The E-Block Quad Channel Relay Output Board was designed to switch four relays on and off as a direct response to the low voltage input of an EB006 Multiprogrammer Board. This in turn allows you to switch multiple devices (e.g. motors) simultaneously.

It creates an interface between an upstream E-block and apparatus operating at a higher voltage. Each of the PCB-mounted relays is rated at 12V/6A and contains a 400Ω coil.

E-Block Quad Channel Relay Output Board Features

• Provides the capacity to operate two circuits at different voltage levels.
• Provides the ability to operate up to four devices (e.g. motors) at varying speeds.
• Employs LEDs for instantaneous acknowledgment of relay setting.
• 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 8 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 control the whole E-blocks system. PICmicro microcontrollers are used as the preferred processor; they provide up to 5 E-block ports with up to 8 lines per port.
