New from Bigelow Brook Farm!

The IX Series Sequencing Timers let you run your aquaponic or hydroponic system exactly as you need it to run!


The IX-180 also accepts an optional temperature probe!

Some examples of how a sequencing timer can be used:

  • Sequencing Mode (all models): Only one pump is on at a time. The perfect option would be to have 2 pumps in a sump, each filling their own bed one at a time.
  • Sequencing Mode (all models): Have one pump always running, the timer is connected to 2 solenoid valves which then fill their own grow beds. With the future optional IX-180 expansion module, this converts the IX-180 timer into a 4 relay system.
  • Timer Mode (all models): The 2 relays work independently of each other as though you purchased 2 individual low-end timers. The on/off times for each relay can also be configured to their own times.
    • You could run 2 separate system pumps with this – each pump in its own sump.
    • You could have a system with one pump, then run grow lights from the second relay. (note that this doesn’t have a clock so you can’t tell it to turn the lights on at 6:00am. They would turn on whenever you turn on the timer, but you can force the sequence to toggle the lights on or off at around the correct times. Also note that the entire relay board is fused for 8 amps so some of the bigger HID lighting systems wouldn’t work.)
  • Timer Mode & Temperature Sensor: (IX-180 only) Run the pump or lights on one relay and connect the temperature sensor for the other. This would be great in a greenhouse where you may want to connect it to a fan for cooling. The unit also has an alarm buzzer so if the temp goes above or below a set point, it will make a horrific noise!
  • Just Temperature Sensor: (IX-180 only) You can also have the relays just work on temperatures.
    • One sensor can run both relays, where each relay has their own set point. For example, if it goes above 75 degrees in your greenhouse have it turn on a fan. If that fan can keep up and the temperature goes above 80, turn on a second fan. To get even fancier, if the temp goes above 85, have the alarm buzzer sound!
    • Connect 2 temp sensors. This could come in handy for a larger structure where you sort of want to break the greenhouse into 2 cooling zones. Each sensor could run its own fan in 2 different areas.
  • More complex: (IX-180 only) The inputs can also read a digital signal. For example, you could build a float switch for their grow bed. Turn on the pump to fill the bed that has a simple standpipe with a small weep hole in the bottom of it. Then set it up the fill the bed, when the float switch triggered, it could turn off the pump for an hour or 2 and the bed would slowly drain.
