Description
Technical Specification

AD Analog Input function

◆ converter type: ADS774JP

◆Input Range: ± 10V, ± 5V, 0 ~ 10V

◆ Conversion Accuracy: 12 (Bit)

◆ Sample Rate: the highest rate of 100KHz

◆ sampling channel: software-selectable, by setting the first channel to achieve the end (Last Channel – First Channel + 1)

◆ physical channel: 16 channels (single-port SE), 8 channel (double-port DI)

◆ channel switching mode: the first and the end channel switching in proper order (software trigger switch, only the issue of reading the data when they switch the order)

◆ Analog Input mode: single-ended analog input and dual-ended analog input (also known as two-terminal differential input) ◆ amplifier type: INA128P

◆ amplifier gain G and the resistance of computing RG1 relationship: G = 1 + 50KΩ / RG1 Notes: amplifier gain and resistor RG1 correspondence as shown in table 1.

◆ Analog input impedance: > 100MΩ

◆ System measurement accuracy: 0.1%

DA analog output function ◆ Converter: DAC7625 ◆ output range: 0 ~ 5V, 0 ~ 10V, ± 5V, ± 10V ◆ Conversion Accuracy: 12 ◆ output rate: 100KHz (10us / points) ◆ set-up time: 10μS (0.012% accuracy) ◆ Number of output channels: 4-way ◆ Non-linear error: ± 2LIB (maximum) ◆ output error (full range): ± 1L DI Digital Input Function ◆ latch: 74LS245 ◆ Number of channels: 8 ◆ Electrical standards: TTL compatible ◆ maximum absorption current: less than 0.5 milli-amperes ◆ high minimum voltage: 2V ◆ low maximum voltage: 0.8V DO Digital output function ◆ drive: 74ALS273 ◆ Number of channels: 8 ◆ Electrical standards: TTL compatible ◆ the largest pull-pull-down current: the pull-down current of 20mA, pull current 2.6 mA ◆ high minimum voltage: 3.4V ◆ low maximum voltage: 0.5V Timer / counter 8254 ◆ counter channel number: the three independent subtraction counter ◆ counter median: 16Bit ◆ operation type (Operate Type): four types of software to operate the optional ◆ counting methods (Count-Mode): count the way the six software selectable ◆ Count-Type: binary code BCD counting and counting ◆ input electrical standards (CLKn, GATEn): the highest voltage for low 0.8V, the minimum high voltage of 2.2V ◆ output electrical standards (OUTn): the highest voltage for low 0.4V, the minimum high voltage of 3.0V
