  • Four channels of optical isolation with open-drain outputs
  • Non-inverting output and inverting output for each channel
  • LEDs provide visual indication for each signal and power
  • Wide operating voltage range (3.3V to 24V)
  • Suitable for signals from 3.3V logic up to 24V logic
  • Buffered output stage for higher current sink capability
  • Includes reverse-polarity protection on inputs and outputs
  • Redundant power and ground terminal-block connections
  • Mounting Options: Rubber Feet, Panel, or DIN Rail


General Description

This product provides four channels of optical isolation with both a non-inverting output and an inverting output for each channel. Both the input side and the output side are designed to interface with equipment using logic voltages of anywhere from 3.3V to 24V. This robust design includes low-side output drivers that provide significant sink current capability. Reverse-polarity protection on inputs and outputs is also included.

This board includes terminal blocks to provide convenient access to the signals.

An opto-isolator is sometimes referred to as a "photocoupler", "optical coupler", "optocoupler", "opto coupler", or "optical isolator".

Applications

  • Electrical Isolation
  • Interface between equipment with different grounds
  • Interface between equipment with different logic levels
  • Low-side driver for small DC loads (motors, solenoids, bulbs, etc)

OPI104-x Variants

The original OPI104 variant (OPI104-DIN, OPI104-FT) utilizes an output stage which includes current limit and thermal limit features, but whose output switching speeds are slower due to the protection circuitry. Due to present supply chain delays for the protected output stage components, we have introduced a new variant which uses a standard output stage, and whose switching speeds are much faster. The new part numbers are OPI104-HS-DIN and OPI104-HS-FT.

  • OPI104: outputs feature protected N-FETs with built-in current limit and thermal limit
  • OPI104-HS: outputs feature standard N-FETs with lower resistance and faster switching

Mounting Options

These products are available in two different mounting variants. Product numbers ending with -DIN come with DIN clips already installed and ready to snap onto 35mm or 32mm DIN rail. Product numbers ending with -FT have stick-on rubber feet installed on the bottom side, allowing for benchtop use or panel mounting. For panel mounting, we suggest 1/4" nylon standoffs under the mounting holes, and #6 screws.
