RPC628 High Speed Analog and Digital I/O Card for PC/104
Extremely versatile card has 16 Analog Inputs, 8 Analog Outputs, 16 Digital I/O and many programmable modes
Springville, Utah - The RPC628 from Robotrol Corporation contains 16 analog-to-digital inputs, 8 digital-to-analog outputs, and 16 digital I/O with many versatile programmable modes.
The analog inputs have 12 bit resolution and may operate as 16 single-ended inputs or 8 differential inputs with each input protected to +-32 volts. Full scale voltages (unipolar or bipolar) from 25 millivolts to 10 volts may be used. A/D conversions may be controlled in the following ways: random channel single conversions per command, a single conversion per command with auto increment, continuous conversions in a single channel, continuous conversions with auto increment or by external trigger. Conversion intervals may be programmed from 4 microseconds to 64 milliseconds. Four to 20 ma current loops are available as an option.
The 8 analog outputs have 12 bit resolution and may be set to one of seven voltage ranges: 2.5V, 5V, 10V, +-5V, +-10V, -5 to 0V, -10 to 0V. Four to 20 ma current loops are available as an option. When a card has current loops installed, analog outputs can be configured as all current loops, all voltages or a mixture of the two.
The 16 digital I/O can be individually programmed to be either inputs or outputs. After a power-on-reset or software reset all I/O are configured as inputs. I/O may be configured as outputs by writing "ones" to the corresponding bits in the Digital I/O Direction Register.
The RPC628 has the following programmable features: data transfer width (8 or 16 bits), interrupt enable, auto increment enable, continuous conversion enable, maximum channel number for auto increment, conversion interval (4 microseconds to 64 milliseconds), two's complement or straight binary A/D data, maximum D/A channel number, digital I/O direction, and software reset.
FEATURE SUMMARY:
o 16 SE or 8 DI Analog Inputs, Ranges: 25mv to 10V (unipolar or bipolar)
o 8 Analog Outputs, Ranges: 2.5V, 5V, 10V, +-5V, +-10V, -5 to 0V, -10 to 0V
o 250 kHz A/D Throughput Rate, Inputs protected to +-32V
o 16 Digital I/O Bit by Bit Programmable as Inputs or Outputs
o Options: 4 to 20 ma current loops for both Analog Inputs or Analog Outputs, Extended Temperature Range
o Auto Increment and Continuous Conversion Modes
o Programmable Conversion Intervals from 4 Microseconds to 64 Milliseconds
o Interrupt, Polled Status, and External Trigger Capabilities
