Latching Outputs; Solid State Relays - Arduino AKX00034 Product Reference Manual

3.7 Latching Outputs

Connectors J9 and J10 provide outputs to latching devices like motorized valves. The latching output consists of
dual channels (P and N) through which an impulse or strobe can be sent in either of the 2 channels (to open a close
valve for example). The duration of the strobes can be configured to adjust to the external device requirement.
The board provides a total of 16 latching ports divided in 2 types:
Latching commands (J10): 8 ports for high impedance inputs ( max +/- 25 mA). Connect to external devices with
third-party protection/power circuits. Referenced to VBAT.
Latching Out (J9): 8 ports. This outputs includes drivers for the latching device. No external drivers are needed.
Referenced to VBAT.

3.8 Solid State Relays

The board features four configurable 60V 2.5A solid state relays with galvanic isolation available in J11. Typical
applications include HVAC, sprinkler control etc.
