Highly flexible 2 channel programmable sequential relay controller module. Ideal for creating complex multistep bespoke linear control sequences.
It offers the following features:
Each channel has an EXTernal Input for connection to a contact closure (e.g. push/slide switch, relay, etc). When the program reaches an EXT command instruction, it will read the status of the corresponding input and Activate the relay if the contacts are closed or Deactivate it if the contacts are open. Relay will change state if input state changes while an EXT command is activate.
Lets say you set the STEP time to 1 second and you want Relay 1 to activate 3 seconds after the sequence commences and turn off 5 seconds later. Program the 1st command instruction to turn Relay 1 Off for STEPs 1 to 3. Program 2nd command instruction to turn Relay 1 On for Steps 4 to 8. You can keep adding more On, Off or Ext commands to use up all 240 STEPs or use an END or END REPEAT statement to complete the sequence when required. You can do the same for both so complex multi-channel sequences are possible.
Programmes are entered, modified or deleted using the LCD display and push buttons on the display board. The same buttons are also used to Start and End the sequenced once programmed.
