Look for ambitious person to design and build a basic one-shot monostable trigger. Device input voltage from 12-24vdc device needs to have 12-24vdc positive trigger capabilities Output must be able to drive a 30 amp load. Trigger must incorporate variable trigger length durations from .001 to 5 seconds. Device must function as jog once upon trigger no matter how long trigger is closed Device sophistication can employ power on led and LCD cycle setting selection
The One-Shot-Trigger is the essential component which allows Monostable PWM to be output to a solid state relay to actuate a motor
There are up to 8 One-Shot-Trigger operations required on the board which can be enabled or disabled to allow user to jog as long as switch is held operation
Each trigger being programmed as enabled; set time; or disabled
Board LCD should have status readout of programmed function
He board has one channel for emergency Stop function which is latch on and latch off
Channels all channels need to be integrated into a 24V 433MHz wireless RF Remote Control Switch Receiver paired with its unique Transmitter or BlueTooth app
Also if graphic display is used a simulated automobile silhouette could be calibrated to show user the current position of the vehicle; i.e. back up/ front down; back down/ front up. Selectable at startup stored and retained for recall by resetting zero origin points and by setting one shot PWM upper limit extreme set points to calibrate Silhouette. Data can be sent to app for 3d depiction
Firmware should display boot function of company logo and periodically flash company status information. Thank you for choosing …………………..
Board incorporates single Channel for a All STOP emergency function output to SSR
The board should have a memory program and play back sequence.
Whereby the board can be set to remember mode. And during remember mode the board will monitor user input and store it for later playback upon selection.
Firmware will have set time to start playback task (1min.) or user should be able to self start by pressing key combination of some sort. With flashing LED on remote to declare program playback mode
In user playback mode every start function is down channel 2, 4, 6 as user has defined in setup mode; this is so that during playback mode the positions start from an origin of zero to prevent failure due to misalignment of actual and programming positions.
These functions can be used for Android or Iphone App which could be in addition to the remote but will require BlueTooth technology
The remote must be able to latch the channel to a particular button on the transmitter
The Last channel is and emergency stop (latching-on); (latch-off)
In case of user desire to exit program playback stop option could be used by sending long pulse by pressing any key to reset. Or using emergency stop
