperless and trimless. Calibration is carried out under software control with the data held in EEPROM, and the power-on value of each output can be pre-defined and stored on board. This ordering code includes one CA-4002 D-Sub connector.ApplicationsProgrammable voltage sourceProgrammable current sinkHarsh environment operationProcess control

ISO-DA16/S CR is an ISA bus card that provides 16 isolated, double-buffered analogue outputs for PC/AT compatible computers. Each channel can be configured in software as a voltage output or a current sink, so one board can serve as a programmable voltage source or a programmable current sink in the same system.Isolation is provided by a built-in DC/DC converter rated at 3000 VDC, together with 2500 VDC photo-isolation. Output type (unipolar or bipolar) and range (0 ~ 5 V, ±5 V, 0 ~ 10 V or ±10 V) are set in software, and calibration is also performed in software with the data held in EEPROM, so no trimpots or jumpers need adjusting.The board also includes 16 digital inputs, 16 digital outputs at 5 V/TTL levels and three 16-bit timer/counter channels. It is supplied with a DN-37 terminal board and a CA-3710 D-Sub cable. Engineers working on process control or harsh-environment installations within the 0 ~ +60 °C operating range will find the board suited to these tasks.ApplicationsProgrammable voltage sourceProgrammable current sinkHarsh environment operationProcess control

The ISO-DA8 CR is an ISA bus analogue output card for PC/AT compatible computers. It provides eight 14-bit channels with optical isolation rated for up to 2500 VDC common-mode voltage, so it suits programmable source and loop-driving tasks where field wiring must be kept apart from the PC.Each channel can be configured in software as a voltage output or a 4 ~ 20 mA current sink. Output type (unipolar or bipolar) and range, covering 0 ~ 5 V, ±5 V, 0 ~ 10 V and ±10 V, are set by software. The card uses a double-buffered D/A latch and a command set for programming, and its calibration is performed in software with data stored in EEPROM, so there are no jumpers or trimpots to adjust.The board also provides 16 digital inputs and 16 digital outputs at 5 V/TTL levels, plus three 16-bit timer/counter channels. A power-on value for each output can be predefined and held in the on-board EEPROM. A CA-4002 D-Sub connector is included, and the card draws 800 mA from +5 V with an operating range of 0 ~ +60°C.ApplicationsProgrammable voltage sourceProgrammable current sinkHarsh environment operationProcess control

The ISO-DA8/S CR is an isolated analog output card for PC/AT compatible computers, providing eight 14-bit channels that can drive voltage or current loads. Each channel has its own converter with built-in DC/DC isolation, which suits engineers who need to keep control outputs electrically separated from the host PC.Output type and range are set in software, so unipolar or bipolar operation and the 0 ~ 5 V, ±5 V, 0 ~ 10 V or ±10 V ranges can be changed without hardware adjustment. The board is jumperless and trimless, and calibration is performed in software with the data held in EEPROM. The power-on output value can also be defined and stored on board, which helps when outputs must start from a known state.The card also provides 16 digital inputs, 16 digital outputs and three 16-bit timer/counter channels, all at 5 V/TTL levels. This ordering code is supplied with a DN-37 Terminal Board and a CA-3710 D-Sub cable, rather than the CA-4002 D-Sub connector listed for the ISO-DA8 CR.ApplicationsProgrammable voltage sourceProgrammable current sinkHarsh environment operationProcess control
