As PICmicro microcontroller circuitry will not drive high power AC loads, some form of switch or ‘relay’ is required to
perform the task. The EB038-00-1 Quad Relay 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 the user to switch multiple devices (ie,
motors) simultaneously.
Relay rating
The EB038-00-1 Quad relay board 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. Fig 1.0 illustrates a layout
diagram of the relay.

C – Common.
NO – Normally Open.
NC – Normally Closed.
LEDs are employed within the circuit to register the switching status of the relay (ie, when relays switch to Normally
Open, LEDs illuminate). VPWR must be greater than 12V.
A set of jumper links is available for the Quad relay board. Jumper links provide the user with the ability to control the
relays with the HIGH nibble or LOW nibble.
NB. VPWR cannot be 3.3V or 5V. VPWR must be greater than 12V. VPWR can be supplied by +14V on the EB006
board.
Provides the capacity to operate two circuits at different voltage levels.
Provides the ability to operate up to four devices (ie, motors) at varying speeds.
Employs LEDs for instantaneous acknowledgment of relay setting.
E-blocks compatible.
