2-channel sequential delay timer relay module with independently settable delay periods from 2 to 45 minutes. Communication I/O connections to daisy chain multiple units. Mains rated relay outputs. Start and Reset switch inputs. Instant-on option.
The module can be activated by the Start Input (using for example a push button or relay contact closure) or by selecting the Instant-On option so it initiates on powering up.
On activation Relay 1 turns on for a user-adjustable delay period. On completion, Relay 1 turns off and Relay 2 turns on for a second user-adjustable delay period. When relay 2 turns off the unit returns to its standby state. A fresh Start Switch input is required to repeat the cycle. This can be performed manually or automatically if you connect the Start Switch input to the relay output of a cyclical timer (e.g. CI010/11/12 or CI110/11/12, 3141 or 1180). This setup provides automatical and continuous retriggering of the CI028 with a user adjustable pause time provided by the cyclical timer to produce a repeating on/off/pause/on/off/pause/etc. effect.
Both delay periods are independently settable from 2 to 45 minutes using the onboard potentiometers (header pins allow the use of user-supplied external potentiometers if required).
A Reset Switch input immediately stops the timing sequence, turns off the active relay and returns the module to its standby state.
Each board has a communication input and output that allows several boards to be daisy chained together in series.
The module has no memory function and will always start from the relay 1 position when first activated.
You can also use this board for reversing a DC motor.
