PC/104 16-Channel 12-bit ADC Inputs, 16 Digital I/Os, and 3 Timers
|
Analog-to-Digital Conversion
The analog-to-digital (A/D) circuitry receives up to 16 single-ended analog inputs and converts these inputs into 12-bit digital data words which can then be read and/or transferred to PC memory. The analog input voltage range is jumper-selectable for bipolar ranges of -5..+5 V or -10..+10 V, or a unipolar range of 0..+10 V. The module is factory set for -5..+5 V. Overvoltage protection to ±35 volts is provided at the inputs. A/D conversions are performed by a 12-bit successive approximation converter. This high-performance converter and the high-speed sample-and-hold amplifier preceding it make sure that dynamic input voltages are accurately digitized. The resolution of a 12-bit conversion is 2.4414 mV on the -5..+5 V range and the maximum throughput is 40,000 samples per second. The converted data is read and/or transferred to PC memory, one byte at a time, through the PC data bus.
8254 Timer/Counter
An 8254 programmable interval timer contains three 16-bit, 8-MHz timer/counters to support a wide range of timing and counting functions. The clock, gate and output pins for each of the three timer/counters are available at the I/O connector.
Digital I/O
The DM6210 has 16 TTL/CMOS-compatible digital I/O lines which can be directly interfaced with external devices or signals to sense switch closures, trigger digital events, or activate solid-state relays. The lines can be programmed as inputs or outputs in groups of 4 bits. There is also a special latched input mode which allows the digital inputs to be latched on an external clock edge for time critical applications. Pads for installing and activating pull-up or pull-down resistors are included on the module.
