104-IDIO-16 & 104-IDIO-8
FEATURES
- 16 or 8 optically-isolated, non-polarized CMOS compatible digital inputs accept ±31VDC or AC rms
- IRQ on input change of state (COS) eliminates the need for constant polling
- Slow/fast filter to accommodate AC voltages and noisy DC inputs
- 16 or 8 optically-isolated fully protected high-current solid state outputs
FUNCTIONAL DESCRIPTION
The 104-IDIO-16 is a low cost 32-channel PC/104 utility board featuring 16 optically isolated inputs and 16 optically isolated solid state outputs. The isolated, non-polarized inputs may be driven by either DC sources of 3-31V (or higher by special order) or AC sources at frequencies of 40Hz to 10KHz. Optically isolating the digital inputs from each other and from the computer assures smooth, error-free data transmission in noisy, real-world environments. The 16 input channels are available via a 34-pin IDC type header. The fully protected solid state outputs,
capable of driving 1A each, are inherently
more reliable than electromechanical relays and give system architects a more robust product to design with. The solid state outputs are available via a 50 pin IDC type header.
Each input circuit includes a jumper selectable slow/fast filter to accommodate AC inputs and is also useful for slow DC inputs in noisy environments. The filter may be manually
disabled to increase the board’s typical response time to 10µs when used with faster DC inputs. The input impedance is 1.8K Ohms to accommodate a wide input range.
The board is installed by jumper selecting
base addresses and IRQ. System interrupts
are software controlled, enabling the board to generate an interrupt whenever one or more of the isolated digital inputs changes state. This eliminates the need for constant polling and greatly frees up system resources. Models 104-IDIO-16E and -8E are economy versions available without the interrupt Change of State Detection feature. Models 104-IDO-16 and -8 feature 16 or 8 isolated digital outputs only.
