The im2RL has two 5V, 1A relays with relay-driving circuitry. The relays can be controlled by 3.3V or 5V logic, making this module suitable for Modtronix boards, Arduino, AVR, Microchip PIC or nearly any other project that requires two relays.
This module makes the three relay outputs (Common, Normally Open, Normally Closed) available via a 6-pin, 3.5mm Pluggable Screw Terminal Block connector. The center pin of each relay's three is Common; left (viewing connector from above, facing up) is Normally Closed; and the right is Normally Open. They are also marked on the PCB with symbols.

iMod Pin Configuration This is an iMod module with 0.7" pin column width, meaning it uses a standard pinout and configuration that allows it to be connected easily to any host board that has an iMod port. This includes the Modtronix SBC83I, SBC66UAL, and the various PT66E Prototyping Add-ons for other boards in the SBC66 series.
The pin pitch is 0.1" so you can use the module also on any typical prototyping board or breadboard.
Below is some example code for the Netcruzer (SBC66/SBC66+PT66) boards that shows how to turn Relay A on and off, assuming this module is mounted in iMod port 1. For Relay B, you would use Pin 5.
imod1_ConfDirPin2(OUTPUT_PIN); //Configure pin 2 of iMod 1 as an output
imod1_WritePin2(1); //Set pin 2 of iMod 1 - Turn relay on
imod1_WritePin2(0); //Clear pin 2 of iMod 1 - Turn relay off

Pin Header Options Use the Headers option at the bottom of this page to select what type of pin headers you want included with the module and whether you want them included loose or pre-soldered. The default option is for common rectangular pins included loose (the photo above shows them soldered). All pin header types use 3mm long pins. As you can see in the photo above, two of the unused pins in the middle of one column are not installed.
Below the header option selector, you will see checkboxes for adding additional header strips (e.g. in case you want to populate all six pin pads per side), as well as socket strips that will mate with the Round Swiss pin header type. If you want to install the socket strips on your prototype so that you can plug in this module with Round Swiss pins, make sure to change and Update the quantity of sockets to 2 during checkout.
