The ETH484 provides four volt free contact relay outputs with a current rating of up to 16 Amp each, 8 digital I/O and 4 analogue inputs. The relays are SPCO (Single Pole Change Over) types. The normally open, normally closed and common pins are all available on the screw terminals.
The module is powered from a regulated or unregulated 12Vdc supply. The DC input jack is 2.1mm with positive core polarity, DC supplies are required to supply at least 500mA at 12vdc.
A new feature has been added that allows the digital inputs to remotely control relays or digital outputs. Control outputs over the network or Internet.
