This is a downstream E-blocks peripheral module, designed to be controlled by one of the upstream E-blocks processing boards which are available in a variety of MCU/CPLD architectures.
The Quad Channel Opto-Isolated Input Board is designed to allow electrical isolation between circuits. Because the Opto-Isolator board uses light to transmit information, it can be used to protect circuits operating at lower voltages (e.g. microcontrollers) from circuits operating at higher voltages (e.g. motors).
It creates an interface between an upstream E-block and circuits operating at higher voltages. The on-board chip is a TLP620-4 opto-isolator.
- Provides the capacity to operate two circuits at different voltage levels.
- Provides the ability to isolate up to four circuits.
- Employs LEDs for instantaneous acknowledgment of board status.
- E-blocks compatible.
E-Blocks Overview E-Blocks are small circuit boards each of which contains a block of electronics that you would typically find in an electronic system. Each E-Block performs a separate function as either an input sub-system, an output sub-system, an input/output sub-system or a processing sub-system.
E-Blocks can be put together to form a variety of systems that can be used for teaching and learning electronics, and for the rapid prototyping of complex electronic systems.
Each E-Block has one or more 9-way D-type connectors that provide up to eight input/output lines and a ground line. These D-type connectors allow connection between E-Blocks to be made in buses of multiples of 8 lines, just like a real electronic system. Power is routed separately to those E-Blocks that need it.
Processing E-Blocks based on PIC, dsPIC, ARM or AVR microcontrollers control the whole E-Blocks system. Processing E-Blocks provide up to five input/output ports with up to eight lines per port.
Please see the E-Blocks Category for a list of available components. For more details on E-Blocks, see the E-Blocks User Guide (in English, French, German and Spanish) or watch the Introduction to E-Blocks video.
