INTRODUCTION
myPCLab is a very compact Data Acquisition tool that connects to a PC via a USB port and monitors two universal input
analog variables along with one digital input. From hobbyists to scientists, from simple technical tasks to complex
engineering activities, myPCLab can be an invaluable tool for on-line monitoring and data logging in school, laboratory
research, machine data recording and industrial understanding.
It comes with intuitive and easy-to-use Windows software which plots and records data, shows gauges, bargraphs and
digital readouts. The USB port is accessed as a virtual serial port, which makes myPCLab compatible with SCADA
software with Modbus RTU driver or with any program with ASCII serial communication.
Multiple units of myPCLab can be connected to the same computer, easily expanding the number of inputs. The
myPCLab software can simultaneously communicate with multiple modules.
This manual describes software installation and connection of input signals to a myPCLab module. Instructions on using
the software are available on its help system.
READ THIS RECOMENDATION TO AVOID DAMAGE TO YOUR COMPUTER.
myPCLab inputs are not electrically isolated from the USB port. Before connecting signals from sensors or
transducers, make sure that they are not in contact with any source of electrical power (wires or conductive
surfaces which may get energized). Input channels are not isolated from each other.

myPCLab module sensors and signals
Digital Input: Logic voltage or dry contact signals.
“0” Logic Level: contact closed or voltage lower than 0,5 Vdc.
“1” Logic Level: contact opened or voltage from 2,0 V to 5,0 Vdc.
Digital input special features: Digital input can be configured for counting, timing or frequency measuring (pulses per
time unit). Configurable: debounce time and scale factor.
Counting: It counts from 0 up to 4294967295. It is selectable to count on input rising edge, falling edge or
both. Maximum input frequency: 1 kHz (square wave, no debounce).
