2-channel sequential delay timer relay module. Individual activation time setting from 1 to 180 seconds for each relay. 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 mod so it initiates on powering up. Instant-On mode is set using a header jumper not included (Order Code JUMPER-RED).
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. VM188). This setup provides automatic and continuous retriggering of the timing cycle 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 0.1 - 240 seconds. Scale switches select one of two delay ranges, 0.1 to 24 seconds or 1 second to 4 minutes, giving more precise and easier time setting using the onboard potentiometer (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.
The module has no memory function and will always start from the relay 1 position when first activated.
You can also use this board to reverse the direction of a DC motor or polarity of a DC supply voltage.
2023 Product Update: New improved DIN-Rail size board with wider time range and easier setting. NB Video shows the old version of this product but application is essentially the same.Specifications
