##Main features

* 2 digital input channels for push buttons, switches, relays or positive voltage line
	* Max input voltage: 48 Volt
	* Input LC Pi filter to reduce high frequency noise
	* Status led on board for any channel:
		* Led ON: Open or input voltage > 1.8 volt 
		* Led OFF: Open or input voltage < 1.8 volt 
* 2 normally open, 1 way relay contact channels
	* Max voltage: 250VAC or 220VDC 
	* Max switching power: 60 Watt
	* Max current: 2A
	* Status led on board for any channels:
		* Led RLx ON: Contact closed
		* Led RLx OFF: Contact open

The daisy connectors where to plug this board are:

| Board  | Daisy Connector | Note  |
|--------|-----------------|-------|
| FOXG20 | D2              | Up to 2 boards |
| FOXG20 | D5              | Up to 2 boards |
| TERRA  | D11             | Up to 2 boards |
| TERRA  | D12             | Up to 2 boards |

A [Daisy-1](/DAISY-1) adapter is required on the FOX Board G20 .
