Bistable/Latching 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 5 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 PCB Pillars / Standoffs
| 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 |
