Click PLC Analog Dusk to Dawn Program Example

A dusk to dawn sensor usually is discrete on/off of the lighting control. If we want to vary the lights to mimic more of the sunset and rise, we would use an analog output to control the lights. I was recently asked about such a program. Every day they wanted the lights to go off at 10 pm and come back on at 6 am. At 9:30 pm the lights would be on at 70% or 7volts of a 0-10V signal. In the next half hour, the program will bring the lights from 70% down to 0%. In the morning the lights will come back on within the half-hour from 0% to 70%. Poultry Farms are one place that would utilize this program. We will be developing a program that will do this with our Click PLC. Let’s get started! More information can be obtained on our website.

Here are just a few. - Investment is low for the hardware and the software is free - Standalone PLC with built-in I/O - Communication ability - Ethernet Port, RS232, RS485 - support for protocols such as Modbus RTU, Modbus TCP, etc. - Ability to expand the system with a variety of modules including RTD and Thermocouple inputs directly. https://www.accautomation.ca
