Description:

  

The Pololu basic 2-channel relay carrier modules allow simple, independent control of two single-pole, double-throw (SPDT) switches from low-voltage, low-current control signals.

 

The Pololu basic relay carrier modules make it easy to control a single-pole, double-throw (SPDT) switch from low-voltage, low-current control signals.  The modules are available with 5 V power relays—Omron G5LE-14-DC5 —and is pre-soldered.

 

The carrier board routes the three relay control pins to 0.1″-spaced pins compatible with standard solderless breadboads and female servo cable connectors.  This board has a 0.1″ straight male header soldered to these pins.  The relay switch pins are routed to a set of large pads intended for use with a 3-pin 5mm-pitch terminal block and a set of smaller pads with a 0.2″ pitch, making them compatible with 0.1″ perfboards.  This board has a terminal block soldered to these pins.  The carrier board has four mounting holes that work with #2 or M2 screws.

  

The switch portion of the relays is accessible on one side of the board while the control pins are routed to the other.  The relay coils are powered by supplying 5 V across the VDD and GND pins, and they are activated by digital high control signals on their respective EN pin.  The control signals are fed directly to the BSS138 N-channel MOSFETs, which in turn actuate the relay coils when the signal voltage exceeds approximately 2.5 V. 

 

The relay switch terminals COM (common), NO (normally open), and NC (normally closed) are routed on the PCB with a minimum clearance of 60 mils (1.5 mm) from other copper. The copper traces are designed to be at least 45 mil (1.1 mm) from the board edges, though manufacturing variations in the board edges can make those distances slightly lower.

 

In most applications, the current and voltage ratings for the module will match the ratings of the relay used.  Maximum current, maximum voltage, and life expectancy are interdependent; we therefore recommend careful examination of your relay’s datasheet.

 

  

Warning: This product is not designed to or certified for any particular high-voltage safety standard.  Working with voltages above 30 V can be extremely dangerous and should only be attempted by qualified individuals with appropriate equipment and protective gear.
