I have a 8 Relay Board. It is a legacy product from 2010 and never has been used. I want to use it but I can´t find any information as to how to get it to work. I don´t see any model number but only: R8XPL Rev A. It has 8 Omron Relays and a Ethernet Module (Digi). I could send a picture, but to what email? Can you redirect me to a instalation or user manual of this device.
