I have a piece of hardware that needs to be controlled with software, some screen scraping and about 5 to 10 commands need to be executed. I am flexible with language and platform but ideally I would like it to run on Linux for stability purposes. I would if possible like it client / server type set up but that can be developed later. I have done initial research and have determined the connection...
...assemble and program a relaycontrol from a dry contact input.
It needs toggle a relay when two triggers...INPUT = SINGLE N/O DRY CONTACT
OUTPUT = SINGLE RELAY ANYTHING LESS THAN 1 AMP
I would like a price
ThWe are a group of Turkey named Ar-Ge Turk www.Ar-GeTurk.com.tr. We need a simple programm of Android which is some buttons, That buttons is controlling relays and We will get feedback. This project is like that: http://www.dailymotion.com/video/x160b98_dc-and-ac-power-output-smartphone-wifi-controller-controls-ac-lamp-android-system_tech.

Digital input/output/RS485/relay output PCB for Raspberry pi
...inputs must be triggered with negative signals
3) RS485 to 3.3v UART chip 485 side broken out to screw terminal...needs to be powered from the 12v supply.
6) all relay contacts needs to be broken out to screw terminals
Two arduino Mega shall communicate over RS485 and have a 50-200 meter of cat5 cable between them...will have several switches and potentiometers to control relays on Arduino #2 and have a display that will
...a surface control box and one in subsurface control box. One Arduino Nano card to control the Video overlay...card.
The two Mega cards will be connected with RS485 (Max485 chip) and 50-150 meter long cat 5 cable...card over normal serial. Can also be connected to RS485 if required.
3 different codes must be supplied
Talk to a Serial attached thermostat using the attached protocol doc.
This should be controlled by a web page with the following features...
> Web page in IIS
> Windows Com port to use should be selectable
> Apps will display current information from device when loaded
> App will allow setting of available options
App must support Windows server 2008 and above 32bit and x64...
This project is base on this relay board, refer to http://denkovi.com/product/46/ethernet-ip-control...telnet.html.
1. to attach a key pad to the relay board and some programming need to be done here...for door access control.
2. to create website to monitor the status of all in/out relay and time in/out
...need to be programmable ) and turn on and off a relay a number of times corresponding to the digits displayed...digits are represented by the number of times a relay is switched on and off. There are some secifc timings
...baud rate RS485 / CAN (Driver only, not the protocol!). #2 communicates with #3 also via RS485 or CAN transceivers...where it is decoded. During "unused frames on the 2 RS485 / CAN links, only frames are sent with the Pulse...the twisted pair using RS485 or CAN transceivers. If errors occur, the RS485 / CAN speed is reduced.
...to write a piece of software that will control a common USB relay. (details attached)
Its a common...common chinese manufactured USB Relay made by www.lctech-inc.com
We need a very simple and robust application...have an ON and OFF option which will trigger the relay and change the image showing on the icon.
...provide a device (circuit) that can monitor and control the power from an AC mains socket using an Arduino...devices from the mains supply.
Switching of the Ac relay should be done via bit changing of one of the arudino's...Arduino to provide monitoring data, power and relaycontrol.
The preference is to use an IC, such as
...enclosure with the sensor which communicates via RS485. Power supply will be 12-24VDC. Data will be received...to the server. The logger will also require 2 relay(1A,240VAC)outputs and 2 isolated inputs. Commands...12-24VDC. This unit will also be required to control up to 4 sensor units. Local LCD display of sensor
Project is split into two PCB’s
PCB 1 – (relay circuit)
• 230 volt AC input to screw terminals on PCB
• Relay switching controlled by wireless circuit
• Relay capable of 230v AC and 10amps
• Relay with...open and normally closed
PCB 2 – (wireless control circuit)
• 230 volt AC input to screw terminals
