UCLC/BNC 

 The UCLC-BNC is equipped with a BNC terminal for input from the "SA" model Li-Cor sensors. The BNC connecter has the advantage of more easily attached and detatched than the screw down terminals provided in the stock UCLC. The disadvantages of the BNC connecter are that it is not waterproof, and that it is more expensive. If your project will require the UCLC to be exposed to water and yet you have a "SA" model Li-Cor sensor, there are two possible options to persue. One option is to cut the BNC connecter off of the end of the Li-Cor sensor cable, strip back the ends of the wires, and then tin them with solder. This procedure will allow use of the stock model, waterproof UCLC enclosure. Click here to download detailed instruction on how to remove the BNC connector from your LICOR light sensor (PDF). Another option would be to seal the BNC connector with silicone rubber tape.

At right is a picture illustrating the interior of the UCLC-BNC. The blue jumpers allow for the current-loop amplifier to be set to different imputs and outputs, just as in the stock UCLC. The UCLC-BNC shown is set for input from a LI-190SA (left jumper) and an output of 4-20 mA (right jumper).
