The Latching Solenoid Driver, LSD01, allows you to remotely control latching irrigation valves using QTech
The LSD01 operates the popular 12 Volt 4 Ohm DC single coil latching solenoid irrigation valves. This gives you the option to interface to the Baccara and Burmad type valves widely used in irrigation systems.
The LSD01 is designed to interface directly with the QTech WP2P, Multi-point Controller, SMS Controller,
SMS Lite and DATRAN RTU products.
A 12V DC (+/- 10%) power supply is required, at an operating current of 2 to 12mA.
The 12V DC supply is applied to the +12V and GND terminals of the LSD01.
• The solenoid valve is controlled by the RLY terminals on the LSD01, which operate as a trigger.
When the RLY terminals are closed the solenoid valve will turn ON. When the RLY terminals are opened
the solenoid valve will turn OFF.
• The solenoid valve coil wires are connected to the LSD01 terminals labelled BLK and GRN.
Note – If the solenoid valve operates in reverse, simply swap the BLK and GRN wires on the LSD01.
