Functional Description
The ETH-IDIO-16 Series (4, 8 and 16 channels) is an ideal solution for adding portable, easy-to-install,
isolated input and solid state output digital I/O capabilities to any Ethernet network. It is excellent for
controlling external relays, driving indicator lights, fuel pumps, high voltage control and more. Typical
industries are Automotive, Industrial, and Factory and Home automation.
This unit features 16 high-side MOSFET switch outputs and 16 optically isolated digital inputs. The isolated,
non-polarized inputs may be driven by either DC sources of 3-31 V (or higher by special order) or AC
sources at frequencies of 40 Hz to 10KHZ. Optically isolating the digital inputs from each other, and from the
computer and network, assures smooth, error-free data transmission in noisy, real-world environments.
The input channels are accessed via a 34-pin IDC type vertical header. The fully protected isolated outputs
are de-energized at power-up to prevent an unintended control output signal. Data to the solid state outputs
are latched and are available via a 50-pin IDC type vertical header. To simplify field wiring connections, the
ETH-IDIO-16 family includes an internal, removable termination board (ETH-STB-84), that mounts directly to
the headers.
