The 4-20 mA Board for Waspmote has 4 input channels which allow the user to convert signals that come from 3

party sensors

or devices with this industrial standard. The 4-20 mA Board works with type 2, 3 and 4 current transmitters. Each channel can

be configured for working with these types of connections. If the jumper is moved away, the receptor (the 4-20 Board) will be

configured as float (type 4 connection).
