SPECIFICATIONS & FEATURES The VM142 is equipped with a popular 8-bit Microchip® microcontroller. The PCB layout is designed in such way to include 4 buffered inputs and outputs, a potential-free relay output and an onboard buzzer. The PIC™ microcontroller is freely programmable and the software can be developed in Assembler,C o ...

DESCRIPTIONS OF THE TERMINAL BLOCK GND-Vin: Connect the power supply between connections GND and Vin. Apply a direct voltage of 12V (regulated or not regulated) between the two pins. The electronics of the module are protected against polarity inversion. The 12V DC must be connected to the “Vin” terminal, your ground ...

Out1,Out2,Out3,Out4: These are the four open-collector type outputs and can each handle a current of max. 100mA. These transistors are grouped in a transistor array chip, IC2. In case of damage of one of the four inputs or outputs, this IC type ULN2803A can be replaced easily and without soldering. I/O of the PIC16F630: P ...

BUZZER: The built-in buzzer with fixed frequency can be activated and deactivated in your program. Programming example: BSF PORTC,BUZZER ;activate the buzzer BCF PORTC,BUZZER ;deactivate the buzzer Diagnose LED (LD3): This LED is fixed connected to an I/O of the PIC controller and can be freely programmed. The built-in LE ...
