Bistable/Latching DPDT 2A Power Relay Module
This is a compact Bistable/Latching Relay Module and can be used in various power functions and or applications which require a memory state.
This Module is pre assembled, tested and made from high quality FR4 board.
Terminals 1, 2 and 3 and the set/reset terminals. Terminal 3 common negative.
Terminals 4 and 6 provide the supply voltage which gives terminals 6 and 7 as output 1 (Set) and terminals 8 and 9 as output 2 (Reset).
When power to the module has been disconnected the module remembers its current state for when power is reapplied. The LED is lit when control voltage is applied and the module is ready for triggers set/reset. The control voltage is rated at 12v DC – 25v DC
Please note that PCB Pillars / Standoffs will be required for the circuit board. These fit into the 4 pre drilled holes of the circuit board. We have varies types available in our store
| Control power supply | 12v DC – 25v DC |
| Set/Reset | 10v DC - 20v DC |
| Output Voltage | 12v DC – 25v DC 2A (Depending on the Control power supply voltage) |
| DPDT Relay Module | 25v DC 2A (up to a 60W motor) |
| Board size | 48mm x 30mm x 16mm |

With over 15 years of experience in the electronics industry Modelling Electronics are a professional, family run business for the manufacture and supply of a range of electronic components, switches and electronic circuits dedicated to the hobbyist. Our electronic components and switches are aimed at hobbyists such as, model rail / model railroad, dolls houses and electronic enthusiasts.
All our circuits are made by humans rather than assembly lines so that we can help growth by employing staff within the UK. By buying from us your are helping employment levels within the UK.
If you are interested in electronics or developing your own printed circuit boards we offer a number of FREE tutorials and projects which you can read on our website and also download a pdf version. We also have created a common frequently asked questions section to help users. This covers things like an LED resitor calculator, all about diodes and capacitors plus much more.
If you require access to these FREE tutorials please feel free to contact us or visit our website.
Due to the sensitivity of these circuits and components, (due to damage incurred by incorrect wiring) we can only accept returns and issue a refund once our engineers have fully tested and confirmed the component or circuit is fully working. We test each circuit before it leaves our factory, which is then verified by a senior team member and signed off. Please make sure you read our website for product data sheets and wiring instructions before you connect your component or circuit.
