Sensors

Proximity (Capacitive, Inductive), Photo electric (Thru beam, Retro Reflective, Diffuse), Ultrasonic, etc. Sensors can be either discrete (On/Off) or Analog outputs.

Arduino Uno Super Starter Kit Hardware

by

Arduino consists of a family of single programmable circuit boards and the IDE (Integrated Development Environment) that uses a streamlined version of C++ to write and upload code to the boards. Many pre-configured circuit boards, called “shields”, are available to expand the functionality of the Arduino controller. These shields can provide Ethernet, WiFi, GPS, LCD … Read more

P1AM Industrial Arduino P1000 Expansion Analog

by

We will now look at the P1AM Arduino expansion analog modules. This analog expansion is part of the P1000 cards that the P1AM Arduino can use as it’s inputs and outputs. The productivity open P1AM I/O interface chip-set supports the full suite of Productivity 1000 I/O expansion modules. These modules are industry approved and proven … Read more

Capacitive Pushbutton Sensor Switch /Indicator

by

We will now look at the capacitive pushbutton sensor switch and indicator. Normal pushbuttons on a panel are usually a mechanical device. They can become “sticky” when too much dirt or oil is present. Capacitive push buttons do not have moving parts to stick, so the life expectancy is increased. Disinfectant sprays can be applied … Read more

Productivity 1000 PLC to Modbus TCP RTU BX-MBIO

by

We will now look at the productivity 1000 plc modbus tcp rtu communication to the BX-MBIO controller. The Productivity 1000 PLC can communicate to a remote I/O (input and output) controller modules using the Modbus protocol for communications. The BX-MBIO provides both Modbus RTU and Modbus TCP interfaces. Modbus RTU is a serial communication and … Read more

P1AM Industrial Arduino GPIO Inputs and Outputs

by

The P1AM-GPIO is an industrial rated shield for the P1AM-100 Arduino system. It provides a connection from most of the P1AM-100 GPIO pins to the front 18 position terminal block connector. We will be looking at the wiring and programming of this input and output industrial rated shield that mounts on the left side of … Read more

Wiring 3 Wire DC NPN and PNP Sensors

by

Wiring 3 wire DC sensors can be confusing. I recently received a question on PNP and NPN sensors. They wanted an explanation of what a sink is and how to wire one. Confusion over the Normally Open and Normally Closed function of the sensor is also a common question. Several diagrams will show a resistor … Read more
