simonsez Posted December 29, 2017 Posted December 29, 2017 Hi, Wondering if someone can help me set up my Ezio 2x4? Specifically I am trying to figure out how to set it up to accomplish two functions. The first is to read a dry contact sensor (magnetic door sensor) in order to control a light. The second is to operate a fan based on the relay output of my UPS. However I am not sure how everything should be connected to the Ezio 2x4 terminals and if I need additional parts like resistors. Thanks in advance for any help. Simon
Brian H Posted December 30, 2017 Posted December 30, 2017 (edited) The relay output on the UPS. Is it also a dry contact? The users Quick Guide has this in it also. The module has two Opto-Isolated inputs. I1 and I2. You can connect the I1+ and I2+ to the +5 volt terminal of the module. Then the magnetic switch between I1- or I2- terminals and the ground terminal. Then the UPS relay output between the other I1- or I2- terminal and ground. If not too clear. Please ask for more data. Can't help with programming. It also has two Digital Inputs I3 and I4. If you have to have more dry contact inputs. The Guide show you how to use pull up resistors.

Hi Brian, The UPS outpout is indeed a dry contact. Thanks to your tips I got my EZIO up and running so it can respond to my UPS temperature events, and also for a magnetic switch to turn a light on and off when a door is opened and closed. Thank you very much for the help! Simon
