Overview

The Model 104-IDIO-16 is a 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 sourcing 2A 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 boards typical response time to 10 µsec 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. Model 104-IDIO-16E is an economy version available without the interrupt Change of State Detection feature. The 104-IDIO-16 is designed for use in both commercial and optionally in industrial environments of 0 to +70°C and -40 to +85°C, respectively. Models 104-IDIO-8 and 104-IDIO-8E feature 8 optically isolated inputs and 8 optically isolated solid state outputs. Also available is Model 104-IDO-16 which has 16 outputs only, Model 104-II-16 which has 16 input only, and 104-IDO-8 which is the 8 outputs only version.
