The VELLEMAN VM142 Mini PIC-PLC Application Module Kit is a flexible programmable controller platform designed for custom automation, monitoring, and embedded control applications. Built around the reliable Microchip PIC16F630 microcontroller, this compact development module allows hobbyists, students, and engineers to create their own programmable control systems without the need to design complex interface hardware.
The VM142 combines the functionality of a small PLC (Programmable Logic Controller) with the flexibility of a programmable PIC microcontroller, making it suitable for industrial control, home automation, robotics, automotive electronics, security systems, educational projects, and countless custom embedded applications.
At the heart of the module is the PIC16F630 microcontroller, operating from its fixed 4MHz internal oscillator, providing a stable platform for user-developed firmware. Programming is performed via the integrated ICSP (In-Circuit Serial Programming) connector, allowing the microcontroller to be programmed without removing it from the board using compatible PIC programmers.
The module provides nine programmable input/output lines, consisting of four voltage-sensing inputs and five programmable outputs, giving developers extensive flexibility when designing custom control systems.
The four inputs accept external control signals between 5VDC and 24VDC, making the VM142 compatible with switches, sensors, industrial control signals, and many other input devices.
For output control, the module includes four NPN open-collector transistor outputs, each capable of sinking up to 100mA, allowing direct control of LEDs, relays, indicators, buzzers, and other low-power loads. These outputs are also capable of directly driving 12V relay coils without requiring additional protection diodes.
An additional on-board relay with Normally Open (NO) and Normally Closed (NC) contacts provides isolated switching of external equipment up to 2A, making the module suitable for controlling motors, lighting, pumps, alarms, solenoids, and automation systems.
To simplify application development, the VM142 includes several integrated indicators, including a power LED, relay status LED, a user-programmable LED, and an on-board miniature buzzer for audible status indication, alarms, or feedback generated directly by the application software.
Powered from an unregulated 12VDC supply, the module is easy to integrate into control cabinets, automation systems, educational laboratories, and prototype electronics projects.
Whether developing custom industrial controllers, smart home devices, robotic systems, automotive electronics, or learning embedded programming, the VELLEMAN VM142 Mini PIC-PLC Application Module Kit provides a powerful and versatile hardware platform for virtually unlimited programmable applications.
