Features
Rich set of basic functions Compact system providing high-precision bus isolation analog I/O. This product is a control signal(Isolation TTL level 6 points) of analog input(16bits, 8ch), analog output(16bits, 2ch), analog I/O. Digital inputs (Isolation TTL level four points), digital outputs (Isolation TTL level four points), and a counter (32-bit, Isolation TTL level one point) common to the three models. Bus isolation between PC and external I/O signals by a digital isolator Isolation between PC and external I/O circuit by a digital isolator improves noise tolerance. Substantial control functions Capable of analog input/output in either time-based mode or external- signal synchronous mode. Filter function facilitating external signal connection Digital filters provided for external control analog I/O signals, preventing chattering Buffer memory The analog inputs and outputs each have their own buffer memory. You can also perform analog input and output in the background, independent of software and the current status of the PC. Software-based calibration function Calibration of analog input/output can be all performed by software. Apart from the adjustment information prepared before shipment, additional adjustment information can be stored according to the use environment.

The numbers correspond to channel numbers. Analog Output00 - Analog Output01 Analog output signal. The numbers correspond to channel numbers. Analog Ground Common analog ground for analog I/O signals. AI External Start Trigger Input External trigger input for starting analog input sampling. AI External Stop Trigger Input External trigger input for stopping analog input sampling. AI External Sampling Clock Input External sampling clock input for analog input.

Counter Gate Control Input Gate control input signal for counter. Counter Up Clock Input Count-up clock input signal for counter. Counter Output Counter output signal. Digital Ground Common digital ground for digital I/O signals, external trigger inputs, external sampling clock inputs, and counter I/O signals. Reserved Reserved pin. N.C. No connection to this pin. CAUTION - Do not connect any of the outputs and power outputs to the analog or digital ground. Neither connect outputs to each other. Doing either can result in a fault. - If analog and digital ground are shorted together, noise on the digital signals may affect the analog signals. Accordingly, analog and digital ground should be separated. - Leave "Reserved" pins unconnected. Connecting these pins may cause a fault in the board. Analog Input Signal Connection Single-ended Input The following figure shows an example of flat cable connection. Connect separate signal and ground wires for each analog input channel on CN1. Single-ended Input Connection (Flat Cable) The following figure shows an example of shield cable connection. Use shielded cable if the distance between the signal source and board is long or if you want to provide better protection from noise. For each analog input channel on CN1, connect the core wire to the signal line and connect the shielding to ground. Single-ended Input Connection (Shield Cable) *1 The number of channels depends on each board. The ADAI16-8/2(LPCI)L has eight channels. CAUTION - If the signal source contains over 1MHz signals, the signal may effect the cross-talk noise between channels. - If the board and the signal source receive noise or the distance between the board and the signal source is too long, data may not be input properly. - An input analog signal should not exceed the maximum input voltage (relate to the board analog ground). If it exceeds the maximum voltage, the board may be damaged. - Connect all the unused analog input channels to analog ground. - The signal connected to an input pin may fluctuate after switching of the multiplexer. If this occurs, shorten the cable between the signal source and the analog input pin or insert a high- speed amplifier as a buffer between the two to reduce the fluctuation. - An input pin may fail to obtain input data normally when the signal source connected to the pin has high impedance. If this is the case, change the signal source to one with lower output impedance or insert a high-speed amplifier buffer between the signal source and the analog input pin to reduce the effect. - Analog ground of CN1 is isolated from the ground in the PC. Analog Output Signal Connection This section shows how to connect the analog output signal by using a flat cable or a shielded cable. The following figure shows an example of flat cable connection. Connect the signal source and ground to the CN1 analog output. Analog Output Connection (Flat Cable) The following figure shows an example of shield cable connection. Use shielded cable if the distance between the signal source and board is long or if you want to provide better protection from noise. For each analog input channel on CN1, connect the core wire to the signal line and connect the shielding to ground. Analog Output Connection (Shield Cable) *2 The number of channels depends on each board. The ADAI16-8/2(LPCI)L has two channels. CAUTION - If the board or the connected wire receives noise, or the distance between the board and the target is long, data may not be outputted properly. - Do not short the analog output signal to analog ground, digital ground, and/or power line. Doing so may damage the board. - Do not connect an analog output signal to any other analog output, either on the board or on an external device, as this may cause a fault on the board. - Analog ground of CN1 is isolated from the ground in the PC. Digital I/O signals, Counter signals and Control signals Connection The following sections show examples of how to connect digital I/O signals, counter I/O signals, and other control I/O signals (external trigger input signals, sampling clock input signals, etc.). All the digital I/O signals and control signals are TTL level signals. Digital Input Connection Digital Output Connection About the counter input control signal Counter Gate Control Input acts as an input that validate or invalidate the input of an external clock for the counter. This function enables the control of an external clock input for the counter. The external N.C. AGND N.C. AGND AI 04 N.C. AI 05 N.C. AGND AGND AI 06 N.C. AI 07 N.C.

Ver.1.02 AIO-160802LI-PE 4 clock for the counter is effective when input is "High", and invalid when input is "Low". If unconnected, it is a pull-up in the board (card) and remains "High". Therefore the external clock for the counter is effective when the counter gate control input is not connected. CAUTION - Do not short the output signals to analog ground, digital ground, and/or power line. Doing so may damage the board. - Do not connect a digital output signal to any other digital output, either on the board or on an external device, as this may cause a fault on the board. - Analog ground of CN1 is isolated from the ground in the PC.
